[0022] A washing machine 100 according to embodiments of the present invention will be described
below with reference to Fig. 1 to Fig. 7.
[0023] The washing machine 100 according to embodiments of the present invention may include:
a cabinet 10, a cover 20 and a driving assembly 50. As shown in Fig. 3, the cabinet
10 has a worktable 13 which defines a port 11 for putting into and taking out of laundry.
Specifically, as shown in Fig. 1 to Fig. 3, the worktable 13 has a work surface 14,
and a button for controlling the washing machine 100 may be disposed at a periphery
of the work surface 14. The cover 20 is disposed on a top of the cabinet 10 and has
a cover frame 21 with a cover frame edge. The cover 20 is configured to be pivotable
about the cover frame edge for covering the port 11. The driving assembly 50 includes
a driving motor 30, and configured to drive the cover 20 to pivot about the cover
frame edge. That is, the driving assembly 50 may drive the cover 20 to rotate around
the cover frame edge to open or close the port 11. It should be understood that, by
providing the driving assembly 50, the washing machine 100 may realize a function
of the electric cover opening, so as to improve an automation degree of the washing
machine 100, and further improve experiences of users. Alternatively, the driving
motor 30 may be a reduction motor.
[0024] As shown in Fig. 1 and Fig. 2, the cover 20 can close the port 11. When the washing
machine 100 is working, the cover 20 closes the port 11 to ensure that the washing
machine works normally. Alternatively, when the washing machine 100 is not working,
the cover 20 closes the port 11 to prevent foreign objects from entering into the
interior of the washing machine 100 via the port 11, so as to protect the washing
machine 100 to at least some extent. As shown in Fig. 3, the cover 20 can open the
port 11, after clothes have been washed by the washing machine 100, the cover 20 may
open the port 11, so as to take out the clothes for drying.
[0025] As shown in Fig. 7, a receiving space for receiving the driving motor 30 is formed
in at least one corner of the worktable 13. It should be understood that, by disposing
the driving motor 30 at the corner ofthe worktable 13, the problem ofthe arrangement
ofthe driving motor 30 can be solved, and it is possible to further make the space
arrangement of the worktable 13 appropriate, and to reduce occupied space of the driving
motor 30 to facilitate the arrangement of other components (e.g., a detergent dispenser).
[0026] Specifically, the driving motor 30 has a motor portion 33 and a reducer portion 32,
the reducer portion 32 of the driving motor 30 has an upwardly-extending ear 31 adapted
to protrude from said work surface of the worktable 13, i.e. the ear 31 being extended
upwardly beyond the work surface 14 of the worktable 13. It should be understood that
the ear 31 is not disposed in or under the worktable 13, so that the space of the
worktable 13 occupied by the driving motor 30 may be effectively reduced, which may
further make the space arrangement of the worktable 13 appropriate to improve the
utilization rate of the space of the worktable 13.
[0027] Therefore, with the washing machine 100 according to embodiments of the present invention,
it is possible to realize a function of the electric cover opening and improve an
automation degree of the washing machine 100, and further improve experiences of users.
Moreover, by disposing the driving motor 30 at the corner of the worktable 13 and
extending the ear 31 upwardly beyond the work surface 14 of the worktable 13, the
problem of the arrangement of the driving motor 30 can be solved, and it is possible
to further make the space arrangement of the worktable 13 appropriate, and to reduce
occupied space of the driving motor 30 to facilitate the arrangement of other components
(e.g., a detergent dispenser).
[0028] Alternatively, the driving motor 30 defines a driving shaft hole (not shown), and
the driving shaft hole is formed in the ear 31. The driving motor 30 may be connected
to a component of the cover 20 at the driving shaft hole, so that the driving motor
30 may be configured to drive the cover 20 to pivot about the cover frame edge.
[0029] In some embodiments of the present invention, as shown in Fig. 6, the driving assembly
50 further includes an one-way bearing 40, the cover frame 21 has a bearing mounting
portion 22 at an end thereof, the one-way bearing 40 has a first end fixedly mounted
within the bearing mounting portion 22 of the cover 20 and a second end opposite to
the first end and connected to the driving motor 30, the driving motor 30 is configured
to drive the cover 20 via the one-way bearing 40 to pivot about the cover frame edge.
[0030] It should be understood that when the driving motor 30 is working, it may drive the
one-way bearing 40 to move. Because the one-way bearing 40 is fixed on the bearing
mounting portion 22, the cover 20 and the one-way bearing 40 move synchronously, that
is, the driving motor 30 may make the cover 20 open the port 11 by driving the one-way
bearing 40. As shown in Fig. 3 to Fig. 5, the bearing mounting portion 22 is disposed
at the cover frame 21 at the rear end of the cover 20, so as to rotate the cover 20
around the cover frame 21 as the pivotal axis. By providing the driving motor 30 and
the one-way bearing 40, the cover 20 is easy to rotate, which further simplifies the
structure ofthe washing machine 100. Alternatively, the driving motor 30 may be a
reduction motor. It should be understood that, the reduction motor may reduce the
output rotation rate to keep the opening rate of the cover 20 driven by the driving
motor 30 to be moderate.
[0031] Specifically, when the cover 20 needs to close the port 11, the driving motor 30
may drive the cover 20 to rotate around the cover frame 21 via the one-way bearing
40 to close the port 11.
[0032] In some embodiments, the cabinet 10 of the washing machine 100 may be provided with
a control button for opening or closing the cover 20. The control button is connected
with the driving motor 30, and the user only needs to press the control button to
realize the motion of opening or closing the cover 20, thus further improving an automation
degree of the washing machine 100 and experiences of users.
[0033] In addition, in the closing process of the washing machine 100, it is possible to
further complete the process of closing the cover 20 by pressing with manpower, and
the details are described as follows. Alternatively, as shown in Fig. 6, the one-way
bearing 40 includes an inner shaft portion 41 connected to the driving motor 30 and
an outer ring portion 42 fixedly mounted within the bearing mounting portion 22 of
the cover 20. When the driving motor 30 drives the one-way bearing 40 to open the
cover 20, the inner shaft portion 41 and the outer ring portion 42 move in the same
direction, so that the outer ring portion 42 may drive the cover 20 to rotate around
the cover frame 21, so as to enable the cover 20 to open the port 11. When the driving
motor 30 drives the one-way bearing 40 to close the cover 20, the driving motor 30
drives the inner shaft portion 41 to rotate, and the cover 20 associated with the
outer ring portion 42 moves downwardly under the effect of its own gravity to close
the port 11. The difference between the technical effect achieved using the one-way
bearing in the electric cover of the present invention and the technical effect achieved
without using the one-way bearing in the related art will be described in detail as
follows.
[0034] In the related art, when the cover is only driven by the driving motor without any
one-way bearing, if the driving motor is driven to rotate to a first direction, the
cover rotates to the first direction and the first direction is set to be a direction
of opening the cover; if the driving motor is driven to rotate to a second direction,
the cover rotates to the second direction and the second direction is set to be a
direction of closing the cover.
[0035] However, when the driving motor 30 according to embodiments of the present invention
drives the cover 20 via the one-way bearing 40, if the driving motor 30 is driven
to rotate to a first direction, the cover 20 rotates to the first direction and the
first direction is set to be a direction of opening the cover; if the driving motor
30 is driven to rotate to a second direction, the one-way bearing 40 and the inner
shaft portion 41 connected to the driving motor 30 rotate to the second direction,
the one-way bearing 40 and the outer ring portion 42 connected to the cover 20 will
not rotate if the cover 20 is not mounted. However, the cover 20 is mounted to the
outer ring portion 42, under the gravity of the cover 20, the outer ring portion 42
following the inner shaft portion 41 rotates to the second direction, so that the
cover 20 connected to the outer ring portion 42 falls down or becomes closed under
the gravity of the cover 20. If there is an obstacle such as human hand or foreign
object during the process of closing the cover 20, despite the inner shaft portion
41 of the one-way bearing 40 rotates under the drive of the driving motor 30, the
outer ring portion 42 may stop rotating because of the effect of the one-way bearing
40, and thus the cover 20 connected to the outer ring portion 42 may stop falling
or be stopped, which prevents the problem of clamping hand of the user by the cover
20, thus improving use safety of the washing machine 100. When the cover 20 is no
more obstructed by the hand and foreign object, it will continue to fall down under
the gravity effect to complete the motion of closing the cover. Therefore, the use
of the one-way bearing 40 on the driving motor 30 can prevent the problem of clamping
hands.
[0036] Obviously, during the process of closing the cover 20, if human hand presses further,
the cover 20 will be closed faster under pressure.
[0037] It should be understood that, the one-way bearing 40 and the driving motor 30 are
connected to be used, which is used for the electric cover of the washing machine
for the first time, and solves the problem of clamping hands by the electric cover.
[0038] Alternatively, because of an open end of the bearing mounting portion 22, the driving
motor 30 and the inner shaft portion 41 of the one-way bearing 40 are easily connected.
The one-way bearing 40 is entirely received in the bearing mounting portion 22 and
the inner shaft portion 41 of the one-way bearing 40 is extended out from an open
end of the bearing mounting portion 22. By receiving the entire one-way bearing 40
in the bearing mounting portion 22, it is possible to improve the reliability of mounting
the one-way bearing 40 on the cover 20. A part of the inner shaft portion 41 extending
out from the bearing mounting portion 22 may be connected to the driving motor 30.
[0039] Alternatively, as shown in Fig. 6, the outer ring portion 42 of the one-way bearing
40 may be provided with a positioning step 43 for locating a position with the bearing
mounting portion 22 and an elastic boss 44 for elastically pressing an inner wall
surface of the bearing mounting portion 22. By providing the positioning step 43 and
the elastic boss 44, the one-way bearing 40 may be detachably mounted on the bearing
mounting portion 22, so as to facilitate the mounting and dismounting of the one-way
bearing 40, and to maintain and replace the one-way bearing 40 in the later period.
Moreover, by providing the elastic boss 44, the mounting difficulty of mounting the
one-way bearing 40 onto the bearing mounting portion 22 may be reduced, and the mounting
stability of the one-way bearing 40 at the bearing mounting portion 22 may be improved.
Specifically, the positioning step 43 and the elastic boss 44 can be spaced apart
in an axial direction of the outer ring portion 42 (that is, a left-right direction
shown in Fig. 6), in which each bearing mounting portion 22 is provided with a groove
engaged with the positioning step 43 and another groove engaged with the elastic boss
44.
[0040] Alternatively, the driving motor 30 defines a driving shaft hole (not shown), and
at least a part of the inner shaft portion 41 is inserted into the driving shaft hole.
The driving motor 30 is provided with a ear 31 extended upwardly in a radial direction
of the driving motor 30, and the driving shaft hole is formed in the ear 31. That
is, the inner shaft portion 41 is extended into the ear 31 to cooperate with the driving
shaft hole, so that the driving motor 30 is connected to the inner shaft portion 41.
As shown in Fig. 4, the ear 31 can be abutted against an end surface of the end of
the bearing mounting portion 22. Specifically, the ear 31 can be abutted against an
end surface of an end of the bearing mounting portion 22 extending out from a part
of the inner shaft portion 41, and by attaching the ear 31 to the end surface of the
end of the bearing mounting portion 22, the driving motor 30 may cooperate with the
one-way bearing 40 steadily, and the structure may be compact, which may further save
space and improve the space utilization efficiency of the washing machine 100.
