[0002] A drum-type clothes dryer is provided with a drum for
accommodating clothes. Since clothes need to be delivered into the
drum, the drum is designed to be open at one end (or two ends). To
ensure that the clothes to be dried can be dried uniformly and
rapidly, the drum rotates by a motor via belt driving. When the
drum rotates, the open end cannot be connected with housing
arranged outside the drum through the shaft structure at the shaft
center of the drum. Therefore, a drum which can rotate freely is
required to effectively support the open end of the drum.
[0003] In the field of existing drum clothes dryers, the
manufacturing and assembling manners of the drum supporting wheels
can be divided into two types: the first type is that a rolling
bearing (standard parts) and a drum hub as a whole are subject to
insert molding, and the hub component after insert molding is then
subject to the second insert molding with an outer tyre (semihard
material); the second type is that the rolling bearing (standard
parts) is firstly subject to preassembly with two hub parts of
metal plate material (two hub parts of metal plate material clamp
the roller therebetween), riveted or spot-welded for fixation
through TOX, and then the well-assembled hub component of a metal
plate material and the outer tyre (semihard material) are subject
to insert molding.
[0004] At present, each positioning roller of the supporting

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0039] In order to understand more clearly the object, technical
solutions and advantages of the embodiments in the present
invention, a clear and complete description is given below on
technical solutions in the embodiments in combination with
accompanying drawings in the embodiments of the present invention.
The following embodiments are used for describing the present
invention, rather than for limiting the scope of the present
invention.
Embodiment 1
[0040] As shown in FIG. 1 to FIG. 3, a supporting component is
provided. The supporting component is configured to support an
object. The supporting component includes a first mounting bracket
103 and a first supporting piece 101 and second supporting pieces
102 arranged on the first mounting bracket 103. The second
supporting pieces 102 support the object in a contacting manner,
and the first supporting piece 101 and the object are arranged at
intervals.
[0041] The first supporting piece 101 and the second supporting
pieces 102 are all arranged on the first mounting bracket 103,
wherein the second supporting pieces 102 support the object in a
contacting manner for supporting the object on the supporting
component. When an object moves towards the supporting component
under a great force, in addition to support of the second
supporting pieces on the object, at this time, the first supporting
piece 101 is in contact with the object, to realize compensation
support to the object, and enable the support for the object by the
supporting component more stable.
[0042] Further, the first supporting piece 101 and/or the second
supporting pieces 102 are rolling pieces arranged on the first
mounting bracket 103 in a rotatable manner. The second supporting
pieces 102 are tangent to the same circumference, and the first
supporting piece 101 is arranged on an outer side of the
circumference.
[0043] The second supporting pieces 102 are rolling pieces, such
that the contact support between the object and the second
supporting piece 102 is in rolling contact. The friction force is
smaller, and the stability is favorable. The contact support
between the first supporting piece 101 and the object is the same
as the above principle.
[0044] The second supporting pieces 102 are tangent with the same
circumference, and the first supporting piece 101 is arranged at
the outer side of the circumference. An inner layer of support and
an outer layer of support are formed on the supporting piece, such
that when the object vibrates or jumps violently, in addition to
the second supporting pieces, the first supporting piece is in
contact with the object, to provide a compensation supporting force
to the object, and enable the object to be more easily
balanced.
[0045] The second supporting pieces 102 support the object in a
contacting manner, thereby playing a role of positioning support,
and being more easily stable.
[0046] Solution 1,the first supporting piece 101 and the second
supporting pieces 102 are both rollers. The outer side walls of the
second supporting pieces 102 are tangent with the same
circumference, and the first supporting piece 101 is arranged at
the outer side of the circumference. Specifically, the roller is
connected with the first mounting bracket 103 through a bolt, and
the circular side wall of the roller is in contact with and
supports the object.
[0047] Solution 2,the first supporting piece 101 and the second
supporting pieces 102 are both balls. The peripheral walls of the
second supporting pieces 102 are tangent with the same
circumference, and the first supporting piece 101 is arranged at
the outer side of the circumference. Specifically, the first
mounting bracket 103 is provided with a groove, the balls are
arranged in the groove, the upper end of the balls protrudes out of
the notch of the groove, and the object is supported by the
peripheral wall of the ball in a contacting manner.
[0048] Further, the second supporting pieces 102 are arranged at
two sides of the first supporting piece 101. The second supporting
pieces 102 at two sides support the object in a contacting manner,
to form supporting points at two sides of the first supporting
piece 101, such that the positioning of the object is more
accurate, and the object is more easily balanced, and the support
of the supporting piece on the object is more stable. The first
supporting piece 101 is arranged between the second supporting
pieces 102, and the compensation support of the first supporting
piece 101 on the object is distributed on the second supporting
pieces at two sides in a more balanced manner, such that the object
is more easily balanced.
[0049] Solution 1,the second supporting pieces 102 are provided,
one first supporting piece 101 is provided, and the second
supporting pieces 102 are arranged at two sides of the first
supporting piece 101.
[0050] Solution 2,multiple first supporting pieces 101 and second
supporting pieces 102 are provided, and at least one supporting
piece 101 is arranged between any two adjacent second supporting
pieces 102.
[0051] In a further solution, the second supporting pieces 102 are
symmetrical about the first supporting piece 101, so the structure
enables the object to be more stable on the supporting
component.
[0052] For example, one first supporting piece 101 is provided, two
second supporting pieces 102 are provided, and the two second
supporting pieces 102 are symmetrical about the connecting line
between the first supporting piece 101 and the center of the
circumference. That is, the first supporting piece 101 and the two
second supporting pieces 102 are arranged to be of an isosceles
triangle on the supporting bracket, and the distance from the first
supporting piece 101 to the left second supporting piece 102 is
equal to the distance from the first supporting piece 101 to the
right second supporting piece 102, such that the compensation
supporting force generated by the first supporting piece 101 is
distributed uniformly on the second supporting pieces 102 at two
sides, and the object is more easily balanced.
Embodiment 2
[0053] As shown in FIG. 1 to FIG. 3, the present embodiment relates
to a laundry processing device provided with a supporting component
of embodiment 1. The laundry processing device includes a drum
component 100, the supporting component is configured to support
the drum component 100. The second supporting pieces 102 support
the drum component 100 in a contacting manner, and the first
supporting piece 101 is separated from the drum component 100 by a
certain distance. When the drum component 100 performs eccentric
movement, the first supporting piece 101 supports the drum
component 100 in a contacting manner.
[0054] When the drum component 100 rotates, the second supporting
pieces 102 support the drum component 100 in a contacting manner,
to support the drum component 100. However, if clothes inside the
drum component are not distributed uniformly, the drum component
100 easily performs eccentric movement during rotating, then the
drum component 100 may possibly jump and deviate from the original
movement trail. Through setting the first supporting piece 101
which supports the drum component 100 in a contacting manner when
the drum component 100 performs eccentric movement, compensation
support is provided to the drum component 100, such that the drum
component 100 returns to the original movement trail again, thereby
improving the stability of the supporting component on the drum
component 100, and reducing damage.
[0055] Further, the first supporting piece 101 is a supporting
roller 101, the second supporting pieces 102 are positioning
rollers 102. The positioning rollers 102 are in rolling contact
with the side wall of the drum component 100, the supporting roller
101 is separated from the side wall of the drum component 100 by a
certain distance, and the supporting roller 101 is in rolling
contact with the drum component 100 when the drum component 100
performs eccentric movement.
[0056] Specifically, two positioning rollers 102 are provided, one
supporting roller 101 is provided, and two positioning rollers 102
are arranged at two sides of the supporting roller 101. The
positioning rollers 102 are in rolling contact with the side wall
of the drum component 100, the supporting roller 101 is separated
from the side wall of the drum component 100 by a certain distance,
and the supporting roller 101 is in rolling contact with the drum
component 100 when the drum component 100 performs eccentric
movement.
[0057] The drum is in a rotating state during operation, and the
supporting component is provided with the supporting roller 101 and
the positioning rollers 102, so that when the positioning rollers
102 is in rolling contact with the drum component 100, the friction
resistance is reduced, the impedance of the positioning roller 102
on the rotating drum component 100 is reduced. At this time, the
supporting roller 101 is not in contact with the drum component
100. When the drum component 100 performs eccentric movement, the
supporting roller 101 is in rolling contact with the drum component
100, to provide compensation support to the drum component 100,
such that the drum component easily returns to be in contact with
the positioning roller 102, and the support is more stable.
[0058] Further, the distance between the first supporting piece 101
and the side wall of the drum component 100 is not greater than the
largest eccentric distance of the drum component 100. If the
distance between the first supporting piece 101 and the side wall
of the drum component 100 is too large, even if the drum component
100 is eccentric, the first supporting piece 101 still cannot
support the drum component 100. If the distance between the first
supporting piece 101 and the side wall of the drum component 100 is
too small, then compensation support can be performed on slight
eccentricity, and the service life will be influenced with frequent
compensations. Therefore, a better compensation supporting effect
can be achieved through controlling the distance between the first
supporting piece 101 and the side wall of the drum component
100.
[0059] Wherein the distance between the peripheral wall of the
supporting roller and the side wall of the drum component is 0.5-5
mm,
[0060] More preferably, the distance between the peripheral wall of
the supporting roller and the side wall of the drum component is 1
mm.
[0061] Further, the supporting roller 101 corresponds to the lowest
point of the drum component, and the positioning rollers 102 at two
sides of the supporting roller are symmetrical about a straight
line which passes through the center of the supporting roller 101
and the center of the drum component 100.
[0062] Specifically, two positioning rollers 102 are provided. The
two positioning rollers are respectively arranged at two sides of
the supporting roller, and are symmetrical about the straight line
which passes through the center of the supporting roller and the
center of the drum component, such that two positioning rollers 102
are arranged on the same vertical height.
[0063] Further, the first mounting bracket 103 is provided with an
arc notch 106, and the drum component 100 is arranged in the arc
notch 106 of the first mounting bracket 103. The supporting roller
101 and the positioning rollers 102 are both distributed along an
edge of the arc notch 106, the second supporting pieces 102 support
the outer wall of the drum component 100 in a contacting manner,
and the first supporting piece 101 is separated from the outer wall
of the drum component 100 by a certain distance.
[0064] An arc notch 106 is set for accommodating the drum component
100 and setting of the supporting roller 101 and the positioning
rollers 102. The supporting roller 101 and the positioning rollers
102 are distributed along the edge of the arc notch 106.
[0065] More preferably, the supporting roller 101 is arranged in
the middle of the arc notch 106, and the positioning rollers 102
are arranged at two ends of the arc notch 106.
[0066] Further, the supporting component is arranged below the drum
component 100.
[0067] More preferably, the supporting component is arranged below
the front of the drum component 100.
[0068] Since the rear part of the drum component 100 is connected
with an output shaft of the driving device to drive the drum
component 100 to rotate and the front end is suspended, the
supporting component is arranged below the front of the drum
component 100 for supporting more stably.
[0069] Further, the first mounting bracket 103 is provided with a
buffer supporting part which is configured to buffer the impact
force of the drum component 100 on the first supporting piece
101.
[0070] Preferably, the first mounting bracket 103 includes a body
and a triangular bracket. The triangular bracket and the body are
molded to form a buffer supporting part, and the first supporting
piece 101 is arranged at the vertex position of the triangular
bracket.
[0071] The laundry processing device includes a dual-drum washing
machine, a drum washing machine or a dryer.

[0072] As shown in FIG. 1 to FIG. 3, the present embodiment is a
specific solution of embodiment 2. A washing-drying machine
includes a box 105, and a drum component 100 and a supporting
component arranged in the box 105. The rear part of the drum
component 100 is connected with the driving device which drives the
drum component 100 to rotate, and the front part is suspended. A
supporting component is arranged below the drum component 100, such
that the drum component 100 is more stable in the rotating
process.
[0073] The supporting component is arranged below the front of the
drum component 100. When the drum component 100 is in eccentric
state, the eccentric distance at this position is the largest. When
the supporting component is set at this position, the drum
component 100 is more easily balanced.
[0074] The supporting component includes a first mounting bracket
103, two positioning rollers 102 and one supporting roller 101. The
positioning rollers 102 and the supporting roller 101 are arranged
on the first mounting bracket 103 in a rotatable manner. The
rotating shafts of the positioning roller 102, the supporting
roller 101 and the drum component 100 are in parallel with each
other, and the positioning roller 102, the supporting roller 101
and the drum component 100 are arranged in the same plane.
[0075] The upper part of the first mounting bracket 103 is provided
with an arc notch 106 with an upward opening. Two positioning
rollers 102 and one supporting roller 101 are distributed along an
arc edge of the arc notch 106, and two positioning rollers 102 and
one supporting roller 101 all protrude out of the edge of the arc
notch 106.
[0076] The supporting roller 101 is arranged in the middle of the
arc notch 106, and corresponds to the lowest point of the drum
component 100, and two positioning rollers 102 are arranged at two
ends of the arc notch 106. Two positioning rollers 102 are in
bilateral symmetry about a straight line which passes through the
center of the supporting roller 101 and the circle center of the
drum component 100. That is, two positioning rollers 102 are on one
circumference and are arranged on the same vertical height. Two
positioning rollers 102 are arranged on the same vertical height.
Two positioning rollers 102 are lower than the center of the drum
component 100.
[0077] The drum component 100 is arranged at the inner side of the
arc notch 106. When the drum component 100 is overlapped on the arc
notch 106 of the supporting component, the positioning rollers 102
support the outer wall of the drum component 100 in a contacting
manner, and the supporting roller 101 is separated from the drum
component 100 by a certain distance. When the drum component
performs eccentric movement, the supporting roller 101 is in
contact with the drum component 100 to support the drum component
100.
[0078] The distance L between the peripheral wall of the supporting
roller and the side wall of the drum component is 1 mm.
[0079] A front supporting plate 107 is arranged inside the box, and
the first mounting bracket 103 is mounted on the front supporting
plate 107.
[0080] In the configuration, the supporting roller is only arranged
below the drum component, so that when the drum component performs
eccentric movement, compensation support cannot be applied to the
upper part of the drum component. To solve the problem, at least
one supporting piece is arranged at the upper part of the drum
component.
Embodiment 4
[0081] In the structure in embodiment 1 to embodiment 3,the first
supporting piece 101 is only arranged below the drum component 100.
When the drum component 100 performs eccentric movement,
compensation support cannot be applied to the upper part of the
drum component 100. To solve this problem, at least one first
supporting piece 101 is arranged at the upper part of the drum
component 100.
[0082] As shown in FIG. 4 to FIG. 5, a supporting component is
provided. The supporting component is configured to support the
drum component 100 of the laundry processing device, and includes
first supporting pieces 101 and second supporting pieces 102. The
second supporting pieces 102 support the drum component 100 in a
contacting manner, and the first supporting pieces 101 and the drum
component 100 are arranged at intervals. At least one first
supporting piece 101 is arranged at the upper part of the drum
component 100.
[0083] The second supporting pieces 102 support the drum component
100 in a contacting manner, such that the drum component 100 is
supported on the supporting component. Under normal conditions, the
first supporting piece 101 is not in contact with the drum
component 100. When the drum component 100 performs eccentric
movement, the first supporting piece 101 is in contact with the
drum component 100, to support the drum component 100 and play an
effect of correcting the deviation. Through setting a first
supporting piece 101 above the drum component 100, when the drum
component 100 performs upward eccentric movement, the first
supporting piece 101 is in contact with the drum component 100, to
produce a downward force to correct the deviation.
[0084] In a further solution, at least one first supporting piece
101 is arranged at the lower part of the drum component 100, the
second supporting pieces 102 are arranged at two sides of the
connecting line between the lowest point of the drum component 100
and the center of the drum component 100, and the first supporting
piece 101 arranged below the drum component 100 is arranged between
multiple second supporting pieces 102.
[0085] The first supporting pieces 101 are simultaneously arranged
above and below the drum component 100. When the drum component 100
performs eccentric movement, normal operation is rapidly recovered,
to prolong the service life of the drum component 100 of the
laundry processing device and the bearing part connected with the
drum component 100.
[0086] In a further solution, a first supporting piece is arranged
below the drum component, and the first supporting piece
corresponds to the lowest point of the drum component. When the
first supporting piece 101 is arranged at the position, the drum
component 100 is more easily balanced.
[0087] In a further solution, the second supporting pieces 102 at
two sides of the first supporting piece 101 are symmetrical about
the connecting line between the first supporting piece 101 and the
circle center of the drum component 100. The second supporting
pieces 102 are set to be symmetrical at two sides of the first
supporting piece 101. When the drum component 100 is in eccentric
state, the drum component 100 is more easily balanced.
[0088] More preferably, a first supporting piece 101 is arranged
below the drum component 100, and each of the two sides of the
first supporting piece 101 is respectively provided with one second
supporting piece 102. The two second supporting pieces 102 are in
bilateral symmetry about the first supporting piece 101.
[0089] In a further solution, a certain included angle is formed
between the connecting line between the first supporting piece 101
above the drum component 100 and the circle center of the drum
component 100 and the connecting line between the highest point of
the drum component 100 and the circle center of the drum component
100. Generally, the mounting space at the highest point of the drum
component 100 is small, so when the first supporting piece 101
above the drum component 100 is set to be eccentric, mounting is
easier.
[0090] The distance between each first supporting piece 101 and the
peripheral wall of the drum component 100 can be equal, and each
supporting piece 101 supports the drum component 100 when the drum
component 100 produces the same eccentric distance. The distance
between each first supporting piece 101 and the peripheral wall of
the drum component 100 can be different, for example, at a certain
position. The influence on the shaft is larger when the drum
component 100 is eccentric at a position. The distance between the
first supporting piece 101 and the peripheral wall of the drum
component 100 is small at the position, otherwise, the distance set
is large.
[0091] Solution 1,each first supporting piece 101 is separated from
the peripheral wall of the drum component 100 by an equal distance.
The distance between the first supporting piece 101 above the drum
component 100 and the peripheral wall of the drum component 100 is
equal to the distance between the first supporting piece 101 below
the drum component 100 and the peripheral wall of the drum
component 100.
[0092] Solution 2,the distance between the first supporting piece
101 above the drum component 100 is different from the distance
between the first supporting piece 101 below the drum component 100
and the peripheral wall of the drum component 100.
[0093] More preferably, the distance between the first supporting
piece 101 below the drum component 100 and the peripheral wall of
the drum component 100 is larger than or equal to the distance
between the first supporting piece 101 above the drum component 100
and the peripheral wall of the drum component 100. Under the
influence of such factors as the weight of the drum component 100
and the weight of clothes inside the drum component 100, the upward
eccentric distance of the drum component 100 is small. Therefore,
the distance between the first supporting piece 101 above the drum
component 100 and the peripheral wall of the drum component 100 is
set to be small, and the effect of correcting the deviation is
better.
[0094] More preferably, the spaces between the first supporting
pieces 101 below the drum component 100 and the peripheral wall of
the drum component 100 are the same.
[0095] Further, at least part of the first supporting pieces 101
are arranged on the same radial section of the drum component 100.
In this way, the supporting force generated by the part of the
first supporting pieces 101 is on the same plane, and is more
easily balanced. The first supporting pieces 101 are divided into
two groups, and the two groups of supporting pieces 101 are
arranged respectively at the front and rear of the second
supporting piece 102.
[0096] More preferably, all the first supporting pieces 101 are
arranged on the same radial section of the drum component 100.
[0097] More preferably, all the first supporting pieces 101 and the
second supporting pieces 102 are respectively arranged on the same
radial section of the drum component 100.
[0098] Further, the first supporting pieces 101 and/or the second
supporting pieces 102 are rolling pieces, and the rolling pieces
are in rolling contact with the drum component 100.
[0099] Preferably, the rolling piece is a roller, a ball or a
bearing. Through the rolling contact between the rolling piece and
the drum component 100, the friction force is reduced, and the
service life is prolonged.
Embodiment 5
[0100] As shown in FIG. 4 to FIG. 5, a laundry processing device
provided with the supporting component of embodiment 4 includes a
drum component 100, the second supporting pieces 102 for supporting

supporting piece 101 being separated from the drum component 100.
At least one first supporting piece 101 is arranged above the drum
component. When the drum component 100 performs upward eccentric
movement, the first supporting piece 101 above the drum component

is arranged below the front part of the drum component 100. The
first supporting bracket 103 and the second supporting bracket 104
are both mounted with the front supporting plate 107 through
screws.
[0110] Two positioning rollers 102 and one supporting roller 101
are arranged along the edge of the arc notch 106. Two positioning

of the drum component 100 is also L.
[0112] The radius of the supporting roller 101 is equal to the
