Patent Description:
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.

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.

At present, each positioning roller of the supporting component is in rolling contact with the drum, to support the drum. However, when the drum performs eccentric movement, the supporting stability of the supporting component is poor. Therefore, it is a problem to be urgently solved to provide a supporting component which can rapidly recover stable support when the drum jumps.

In view of this, the present invention is hereby proposed.

<CIT> discloses a dryer with a rotatable drum supported by a three-roller support system arranged below the drum, wherein the three rollers of the support system are contacting the drum and are mounted to a rear bulkhead of the dryer.

The second supporting pieces <NUM> are tangent with the same circumference, and the first supporting piece <NUM> 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.

The second supporting pieces <NUM> support the object in a contacting manner, thereby playing a role of positioning support, and being more easily stable.

Solution <NUM>, the first supporting piece <NUM> and the second supporting pieces <NUM> are both rollers. The outer side walls of the second supporting pieces <NUM> are tangent with the same circumference, and the first supporting piece <NUM> is arranged at the outer side of the circumference. Specifically, the roller is connected with the first mounting bracket <NUM> through a bolt, and the circular side wall of the roller is in contact with and supports the object.

Further, the second supporting pieces <NUM> are arranged at two sides of the first supporting piece <NUM>. The second supporting pieces <NUM> at two sides support the object in a contacting manner, to form supporting points at two sides of the first supporting piece <NUM>, 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 <NUM> is arranged between the second supporting pieces <NUM>, and the compensation support of the first supporting piece <NUM> 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.

Solution <NUM>, multiple first supporting pieces <NUM> and second supporting pieces <NUM> are provided, and at least one supporting piece <NUM> is arranged between any two adjacent second supporting pieces <NUM>.

In a further solution, the second supporting pieces <NUM> are symmetrical about the first supporting piece <NUM>, so the structure enables the object to be more stable on the supporting component.

For example, one first supporting piece <NUM> is provided, two second supporting pieces <NUM> are provided, and the two second supporting pieces <NUM> are symmetrical about the connecting line between the first supporting piece <NUM> and the center of the circumference. That is, the first supporting piece <NUM> and the two second supporting pieces <NUM> are arranged to be of an isosceles triangle on the supporting bracket, and the distance from the first supporting piece <NUM> to the left second supporting piece <NUM> is equal to the distance from the first supporting piece <NUM> to the right second supporting piece <NUM>, such that the compensation supporting force generated by the first supporting piece <NUM> is distributed uniformly on the second supporting pieces <NUM> at two sides, and the object is more easily balanced.

As shown in <FIG>, the present embodiment relates to a laundry processing device provided with a supporting component of embodiment <NUM>. The laundry processing device includes a drum component <NUM>, the supporting component is configured to support the drum component <NUM>. The second supporting pieces <NUM> support the drum component <NUM> in a contacting manner, and the first supporting piece <NUM> is separated from the drum component <NUM> by a certain distance. When the drum component <NUM> performs eccentric movement, the first supporting piece <NUM> supports the drum component <NUM> in a contacting manner.

When the drum component <NUM> rotates, the second supporting pieces <NUM> support the drum component <NUM> in a contacting manner, to support the drum component <NUM>. However, if clothes inside the drum component are not distributed uniformly, the drum component <NUM> easily performs eccentric movement during rotating, then the drum component <NUM> may possibly jump and deviate from the original movement trail. Through setting the first supporting piece <NUM> which supports the drum component <NUM> in a contacting manner when the drum component <NUM> performs eccentric movement, compensation support is provided to the drum component <NUM>, such that the drum component <NUM> returns to the original movement trail again, thereby improving the stability of the supporting component on the drum component <NUM>, and reducing damage.

At this time, the supporting roller <NUM> is not in contact with the drum component <NUM>. When the drum component <NUM> performs eccentric movement, the supporting roller <NUM> is in rolling contact with the drum component <NUM>, to provide compensation support to the drum component <NUM>, such that the drum component easily returns to be in contact with the positioning roller <NUM>, and the support is more stable.

Further, the distance between the first supporting piece <NUM> and the side wall of the drum component <NUM> is not greater than the largest eccentric distance of the drum component <NUM>. If the distance between the first supporting piece <NUM> and the side wall of the drum component <NUM> is too large, even if the drum component <NUM> is eccentric, the first supporting piece <NUM> still cannot support the drum component <NUM>. If the distance between the first supporting piece <NUM> and the side wall of the drum component <NUM> is too small, then compensation support can be performed on slight eccentricity, and the service life will be influenced with frequent compensations.
