Description

Technical Field

The present invention belongs to the field of laundry processing devices, and in particular relates to a supporting component and a laundry processing device provided with the supporting component.

Background Art

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.

Detailed Description of the Embodiments

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

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.
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.
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.
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.
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.
The second supporting pieces 102 support the object in a contacting manner, thereby playing a role of positioning support, and being more easily stable.
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.
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.
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.
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.
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.
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.
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

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.
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.
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.
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.
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.
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.
Wherein the distance between the peripheral wall of the supporting roller and the side wall of the drum component is 0.5-5mm,
More preferably, the distance between the peripheral wall of the supporting roller and the side wall of the drum component is 1mm.
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.
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.
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.
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.
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.
Further, the supporting component is arranged below the drum component 100.
More preferably, the supporting component is arranged below the front of the drum component 100.
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.
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.
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.
The laundry processing device includes a dual-drum washing machine, a drum washing machine or a dryer.

Embodiment 3

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.
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.
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.
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.
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.
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.
The distance L between the peripheral wall of the supporting roller and the side wall of the drum component is 1mm.
A front supporting plate 107 is arranged inside the box, and the first mounting bracket 103 is mounted on the front supporting plate 107.
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

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
More preferably, all the first supporting pieces 101 are arranged on the same radial section of the drum component 100.
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.
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.
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

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 the drum component 100 in a contacting manner, and the first supporting piece 101 being separated from the drum component 100. At least one first supporting piece 101 is arranged above the drum component.
