Description

[FIELD OF THE INVENTION]



[0001] The present invention relates to a press-dewatering rubber tub for a continuous washing machine and, more specifically, to a press dewatering rubber tub for a continuous washing machine, in which a completely washed laundry is pressed to be dewatered in the continuous washing machine.

[BACKGROUND OF THE INVENTION]



[0002] As shown in FIG. 1, generally in a continuous washing machine configured by about 8-10 compartments, when laundries are continuously injected into the washing machine through one side of the machine by means of a loading conveyor (1), the laundries are washed in the process of sequentially moving to respective washing compartments (3), into which detergent has been injected, in a state of being sufficiently soaked with washing water in an immersion compartment (2), and when the laundries are completely washed, the laundries finally undergo a dewatering process in a dewatering part (6) after passing through a softening compartment (4) and a rinse compartment (5).

[0003] At this time, each of the compartments, in which immersion, washing, and rinsing are performed, has an inner structure where a rib is attached to the surface of an inner wall of a cylindrical tub thereof. Therefore, when the tub is rotated, the laundry held by the rib is moved to the upper side of the tub, so that the laundry is washed by a falling force caused while the laundry falls down from the upper side.

[0004] At this time, washing water is moved in the direction opposite to the moving direction of the laundry, thereby washing the laundry by using clean water gradually.

[0005] Meanwhile, FIG. 2 illustrates a schematic structure of a dewatering part (6). A dewatering rubber tub (6a) is pressed downward by a driving cylinder (6b) so as to press a laundry moved into a dewatering tank (6c), thereby dewatering the laundry.

[0006] However, the conventional dewatering rubber tub (6a) is filled with a predetermined amount of water (W) as an inner filler. Therefore, there is a problem that the weight of the dewatering rubber tub (6a) is increased due to the water, thereby increasing an amount of consumed power required for driving a cylinder.

[0007] In addition, when the dewatering rubber tub (6a) is blown out due to an increase in an internal pressure while being used, a high replacement cost is caused. Therefore, there is a problem of having a difficulty in maintenance of the continuous washing machine.

[0008] In order to solve this problem, utility model registration No. 20-0488262 (registration date: December 28, 2018) discloses "a press dewatering rubber tub for a continuous washing machine."

[0009] In a press dewatering rubber tub for a continuous washing machine according to utility model registration No. 20-0488262, the press dewatering rubber tub being mounted on a dewatering part, which is positioned on the rear end side of the continuous washing machine configured by a plurality of washing compartments, and being configured to be movable upward or downward by a driving cylinder so as to press a laundry in a dewatering tank, a plurality of high-elastic rubber balls as a filler for reinforcing durability have a hollow shaped therein and are stored in the dewatering rubber tub in a state that releasing of the rubber balls is prevented by an outflow prevention cover, an inner airtight force is increased while the inner airtight state of the dewatering rubber tub is formed by the outflow prevention cover, and an argon gas (g) is filled therein to prevent reduction of an elastic force of the rubber balls and prevent the rubber balls from being deformed or being oxidized.

[DETAILED DESCRIPTION FOR CARRYING OUT THE INVENTION]



[0019] Hereinafter, a press-dewatering rubber tub for a continuous washing machine according to a preferred embodiment of the present invention is described in detail with reference to the accompanying drawings.

<FIRST EMBODIMENT



[0020] A press-dewatering rubber tub for a continuous washing machine according to a first preferred embodiment of the present invention, the press-dewatering rubber tub (30) being mounted on a dewatering part, which is positioned on the rear end side of the continuous washing machine configured by a plurality of washing compartments, and being configured to be movable upward or downward by a driving cylinder (20) so as to press a laundry in a dewatering tank (10), a plurality of high-elastic honeycomb fillers (50) as a filler for reinforcing durability have a hollow shaped therein and are stored in the dewatering rubber tub (30) in a state that releasing of the honeycomb fillers (50) is prevented by an outflow prevention cover (32), an inner airtight force is increased while the inner airtight state of the dewatering rubber tub (30) is formed by the outflow prevention cover (32), and one of an argon gas, water, or air is filled therein to prevent reduction of an elastic force of the honeycomb fillers (50) and prevent the honeycomb fillers (50) from being deformed or oxidized.

[0021] FIG. 3 is a partially cut-away three-dimensional view showing a state where fillers are installed in a press-dewatering rubber tub for a continuous washing machine according to a first preferred embodiment of the present invention.

[0022] As shown in FIG. 3, a press-dewatering rubber tub (30) is mounted on a dewatering part, which is positioned on the rear end side of a continuous washing machine configured by a plurality of washing compartments, and is configured to be movable upward or downward by a driving cylinder (20) driven by hydraulic or pneumatic pressure, so as to press a laundry in a dewatering tank (10).

[0023] Particularly, in the present invention, a plurality of high-elastic honeycomb fillers (50) as a filler filled in the dewatering rubber tub (30) are stored therein in a state that releasing of the honeycomb fillers (50) is prevented by an outflow prevention cover (32).

[0024] At this time, the honeycomb fillers (50) used as a filler may be formed to have a hollow honeycomb-shape (hexagonal shape).

[0025] On the other hand, the honeycomb fillers (50) can be freely installed in the dewatering rubber tub (30) in the horizontal or vertical direction.

[0026] That is, as the honeycomb fillers (50) are vertically or horizontally installed in the dewatering rubber tub (30), the rigidity of the dewatering rubber tub (30) is sufficiently maintained when the driving cylinder (20) is operated to descend.

[0027] Meanwhile, the honeycomb fillers (50), which are horizontally installed, can be installed in such a manner as to be multiple-stacked to maintain a predetermined height thereof. Accordingly, the honeycomb fillers (50) are installed at a predetermined height, thereby saving an amount of water filled in the dewatering rubber tub (30).

[0028] The dewatering rubber tub (30) according to the first embodiment of the present invention has a lightweight structure so that a press-dewatering operation can be performed to a laundry while an ascent driving is further effectively performed.

[0029] That is, at this time, in a state where the laundry is input into the dewatering tank (10), dewatering is performed by pressuring the laundry as the dewatering rubber tub (30) is moved downward by an operation of the driving cylinder (20).

[0030] The dewatering rubber tub (30) of the present invention uses the honeycomb fillers (50) as an inner filler in a pressing process for dewatering, so that the weight of a structure can be reduced in comparison with a conventional technology using water as a filler.

[0031] Therefore, the weight of the dewatering rubber tub (30) can be reduced, thereby obtaining an effect of preventing the occurrence of a trouble due to a blowout of the rubber tub in a dewatering process as well as reducing an amount of consumed power required for driving a cylinder.

[0032] Moreover, water is not used as a filler so that a separation water supply device is unnecessary, thereby obtaining an advantage of improving a problem that a laundry is stuck due to a conventional water supply device.

<SECOND EMBODIMENT>

[0036] In the dewatering rubber tub (30), an inner airtight force is increased while the inner airtight state is formed by the outflow prevention cover (32), and one of an argon gas, water, or air is filled therein to prevent reduction of an elastic force of the square fillers (60) and prevent the square fillers (60) from being deformed or oxidized.

[0037] In the press-dewatering rubber tub for the continuous washing machine according to the second embodiment of the present invention, the square fillers (60) are installed in the dewatering rubber tub (30).

[0038] As shown in FIG. 4, the square fillers (60) can be installed in the dewatering rubber tub (30) in the horizontal direction as well as in the vertical direction.

[0039] Moreover, the square fillers (60) may be formed in various shapes such as a quadrate, oblong, rhombus, or oval shape.
