Description

Drum type washing machine provided with external blade on the outer periphery of washing drum

The present invention relates to a drum washing machine, and more particularly, a plurality of outer wings are attached to the outer wall of the washing tank in the longitudinal direction, and the washing liquid is pumped up with the outer blades according to the rotation of the washing tank in the washing operation, and the washing machine is re-introduced from the upper side of the washing tank. The present invention relates to a drum washing machine provided with an outer wing of a washing tub for improving washing power by dropping washing liquid.

In general, a washing machine includes a pulsator type using water flow by rotation of a pulsator and a drum type using impact force due to vertical fall of laundry by rotation of a drum.

Among them, the drum washing machine is generally coaxially arranged with the reservoir 103, the reservoir 105 mounted inside the cabinet 103, and the reservoir 105, as shown in FIG. Cabinet 103 with a minimum shaking state of the washing tank 107 for washing the laundry put into the interior, the drive motor 113 and the reservoir 105 for rotationally driving the washing tank 107 by the belt 109 and the pulley 111. It is composed of a suspension device consisting of a spring 115 and a damper 117 to support), and other devices for drainage and water supply and various connection devices are additionally attached.

The front side of the washing tank 107 is provided with a door 121 which is connected in a watertight state by the door bellows 131 for access to the laundry, and the drum slide 123 is integrally attached to the rear of the washing tank 107. The rotary shaft 125 of the washing tub 107 protrudes and is rotatably supported by the bearing 127 on the bearing housing 129 on the central portion of the drum slide 123.

A plurality of locking jaws 119 are attached to the inner circumferential surface of the washing tank 107 to lift the laundry upwards as the washing tank 107 rotates forward and backward, and a drain hose 133 on one side of the bottom surface of the storage tank 105. ) Is connected to the drainage pump 135 operates to drain the washing solution is finished.

In general, the conventional drum type washing machine 101 having the configuration as mentioned above is to wash the laundry through the following process.

First, when the laundry is put into the washing tank 107 and the washing machine 101 is operated, after the water is supplied into the washing tank 107 through the water supply valve and a predetermined quantity is supplied, the washing liquid is heated by the heater 112 while the motor is heated. 113 is driven, and the rotational force of the motor 113 generated through the motor pulley 137, the drive belt 109, the belt pulley 111, the rotating shaft 125 and the drum slide 123 through the washing tank ( 107). When the washing tank 107 rotates by the rotational driving force transmitted in this way, the laundry in the washing tank 107 is lifted upward by the lift 119 protruding from the inner circumferential surface of the washing tank 107 and then falls downward again. The impact on the washing liquid, and the impact force generated at this time, the contaminants on the laundry come off the laundry, washing is performed by repeating this drop motion several times.

The washing tank 107 repeats the forward and reverse rotation at a low speed, that is, about 50 to 55 rpm while the washing operation is performed, and when dewatering, the washing tank 107 rotates at a high speed, that is, at a speed of 800 to 1000 rpm. After exiting the reservoir 105 through a number of fine holes (not shown) formed in the circumferential wall of the washing tank 107 is drained out through the drain hose 133 by the pumping force of the drain pump 135.

At this time, as shown in Figure 2 during the washing in the washing tank 107 and the reservoir 105, the water surface 110 stays at the 1/3 point at the bottom, so the laundry is caught up by the catching jaw 119, the water surface from the top ( Impact force generated while falling to 110) or only the flow of the washing water flowing from the bottom of the washing tank 107 to the left and right can be used as the washing force. Although the impact generated helps a little in washing, the amount of water to be pumped up was not very helpful in improving washing power.

In order to overcome the limitation of the washing power increase by such washing water, a plurality of brushes 205 on the inner circumferential surface of the washing tank 203, such as the drum washing machine 201 disclosed in the Korean Utility Model Registration Application No. 89-20240 shown in FIG. Drum washing machine with a has been proposed.

Like the drum washing machine 201, the drum washing machine 201 receives washing liquid flowing through the water supply pipe 209 into the water tank 207 and washes and rinses by the rotational movement of the washing tank 203 rotating forward and backward in the water tank 207. After the dehydration, the water is discharged through the drain pipe 211 to finish a series of washing operations. In particular, in addition to the dropping of the laundry during the washing process, the washing force was improved by the frictional force of the brush 205. At the time of washing, since the rotation speed of the washing tank 203 is not large, the friction force is not largely generated between the laundry and the brush 205.

Therefore, the present invention is devised to solve the disadvantages of the conventional drum washing machine as mentioned above, by attaching a plurality of outer wings in the longitudinal direction to the outer wall of the washing tank in accordance with the rotation of the washing tank during the administration of the outer wing The purpose of the present invention is to improve the washing power by adding washing power according to the washing liquid drop to the washing power of a general drum washing machine by dropping the washing liquid again from the upper side of the washing tank to the inside of the washing tank.

In order to achieve this object, the present invention is provided with a laundry tank into which the laundry is put in a horizontal arrangement in the storage tank, a plurality of laundry stopper is formed in the longitudinal direction on the inner circumferential surface of the washing tank, a plurality of laundry liquid through the washing tank A drum washing machine having a circulation hole, the drum washing machine having a washing tank outer blade attached to the outer circumferential surface of the washing tank is attached in a state in which the plurality of outer wings are maintained at a constant interval in the washing tank circumferential direction and extended in the washing tank length direction.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

4 and 5, the drum washing machine 1 according to the present invention has an exterior cabinet 3, a laundry tank 7 into which laundry is put, and a storage tank 5 in which laundry liquid is filled, as in a conventional drum washing machine. And a suspension motor 17 which attaches and supports the driving motor 13 and the water storage tank 5 to the cabinet 3 to generate the rotational driving force of the washing tank 7.

The front side of the washing tank 7 is provided with the door 21 for injecting laundry, and this door 21 is connected with the cabinet 3 in the state which keeps watertightness by the door bellows 31. As shown in FIG. The rotating shaft 25 protruding from the rear side of the washing tank 7 is supported by the water storage tank 5 so as to be rotatable by a bearing mounted on the bearing housing, and is wound around the belt pulley 11 attached to the end of the rotating shaft 25. Receiving the rotational force of the drive motor 13 by the (12) rotates the washing tank 7 in the forward and reverse directions.

In addition, a plurality of washing liquid distribution holes 10 are formed in the washing tank 7 and attached to the inner circumferential surface of the washing tank 7 at regular intervals in a state in which a plurality of locking jaws 9 extend in the washing tank 7 lengthwise direction. The drainage hose 33 is connected to the bottom surface of the water storage tank 5, and a drainage pump 35 for extracting the washing liquid is provided in the middle of the drainage hose 33.

In addition, a plurality of outer wings 8 are attached to the outer circumferential surface of the washing tub 7 as shown in FIGS. 4 to 6, where the outer wings 8 are the washing tub 7 like the locking jaw 9. It is arrange | positioned so that a fixed space | interval may be maintained in the circumferential direction of the washing tank 7 in the state extended in the longitudinal direction.

In addition, each of the outer wings 8 is in the form of a single foil, in the case shown in Figures 4 and 6, the space portion opened in the same direction as any one of the rotation direction (A) of the washing tank 7 capable of forward and reverse rotation Although not shown, 16 may be arranged and attached so that the open positions of the space portions 16, which are adjacent to the outer blades 8, are formed in a circumferential shape.

In addition, since the outer blade 8 is made of an elastic material such as rubber and protrudes outward in the radial direction of the washing tub 7, the rotation speed of the washing tub 7 is remarkably high when dehydration occurs, and abnormal vibration is generated or in the case of severe washing tub 7 Even if the gas is removed, the washing tank 7 and the water storage tank 5 can be prevented from directly contacting the collision.

According to the drum washing machine 1 of the present invention configured as described above, the laundry is first introduced into the washing tank 7, and then the washing liquid is supplied from the water supply pipe 31 to the water storage tank 5 via the detergent container 37. When the water level of the supplied washing liquid 2 reaches an appropriate value, washing is started while the washing tank 7 starts to rotate. At this time, the laundry in the washing tank (7) is pulled up in the rotational forward and reverse direction by the locking jaw (9) and is washed while repeating the process of falling from the upper end of the washing tank (7), at the same time the washing liquid is also by the locking jaw (9) Slightly scooped up and dropped, washing laundry at the bottom.

In particular, as the washing tank 7 rotates, it is held in the bottom of the water storage tank 5 by the outer blades 8 and is enclosed in the outer wing 8 space 16 to be pumped up to the upper side of the washing tank 7. The liquid is poured in the direction of the arrow B of FIG. 4 through the washing liquid flow hole 10 to further increase the washing power by impacting the laundry moving left and right at the bottom of the washing tank 7.

At this time, when the space 16 opening positions of all the outer blades 8 are directed to the same side as shown in Fig. 4, the washing liquid is only applied when the washing tub 7 rotates in either direction. When the outer blades 8 are arranged to face each other in opposite directions, the washing liquid may always be pumped regardless of which direction the washing tub 7 rotates.

Thus, after washing is completed, the drain hose 33 connected to the bottom surface of the reservoir 5 is opened, and the drain pump 35 is operated to extract the washing liquid through the drain hose 33.

Then, when the rinsing is finished, a predetermined dehydration stroke proceeds. When dehydration, excessive vibration occurs in the washing tub 7 so that the washing tub 7 moves largely back, forth, left and right, and the outer blade 8 is elastic such as rubber. Since it is made of material and protrudes on the outer circumferential surface of the washing tank 7, the washing tank 7 is prevented from directly colliding with the inner circumferential surface of the water storage tank 9, and the self-aligning function of restraining the washing tank 7 vibration toward the center axis line You can expect.

As described above, according to the drum washing machine of the present invention, a washing liquid accumulated between the water storage tank and the washing tank during washing by a plurality of outer wings attached to the washing tank outer circumferential surface to be maintained at a predetermined interval in the circumferential direction is extended. The washing tank is pumped up in the forward and reverse direction to be poured into the washing tank from the upper position of the washing tank.

Therefore, since the potential energy of the washing liquid is kinetic energy is applied to the laundry located below the washing tank by an increased impact compared to the conventional drum washing machine, it is possible to improve the washing power.

In addition, since the outer wing is made of an elastic material, the washing tank has a certain elasticity in the radial direction, so that even if the washing tank vibrates excessively during the dehydration process or severely malfunctions, the water tank and the washing tank are directly contacted with each other. This prevents the life of the drum washing machine. Although the present invention has been shown and described with respect to particular embodiments, it is well known in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the accompanying Utility Model Claims. Anyone who owns it can easily find out.
