Abstract

The low frequency vibration washing machine includes a water basin(1), a disc(2) to induce a resonance in the multi-phase medium composed of water, detergent and air layers contained in the water basin(1), and a driving means(3) for the disc(2). The disc(2) is conical shape and has many protrusions(4) in shape of involute curve on the surface. These protrusions makes a flow of water by the vibrations of the disc(2) to turn the laundry. It prevents a jam of the laundry.

The present invention relates to a low frequency vibration washing apparatus, and more particularly, to a disk (low frequency oscillating diaphragm) which is installed in a water tank and serves to generate vibration while being moved by a driving means.

The low frequency vibration washing machine generates resonance at a specific frequency depending on the shape of the container, the shape of the disk and the composition ratio of the polyphase medium in the polyphase medium, which is a complex of water, detergent, and air in the tank. A washing machine that performs washing by combining mechanical energy caused by cavitation of micro air bubbles in a multiphase medium or chemical action by detergent and chemical energy caused by nonlinear vibration, and enables efficient washing by inputting minimum energy necessary for resonance. .

The basic configuration of the low-frequency vibration washing apparatus as described above is that the vessel containing the polyphase medium, such as the first diagram, is installed in the water tank 1 and the water tank to cause resonance in the polyphase medium, and to drive the disk. Comprising the drive means (3) is formed between the disk and the bottom surface of the tank is a suitable gap so that the disk can vibrate up and down.

Accordingly, when the disk 2 is moved up, down, left, and right by the driving means 3, water flow is formed in the polyphase medium contained in the water tank 1 by the vibration, and the laundry moves along the water flow.

However, the disk installed in the low frequency vibration washing machine as described above was in the form of a simple disk, and a lot of power was required to resonate the water.

The reason for this is that when the disk rises, as shown in Fig. 1, a water column is formed in the center portion of the tank and cavitation occurs at the edge portion of the disk, so that the disk has a large resistance.

In addition, when the disk is continuously moving up and down linearly, the laundry hits the disk and damages the attachments (buttons, etc.). The disk does not move even when the disk moves linearly. There is a problem that the washing efficiency is lower than the circulation.

An object of the present invention is to provide a vibrating washing apparatus capable of driving the disk with a smaller power, minimizing damage to the laundry, and efficient washing while circulating the laundry.

According to the above object of the present invention, the disk applied to the apparatus of the present invention has a conical shape, and an involute curved protrusion is formed on the surface thereof. Damage is prevented and power consumption is reduced.

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

2 is a plan view and a front view showing an embodiment of the disk to be applied to the present invention, the disk (2) is formed to be inclined so that the upper and lower portions protrude toward the center from the outer diameter surface as a whole in a circular shape of the disk, A plurality of involute curved projections 4 are formed on the upper and lower surface portions.

Therefore, when the disk 2 vibrates by the driving means, water flows in the hole portion between the involute type 4 formed in the disk 2 as in the third diagram, and the disk rotates by the hydraulic force. The water flow is formed by the flow of water as described above, and the laundry moves along the water flow.

In addition, the involute projection 4 has a shape that becomes wider and thicker gradually from the center of the disk toward the outside, which smoothly flows and swirls the water flowing into the grooves between the protrusions. This is to cause strong water flow.

4 is a front view of a disc according to another embodiment of the present invention. FIG. 4 is an example in which only the upper portion of the disc 2 protrudes into a conical shape to form the protrusion 4, and FIG. 4 is a disc ( It is an example in which the projection 4 is formed by protruding only the lower part of 2) into a conical shape.

In the above embodiment, the disk is rotated by the purified water flow when the disk vibrates, and the laundry moves along the water stream.

In addition, the involute curve direction of the projection 4 formed in the disk can be in any direction such as clockwise or counterclockwise.

As described above, the present invention forms a disk in a conical shape and forms an involute-shaped protrusion on the surface thereof, thereby preventing the phenomenon of water column rising in the washing machine during washing, and at the same time reducing the cavitation phenomenon. The disk can be driven evenly.

In addition, since the disk rotates while the disk moves up and down, the impact force when the laundry contacts the disk is greatly reduced than when the disk does not rotate, thereby preventing damage to the laundry. Since the laundry flows due to the circulating water flow, the laundry can be prevented from being caught between the disk and the bottom of the tank, and the washing efficiency can be improved.
