Abstract

The present invention relates to a washing machine, and more particularly, to a washing machine having a two-stage structure using ultrasonic waves to maximize a cleaning effect. The two-stage structure performs washing while a cradle holding a rack accommodating laundry moves up and down to the bottom and top of a washing tub, and enables simultaneous washing by additionally holding the rack accommodating laundry on the top when washing at the bottom of the washing tub.

Description

A washing machine having a two-stage structure using ultrasonic waves {ULTRASONIC WASHING MACHINE}

The present invention relates to a washing machine capable of washing various items, and more particularly, a holder for holding a rack accommodating washing water slides up and down to the bottom and upper part of the washing tub to perform washing and at the bottom of the washing tub. During ultrasonic cleaning, the upper part mounts a rack for additionally accommodating the washing material to maximize the washing effect by constructing a two-stage structure that enables washing with strong water pressure at the same time, as well as washing the washing material in three steps. It relates to a washer having a two-stage structure using ultrasonic waves, which can wash laundry more quickly and cleanly.

In general, a washing machine is a kitchen appliance that automatically washes, dries, and sterilizes dishes using water, electricity, and detergent.

The first washing machine, developed by Joel Houghton in 1850, was nothing more than a simple wooden machine that was manually turned on a wheel and sprayed with water. After that, Josephine Cochrane made a hand-operated washing machine, and after it was unveiled at the 1893 World's Fair, it became a big concern. to be.

In addition, the continuously improved washing machine has developed into a fully automated device with heated drying, preventing water spots, and reducing noise and water use.

The washing machine sets the tableware inside the housing, replenishes detergent and rinse, and presses the washing button, performs a series of soak washing, main washing, multiple rinse washing, etc., and then proceeds with the drying process and drying process. When finished, the power is automatically cut off.

On the other hand, in the case of a commercial washing machine, a housing having a large-capacity structure capable of handling a large amount of dishes, a washing room having a slide-type vertical lifting link on one side of the housing, a pump located inside the housing as a lower part of the washing room, and a washing machine It has a control circuit for controlling the operation program, a washing water tank, a rinsing water tank, a hot/cold water supply device, a detergent supply device, and a water spray device.

In such a conventional commercial washing machine, the water spraying device is typically of a pipe shape coupled to supply water to perform washing spray from upper and lower rotary plates provided with rinsing spray nozzles, and the vertical upper or lower portions of these upper and lower rotary plates. It has cleaning spray nozzles.

In addition, a rack or washing plate, such as a basket on which dishes are mounted, is placed on a cradle fixed to the inner surface of the washing chamber, and thus is disposed between the rotating plates.

Thereafter, each of the rinsing spray nozzles and the washing spray nozzles rotate together with the rotating plate during operation of the washing machine to spray hot or cold water.

The jetted water applies water pressure to the inner and outer surfaces of dishes mounted on the washing plate by a predetermined pressure and an inclination angle of the nozzle or an inclination angle according to rotation, thereby washing and rinsing the dirt and scale of the dishes.

However, in the case of a conventional commercial washing machine, since the water stream from the rinsing spray nozzle and the washing spray nozzle rotates with a change corresponding to the rotation of the rotating plate, by applying pressure to only a portion of the surface of the dishes placed in a fixed position in a certain pattern,

It is creating a so-called 'blind spot' where the pressure of water does not act.

Dirt and grime in these blind spots, as well as most of them will be cleaned thoroughly by operating the washer for a long time, using a lot of detergent, or increasing the temperature of the hot water, or waiting for the water to come into contact with the dirt on the surface of the tableware and soak it. Due to this, the consumption of water, detergent, and electricity, which are used as main resources for the operation of the washing machine, is further increased.

Such a conventional washing machine has a problem in that the operating efficiency and performance are relatively lowered, and the maintenance cost is higher than the manufacturing cost, and there is a problem in that the national environment and resources are wasted.

Hereinafter, the working relationship of the present invention will be described.

First, by raising the cover housing (C) of the present invention to the upper side, in a state in which the upper side of the main housing (H) is opened, the rack containing the washing water is mounted on the cradle 40 upper surface, and then the cover housing (C) is lowered to the main body Block the upper side of the housing (H).

After the washing material is seated on the holder 40 as described above, the washing material is primarily washed. This is to drive the lifting means 30 to transport the holder 40 to the lower side to transport the washing water to the inside of the washing tank 70 . After submerging, the ultrasonic cleaning of the washing material is performed through the ultrasonic generator 700 provided at the lower side of the washing tank 70 .

As described above, when the primary cleaning operation is completed, the holder 40 is raised and then the cleaning operation is performed secondary, which is the cleaning injection nozzle of the main injection unit 20 located on the inner upper part of the main housing (H) (H). 231) and at the same time spraying the washing water through the fixed spray nozzle 601 of the fixed spray unit 60 formed on the outside of the holder 40, the washing water contained in the holder 40 is secondary will be washed with

When the secondary washing operation is completed as described above, the washing operation is completed through the operation of rinsing the washing water, which is the rinsing injection nozzle 221 of the main injection unit 20 located on the inner upper part of the body housing (H). At the same time, the rinsing water is sprayed through the sub-injection nozzle 522 of the sub-injection unit 50 formed on the lower side of the cradle 40 to perform a rinsing operation of the washing water, resulting in rinsing the washing water. Of course, the rinsing water is selectively used among hot water and cold water as needed.

As described above, in the present invention, the washing operation is firstly performed by ultrasonic waves, the second washing operation is performed by washing water, and the first and second washing operations are completed as described above to completely remove foreign substances from the washing material. Thirdly, the rinsing operation with the rinsing water is performed, and due to this process, the washing of the washing material is performed faster and cleaner.

On the other hand, as described above, a separate auxiliary holder 41 is installed at a position before the holder 40 descends while the ultrasonic cleaning operation is in progress in the washing tank 70 for washing water for the first washing, and then the auxiliary holder (41) After mounting the rack containing the washing material on the upper surface, a separate washing operation can be performed,

Therefore, as described above, the washing material mounted on the holder 40 is ultrasonically cleaned in the washing tank 70 and at the same time, the washing product mounted on the auxiliary holder 41 is separately washed at the same time, resulting in a two-stage structure. By maximizing the effect, the time can be shortened and the washing material can be washed more cleanly.

As described above, although the present invention has been described with reference to the limited embodiments and drawings, the present invention is not limited to the above embodiments, and from the above description by those of ordinary skill in the art to which the present invention pertains. Of course, various modifications and variations may be possible.
