Various detergent dissolving apparatuses may be used, but in the present embodiment, it is shown that the ultrasonic generator 300 is used as shown in FIG. 4.

Ultrasound is a wave generated by the vibration of air or an object, and when an object vibrates, the surrounding air vibrates together, which vibrates the ear's eardrum and makes it soundable. Sound waves are waves propagating from an elastic body, and the material points forming the elastic body are compressed and then propagated. In gas, liquid, solid, etc., members are elastic with each other, so sound waves may exist in principle. In this case, the ultrasonic wave means a sound wave that is high in frequency and cannot be heard by an ear, that is, a sound wave that exceeds an audible frequency range (16 Hz to 20 KHz).

When an object is put in water and ultrasonic waves are generated in the water, when the ultrasonic waves propagate into the water, micro bubble groups are generated and extinguished by the large pressure change of the ultrasonic waves. This pressure and high temperature occur for short periods of time from hundredths to thousands of seconds. This powerful force decomposes the solid detergent.

As shown in FIG. 4, the ultrasonic generator 300 according to an embodiment of the present invention includes a vibrator 310 for generating ultrasonic waves by converting electrical energy into mechanical vibration energy, and the vibrator 310. Coupled to the booster 320 and the booster 320 to enlarge the amplitude of the ultrasonic wave generated in the vibration unit 310, the ultrasonic wave enlarged in the booster 320 to the water in the powder detergent storage unit 221a It includes a transmitting horn (330).

FIG. 5 is a cross-sectional view illustrating that the ultrasonic wave generator 300 is installed in the detergent supply device 142 in FIG. 3, and the operation of the detergent supply device 142 will be described with reference to FIG. 5.

When the user injects the powder detergent and the liquid detergent into the detergent container 220 and then pushes the detergent container 220 into the housing 200, the ultrasonic generator 300 installed in the housing 200 passes through the hole 223. It is inserted into the powder detergent storage unit 221a through.

Then, when the user operates the washing machine by turning on the power switch (on), the water supply valve 141 is opened and water is supplied to the detergent container 220. When a predetermined amount of water is supplied to the detergent container 220, the water supply valve 141 is closed, and a predetermined amount of water is stored in the detergent container 220.

The ultrasonic generator 300 operates after a predetermined amount of water is stored in the detergent container 220.

Referring to the operation of the ultrasonic generator 300 as follows.

When an electrical signal is applied to the vibrator 310, the piezoelectric ceramics (not shown) embedded in the vibrator 310 vibrate repeatedly by contracting and expanding.

At this time, since the vibration of the piezoelectric ceramics (not shown) is not large, the vibration of the piezoelectric ceramics (not shown) is received from the booster 320 coupled to the vibration unit 310 to enlarge the amplitude even more. Let's do it.

The enlarged vibration is transmitted to the water in the powder detergent storage unit 221a by the horn 330.

When vibration is transmitted to the water inside the powder detergent storage unit 221a, cavitation bubbles are generated in the water. The cavitation bubbles are formed at a high temperature and high pressure, which is generated when the bubbles are broken. Due to the high temperature and high pressure shock wave, the solid detergent in the water is decomposed.

And this pressure and high temperature occur for short periods of time from hundredths to thousands of seconds. This powerful force allows the solid detergent to dissolve well in water without clumping.

As described above, when the ultrasonic generator 300 is operated for a predetermined time and the detergent is dissolved in water, the driving means 207 is operated to rotate the opening and closing wall 222 installed at the rear side of the powder detergent storage unit 221a. . When the opening and closing wall 222 rotates to open the rear side of the powder detergent storage unit 221a, the powder detergent dissolved in water is supplied into the tub 120 through the drain hole 207 and the water supply bellows 143.

As described above, the washing machine according to the present invention can dissolve the powder detergent of the detergent supply device 142 in water by using the ultrasonic generator 300, thereby improving washing efficiency.

In addition, even if a small amount of detergent is used to improve the washing efficiency it is possible to reduce the amount of detergent used.
