2 is a cross-sectional view showing a state in which the diaphragm of the air bubble generator according to the present invention is moved upward, and FIG. 3 is a cross-sectional view showing a state in which the diaphragm of the air bubble generator according to the present invention is moved downward. 2 and 3, a first body 30 having a predetermined accommodation space is provided therein, and an upper end side of the first body 30 is connected to communicate with the inside of the first body 30. The tube 32 protrudes upward. A male screw 34 is formed on the outer circumferential surface of the connecting pipe 32. A motor 38 having a rotating shaft 36 is provided, which is mounted in the receiving space of the first body 30 such that the rotating shaft 36 is located at the lower end of the portion where the connecting pipe 32 protrudes. do. Cam 40 is provided to be eccentrically fixed to the free end of the rotation shaft 36 of the motor 38. A rubber plate 42 is disposed between the motor 38 and the first body 30 to absorb and reduce vibration generated when the motor 38 is driven. The connecting body 44 having the same inner diameter as the outer diameter of the cam 40 is provided, and the connecting piece 46 protrudes outward on one side of the outer circumferential surface of the connecting body 44.

A diaphragm 48 having an outer diameter equal to the inner diameter of the connecting pipe 32 protruding from the upper end side of the first body 30 is provided, and the connecting piece 46 is fixed to the lower end of the diaphragm 48. . A second body 54 having a small diameter portion 50 and a large diameter portion 52 is provided on the inner side, and the inner circumferential surface of the large diameter portion 52 of the second body 54 is formed on the outer circumferential surface of the connecting pipe 32. A female screw 56 is formed to engage the male screw 34. On one side of the small diameter portion 50 of the second body 54 is formed a receiving space 60 in communication with the small diameter portion 50 by a connecting passage 58. On one side of the upper end of the second body 54, an air outlet 64 for discharging the introduced air into the washing tub of the washing machine is protruded outward. The air outlet 64 communicates with the receiving space 60 formed inside the second body 54. One side of the air inlet 62 and the connecting passage 58 is provided with a first opening and closing plate 66 and a second opening and closing plate 68 for selectively opening and closing the air inlet 62 and the connecting passage 58. .

The operation state and effect according to the air bubble generator configured as described above will be described.

When the motor 38 mounted in the accommodation space of the first body 30 is converted to the "on" state, the cam 40 rotates to be eccentric to the rotation shaft 36 and the rotation shaft 36 of the motor 38. . When the cam 40 fixedly rotated to the rotation shaft 36 and the rotation shaft 936 by the driving of the motor 38 is rotated, the connecting body 440 in close contact with the outer circumferential surface of the cam 40 moves in the vertical direction. That is, when the motor 38 is driven because the cam 40 fixedly eccentrically fixed to the rotation shaft 36 of the motor 38 is in close contact with the inside of the connecting body 44, the connecting body 44 is eccentric. When the connecting body 44 moves in the vertical direction, the diaphragm 48 moves in the vertical direction according to the movement of the connecting body 44. That is, the connecting body 44 is moved in the vertical direction. When the cam 40 is eccentrically rotated by the driving of the motor 38 because the connecting piece 46 is fixed to the lower end of the diaphragm 48, the diaphragm 48 is moved in the vertical direction. When moved in the vertical direction, outside air flows into the second body 54 through the air inlet 62 and at the same time through the air outlet 64. When the diaphragm 48 is moved downward, the outside air flows in through the air inlet 62 formed at one upper end of the second body 54. At this time, one side of the first opening and closing plate 66 provided on the inner upper end of the second body 54 to selectively open and close the air inlet 62 has a state away from the air inlet 62. When the diaphragm 48 is moved upward, one side of the first opening / closing plate 66 provided at the inner upper end of the second body 54 is in close contact with the air inlet 62 and at the same time flows through the air inlet 62. The compressed air is discharged to the washing tub of the washing machine through the air outlet 64. In this case, the connection passage 58 is selectively provided to the receiving space 60 of the second body 52 to selectively open and close the connection passage 58. One side of the second opening and closing plate 68 has a state of being dropped in the connecting passage 58. In the vertical movement of the diaphragm 48 Accordingly, as the outside air is sucked and supplied to the washing tank of the washing machine in a compressed state, air bubbles are generated in the washing tank.

According to the driving of the motor 38, the outside air is discharged to the washing tank of the washing machine in the compressed state to easily generate air bubbles, and the air is supplied to the washing tank in the compressed state to improve the washing force as compared to the existing. It can be. In addition, since the rubber plate 42 is interposed between the motor 38 and the first body 30, vibration and noise are not generated when the motor 38 is driven.

As described above, the air bubble generator of the washing machine according to the present invention is configured to be discharged to the washing tank of the washing machine in a compressed state according to the driving of the motor, thereby improving washing power as well as reliability of the product. It will have the effect to increase.
