Bubble generator and washing machine having the same
A washing machine having a bubble generator includes a bubble spray part provided at an upper side of a tub and configured to discharge bubbles from a top to a bottom inside the tub, a wash liquid jet nozzle provided inside the bubble spray part and configured to jet wash liquid; a blowing fan provided in the bubble spray part and configured to blow air in a direction in which the wash liquid jet nozzle jets the wash liquid; and a porous plate member provided at a front end of the bubble spray part and including a plurality of holes, wherein when the wash liquid jetted from the wash liquid jet nozzle collides with the porous plate member, bubbles are generated.
1. A washing machine comprising:
a tub; and
a bubble generator comprising:
a bubble spray duct provided at an upper side of the tub and configured to discharge bubbles from a top to a bottom inside the tub;
a wash liquid jet nozzle provided inside the bubble spray duct and configured to jet wash liquid;
a blowing fan provided on the bubble spray duct upstream from the wash liquid jet nozzle and configured to blow air in a direction in which the wash liquid jet nozzle jets the wash liquid in a manner that the air is blown around the wash liquid jet nozzle; and
a porous plate member provided at a front end of the bubble spray duct and including a plurality of holes,
wherein when the wash liquid jetted from the wash liquid jet nozzle collides with the porous plate member, bubbles are generated.
2. The washing machine of claim 1 , further comprising:
a wash liquid disperser provided in front of the wash liquid jet nozzle in a manner to disperse the wash liquid jetted from the wash liquid jet nozzle.
3. The washing machine of claim 2 , wherein a surface of the wash liquid disperser facing the wash liquid jet nozzle is formed in a spherical shape.
4. The washing machine of claim 2 , wherein the wash liquid disperser comprises a porous plate.
5. The washing machine of claim 1 , wherein the porous plate member comprises a perforated mesh or screen mesh.
6. The washing machine of claim 5 , wherein the porous plate member is formed in a convex shape protruding in a direction in which the wash liquid jet nozzle jets the wash liquid.
7. The washing machine of claim 1 , wherein:
the bubble spray duct includes a rectangular cross-section, and
the wash liquid jet nozzle is disposed at a center of the rectangular cross-section.
8. The washing machine of claim 1 , wherein:
the wash liquid jet nozzle is connected to a water supply pipe connected to an external water supply source, and
the water supply pipe is provided with a detergent suction part configured to suck detergent.
9. The washing machine of claim 8 , wherein the detergent suction part comprises a venturi pipe.
10. The washing machine of claim 1 , wherein:
the wash liquid jet nozzle is connected to a circulation pipe connected to a circulation pump and configured to circulate water received in the tub, and
the circulation pipe is provided with a detergent suction part configured to suck detergent.
11. The washing machine of claim 10 , wherein the detergent suction part comprises a venturi pipe.
12. The washing machine of claim 1 , wherein the wash liquid jet nozzle is connected to a circulation pipe connected to a circulation pump and configured to circulate water received in the tub.
13. The washing machine of claim 1 , wherein a dry duct provided with a heater is disposed between the bubble spray duct and the blowing fan.
