Description

A kind of rotary drum washing machine
Technical field
The utility model relates to household appliance technical field, especially relates to a kind of pulsator washing machine.
Background technology
Washing machine can be divided into stirring-type, drum-type and impeller-type three types usually.
The inner core central authorities of agitator type washing machine are provided with a stirring rod and several agitators, stirring rod and agitator can according to different clothing quality, degree of fouling, washings quality etc. or rotate back and forth soon or slowly within the scope of 360 °, and clothing is pulled rub back and forth in bosom, realize removing spot.Agitator type washing machine has outstanding clean ability, but in washing process, sound is comparatively large, can produce excessive rocking, and wear of clothes is also more serious.
Tumbling-box washing machine has the cylinder that the horizontal or tilting inner surface of level is provided with the rolling rib of multiple projection usually.During washing, water, washing agent and clothing are loaded in cylinder, and cylinder slowly runs under the drive of motor.Clothing is constantly promoted and is thrown in cylinder, then promotes and throw, does repeating motion.Just in this repeating motion process, clothing under the acting in conjunction of washing powder and water by washes clean.Tumbling-box washing machine have not damaging laundry, water loss few, washed the advantages such as rear clothing can not be wound.But on the other hand, tumbling-box washing machine has the noise be harmful to health, and consumes power is many, and be that fully clean its required time of clothing is relatively long.
Pulsator washing machine utilizes the frictional force produced between the current of motion and clothing to carry out washing clothes, and wherein, the motion of water is generally rotate generation by a discoidal impeller with positive and negative direction.Pulsator washing machine has outstanding clean ability, and required wash time is shorter.In addition, pulsator washing machine also have noise low, shake the advantages such as little, price is more cheap.
Fig. 1 shows a kind of partial sectional view of existing pulsator washing machine.See Fig. 1, be provided with one and in this urceolus, be provided with an inner core 2 rotationally for holding the cylindrical outer barrel (not shown) of water in casing 1, the sidewall of inner core 2 is provided with multiple hole 2a that water can be made to flow between inside and outside cylinder.An impeller 3 is arranged on the inside bottom of inner core 2, and this impeller 3 is connected with a driving shaft (not shown), and this driving shaft is driven by a motor (not shown).The upper surface of impeller 3 is provided with the washing rib 3a of multiple upwards projection radially from center.During work, the forward and reverse rotation of impeller, washings form the current of rotation under washing rib 3a stirs, and rub, thus reach the object of washing clothes between this current and clothing.The top of casing 1 is also provided with a top cover 4 and a case 5, and case 5 is used to open or close the opening that can be seen washing machine internal.In addition, the sidewall of inner core 2 is also provided with usually the filter screen 6 for filtering the flock formed in laundry processes.
Because pulsator washing machine relies on current to wash, therefore, current are most important to clean ability, and current stir generation by the impeller rotated, and limit by impeller shape and rotation mode thereof.
