Problems solved by technology

However, since the conventional washing machine generally has only one nozzle or two nozzles, the spraying direction of the fluid sprayed into the drum is limited, so there is a problem that the fluid cannot be uniformly sprayed onto the laundry contained in the drum.
However, since such a conventional washing machine generally has one nozzle or two nozzles, the direction of spraying through the nozzles is limited, and thus the clothes cannot be uniformly wetted.
[0012] In recent years, although a new technology of controlling the rotation of the drum to diversify the flow of laundry put in the drum has been developed, there is a limitation that a significant improvement in performance cannot be expected in the case of the conventional nozzle structure

no. 2 approach

[0806] Figure 63 is a view for explaining a control method of a washing machine according to another embodiment of the present invention.

[0807] refer to Figure 63 The controller may control the washing motor such that the laundry in the drum 32 rises by a first angle along the rotation direction of the drum 32 while being in contact with the side surface portion 321 of the drum 32 .

[0808] The first angle may be an angle less than 90 degrees. The controller may perform a rolling action to rotate the drum 32 in one direction so that the laundry on the side surface portion 321 of the drum 32 falls from a position corresponding to a position where the rotation angle of the drum 32 is less than about 90 degrees.

[0809] Alternatively, the first angle may be an angle between 90 degrees and 130 degrees. The controller may perform a tumbling action to rotate the drum 32 in one direction so that the laundry on the side surface portion 321 of the drum 32 falls from a positio...

[0853] Figure 64 is a view for explaining a control method of a washing machine according to another embodiment of the present invention.

[0854] According to the third embodiment, the nozzles may include a pair of middle nozzles 610b and 610e and a pair of lower nozzles 610c and 610d. The nozzles may include a pair of middle nozzles 610b and 610e, a pair of lower nozzles 610c and 610d, and an upper nozzle 610a.

[0855] The upper nozzle 610a may be a nozzle for supplying circulating water or a direct water nozzle for supplying water not mixed with detergent introduced through the water supply valve. Alternatively, the upper nozzle 610a may be a nozzle for supplying water mixed with the fabric softener while passing through the detergent container containing the fabric softener.

[0856] Hereinafter, nozzles will be described based on the case of an upper nozzle 610a, a pair of middle nozzles 610b and 610e, and a pair of lower nozzles 610c and 610d.

Abstract

The present invention relates to a washing machine comprising: a casing having a insertion hole for inserting laundry thereinto on the front surface thereof; a tub disposed in the casing and containing laundry water and having an inlet communicating with the insertion hole; a drum, rotatably disposed within the tub, for accommodating laundry; a pump for pumping water discharged from the tub; a gasket for making the insertion hole communicate with the inlet of the tub and having a plurality of nozzles for spraying water into the drum; and a nozzle water supply pipe, fixed to the gasket and having an inlet through which water pumped by the pump flows, for dividing and guiding water that has flowed through the inlet into a first sub flow and a second sub flow, the nozzle water supply pipe including a plurality of first nozzle water supply ports, formed on a first flow passage to which the first sub flow is guided, for supplying the first sub flow individually to any two or more nozzles among the plurality of nozzles, and a plurality of second nozzle water supply ports, formed on a second flow passage to which the second sub flow is guided, for supplying the second sub flow individually to other two or more nozzles among the plurality of nozzles.

Description

technical field [0001] The present invention relates to a washing machine having a nozzle for discharging water discharged from a tub and circulated along a circulation pipe into a drum. Background technique [0002] In general, washing machines separate dirt from clothes, bedding, etc. (hereinafter collectively referred to as "clothes") by using chemical decomposition of water and detergent and physical actions such as friction between water and clothes. installation. [0003] Such a washing machine includes a tub containing water and a drum rotatably installed in the tub to receive laundry. Recently, washing machines are configured to circulate water drained from a tub by using a circulation pump, and spray the circulated water into a drum through nozzles. However, since such a conventional washing machine generally includes a single nozzle or two nozzles, the spraying direction is restricted not only in the case of the single nozzle but also in the case of the two nozzl...
