technical field

The utility model relates to a drum washing machine.

Background technique

There are two kinds of washing machines currently on the market, one is to rely on the rotation of the pulsator at the bottom of the washing tub to clean clothes; the other is to clean clothes by the rotation of the drum. No matter which type of washing machine, there is a spray device. During the washing and rinsing cycle, the spray device can spray the clothes inside the drum to promote the uniform dissolution of detergent, increase the washing effect of the washing machine, quickly eliminate the foam in the washing process, and improve the rinsing efficiency. There are many kinds of spraying devices of existing drum washing machines, such as Chinese patent: "A spraying device for drum washing machines (CN99220855.6)", which sets a circulating water pipeline between the bottom of the washing tub and the observation window glass pad. , Install the nozzle on the top of the observation window glass pad through the circulating water pump and pipe fittings. The nozzle is designed in the shape of a snake head, and its flat opening snake mouth nozzle sprays obliquely into the cavity of the washing inner cylinder, so as to increase the beating effect of washing and improve the washing degree of clothes. However, since the existing spray device is installed on the top of the rubber pad of the observation window, the space where the nozzle is located is relatively narrow, and the nozzle is in a single form, and the range of washing water sprayed into the drum is only at the outlet of the drum. , can not cover more drum inner space, so that the spray effect can not reach the best. In addition in the pulsator washing machine, such patent is arranged: " washing machine (CN99247037.4) ", it is fixed with a spray ring below the washing machine outer cylinder cover, is provided with an inlet and a plurality of spray forest mouths on the spray ring. The spray ring is fixed on the bucket of the washing machine through a bracket. When the washing machine is washing and dehydrating, the support strength of the spray ring is relatively high, and the structure is relatively complicated, the stability is not very good, and it is inconvenient to assemble, disassemble and maintain.
