Description

一种洗衣机的喷淋***及洗衣机Spraying system and washing machine of washing machine 技术领域Technical field
本发明属于洗衣机技术领域，具体的涉及一种洗衣机的喷淋***及洗衣机。The invention belongs to the technical field of washing machines, and in particular relates to a sprinkling system of a washing machine and a washing machine.
背景技术Background technique
原来的滚筒洗衣机在洗完衣服后，往往在窗垫和玻璃上存在少量的泡沫，用户在取衣服时，会将这些泡沫带到洗好的衣服上，泡沫多时甚至需要再次漂洗。随着用户的要求不断提高，大多数高端洗衣机采用了双喷淋设计，在程序即将运行结束时，将窗垫和玻璃上的泡沫给冲洗干净，但是现有结构设计一般是通过一根很长的软管，将喷淋头和进水阀相连接，直接喷淋。结构中间不存在任何加压和分压设计，当水压过小时，两个喷淋嘴会出现喷淋水量不足或者喷淋不均匀等现象。而喷淋结束后，由于洗衣机桶内压力大于外界压力，喷淋管中的部分水不能完全喷出，又会导致用户在开门的瞬间，喷淋管中的水滴出机器外。The original drum washing machine often has a small amount of foam on the window mat and the glass after washing the clothes, and the user will bring the foam to the washed clothes when taking the clothes, and even need to rinse again when the foam is long. As the user's requirements continue to increase, most high-end washing machines use a dual-spray design to flush the foam on the window mat and glass at the end of the program, but the existing structural design is generally a long one. The hose connects the sprinkler to the inlet valve and sprays directly. There is no pressure and partial pressure design in the middle of the structure. When the water pressure is too small, the two spray nozzles may have insufficient spray water or uneven spray. After the spraying is finished, because the pressure in the barrel of the washing machine is greater than the external pressure, part of the water in the spray pipe cannot be completely ejected, which may cause the user to drop water out of the machine at the moment of opening the door.
