    • A washing machine and detergent delivery pump assembly thereof, the detergent delivery pump assembly comprising a pump (10), a plurality of pistons (20), a motor assembly (40), and a transmission mechanism (30, 50). The pump (10) is provided with a plurality of fixed-volume cavities (11) therein for receiving the detergent; each fixed-volume cavity (11) is provided with a liquid inlet valve (12) and a liquid outlet valve (13) thereon; the plurality of pistons (20) are disposed in each fixed-volume cavity (11) in one-to-one correspondence; each piston (20) comprises a piston head (21); the piston head (21) is controlled to reciprocate in the fixed-volume cavity (11) to suck in or push out a fixed-volume of detergent; the transmission mechanism (30, 50) is used to link the plurality of piston heads (21) with the motor assembly (40), and to control one of the piston heads (21) to move in the fixed-volume cavity (11) via the motor assembly (40). Therefore, the detergent dosing pump assembly of the present invention not only ensures the flexible and stable control of detergent delivery, but also enables the detergent delivery pump assembly to have a compact structure, thus effectively reducing manufacturing cost.
    • 一种洗衣机及其洗涤剂输送泵组件,洗涤剂输送泵组件包括泵(10),多个活塞(20),马达组件(40)和传动机构(30,50)。 泵(10)中设置有多个用于容纳洗涤剂的固定容积腔(11) 每个定容腔(11)上设有进液阀(12)和出液阀(13) 多个活塞20一一对应地设置在每个固定容积腔11中; 每个活塞(20)包括活塞头(21); 控制活塞头(21)在定量腔(11)内往复运动,吸入或排出固定体积的清洁剂; 传动机构30,50用于将多个活塞头21与马达组件40连接并控制其中一个活塞头21在固定容积腔11内移动, 经由马达组件(40)。 因此,本发明的洗涤剂计量泵组件不仅保证了洗涤剂输送的灵活和稳定的控制,而且使洗涤剂输送泵组件具有紧凑的结构,从而有效地降低了制造成本。
