Document Type and Number:
WIPO Patent Application WO/2018/049857
Kind Code:
A1
Abstract:
Disclosed is a washing machine with a device for preventing dirt accumulation between an inner drum and an outer drum. The washing machine comprises a dirt accumulation prevention device comprising an electromagnetic water valve (6), water spray nozzles (5) and a control circuit. The dirt accumulation prevention device can spray tap water into an interlayer between the inner and outer drums within a specific time period of a final dehydration procedure of the washing machine; and with regard to different types of washing machines, the starting and ending times of water spraying are different. A water inlet of the electromagnetic water valve (6) is in communication with a tap water pipe. There are multiple water spray nozzles (5) arranged in order on a side face and a bottom face of the outer drum (2), and a water spray direction thereof faces the inner drum (3). The multiple water spray nozzles (5) are all connected to a water outlet of the electromagnetic water valve (6) and spray water under the control of the electromagnetic water valve (6) and the control circuit. By means of the simple additional device, water is sprayed into the interlayer between the inner and outer drums of the washing machine within a specific time period, and rinsing water and residual bubbles attached to the interlayer are rinsed off, such that dirt is prevented from accumulating in the interlayer, and the dirt accumulation problem existing in a fully-automatic washing machine is solved.
