Description
Technical field
The utility model relates to the washing machine field, and the filtration system of washing machine specifically especially a kind ofly prevents the washing machine drainage filtration system that foreign matter enters and the washing machine with this drain filtering system of domestic.
Background technology
The pulsator washing machine of prior art generally includes casing, is suspended on the outer barrel in casing, is provided with the interior bucket by the outer shaft driven rotary in outer barrel, and interior rotating shaft connects the agitator of bottom of the barrel; Be provided with draining valve in outer barrel bottom, the water inlet of draining valve is communicated with the water discharge outlet that outer barrel bottom is offered; The filter that common inner barrel wall is provided with, the current during by washing carry out passively the line bits and filter, and outer barrel bottom is provided with water pump, and the water inlet of water pump connects the discharge pipe line of outer barrel bottom, and the pipeline of washing machine inner tub is led in the water discharge outlet connection of water pump.Washing machine is when washing, and when the motor-driven agitator drove the clothing rotation, the water circulating pump running attracted the washings of outer barrel inner bottom part to flow back in interior bucket.Delivery port in the water pump connecting pipe is provided with filter, with the bits of the line in the filtration washing draining, foreign material, can flow back to interior bucket through the washings that filter, and reaches the effect of cleaning washings.This filter is generally soft filtering mesh bag or the filter frame of rigidity, and in use for some time, the line bits in filter, foreign material must manually take out clear, otherwise blocking filtering device and breed bacteria; In addition, can be wound around the water pump parts after entering water pump with the washings of wired bits, foreign material, if the harder foreign matters such as paper clip, hair fastener or coin easily cause water pump to break down; In addition, filter is arranged on exit of pump, can not prevents that foreign matter is to the infringement of water pump.
therefore, a lot of manufacturers make improvement to said structure, application number is that 200420120524.6 Chinese patent discloses a kind of interior circulating washing machine circulation line, comprise: the outer barrel water discharge outlet that is arranged on outer barrel bottom, be arranged on the outer barrel top, recirculated water after being used for filtering is sent into the interior loop exit that interior bucket reuses, be used for connecting the inner circulating tube of outer barrel water discharge outlet and interior loop exit, and be arranged between outer barrel water discharge outlet and interior loop exit, be used for the washings that the outer barrel water discharge outlet is discharged are pressed into again the internal circulation pump of interior bucket, at outer barrel bottom, the internal circulation pump input of inner loop pipeline arranges at least one and be used for to collect recirculated water velveteen and/or paper scrap, can be disassembled the filter that cleans.But this structure is comparatively complicated, and the improvement of inner loop pipeline is had relatively high expectations; In addition, be arranged on the inner loop pipeline of outer barrel bottom, cause the connection between filter and pipeline loosening with the outer barrel vibrations, easily make the poor filtration effect of filtering port, even cause the part foreign matter directly can not realize filtering fully the damage water pump by filter.
Application number is that 200610036929.5 Chinese patent discloses a kind of washing machine with water circulating pump, and it comprises the outer barrel that is suspended in casing, in outer barrel by the interior bucket of outer shaft driven rotary; Efflux out the drainage channel of the water in outer barrel to casing; The upstream of the water inlet of water pump is communicated with the outer barrel inner bottom part, and the downstream of its water discharge outlet connects the pipeline that leads to washing machine inner tub; The upstream of the water inlet of described water pump is provided with filter, and the filtering surface of this filter is positioned at described drainage channel, adjacent row water valve water inlet upstream.The long-time use of said structure easily makes line bits blocking filtering device.
In addition, with the rotary drum washing machine of draining pump, by the effect of draining pump, the water in washing machine is discharged, but all there is no effective filter, long-time use washing machine to have a large amount of foreign matters to enter in draining valve or draining pump, and the foreign matter that enters into valve or pump can't take out.May cause drainage arrangement waste water can't be discharged when foreign matter is serious, cause inconvenience to the user even economic loss.
In view of this spy proposes the utility model.
