Description
Technical field
The present invention relates to a kind of washing machine pre-filtering device, particularly related to a kind of filter for purifying water being arranged on washing machine inflow front end, for improving slurry, improving laundry washing effects to reach, making clothing have the effects such as longer service life.
Background technology
At present, the general using method of the washing machine that market is sold for directly running water is connected in washing machine by pipeline, for washing clothes etc.But there is following several material in running water, can have a negative impact to the cleaning of clothing:
The first, the hardness in running water is on the impact of laundry washing effects.Nearly all natural water, comprising well water, river, lake water, seawater is all hard water, and running water takes from reservoir or rivers, has only done precipitation and sterilization processing, is also hard water certainly.Hard water is not do not wash clean clothes, but can have influence on the consumption of detersive efficiency and washing agent.First, the CATION such as the calcium in hard water, magnesium with the anion electrical counteract in washing agent, can generate insoluble turbidity and precipitation and consume a large amount of detergent ingredients (washing powder, liquid detergent, soap etc.).The part washing agent not being neutralized precipitation is only had just cleaning function to occur.Therefore, this is a kind of wasting of resources.Secondly, the precipitation of generation, also can pollution clothes, causes dark clothes to whiten or adularescent soap scum stains; For light clothes, can cause burnt hair, jaundice because of soap scum precipitation again, whiteness is affected.
The second, in running water, chlorine residue is on the impact of clothes washing.Present stage, in general washing powder, liquid detergent, all containing enzyme component, for decomposing which water-fast spot, dirt, making it become DDGS and be removed, thus the neat and tidy that clothing is become.On the other hand, chlorine is topmost disinfectant in running water production process.Chlorine plays an important role in running water safety, has effectively contained that water body pathogenic bacteria are propagated, and prevents the diseases such as malaria, dysentery, typhoid fever from concentrating outburst.Therefore, the existence of chlorine residue is naturally had in running water.Chlorine residue can reduce the activity of the enzyme in washing powder, liquid detergent, reduces its solvability to spot, dirt, thus causes the situation of the non-wash clean of clothing.
3rd, the impact on clothes washing such as silt, iron rust, colloid in running water.Containing the silt, iron rust, colloid etc. that cannot remove completely in running water, these materials, once enter in washing machine, participate in the washing process of whole clothing, can impact the clean result of clothing, even can produce certain damage to clothing.
Summary of the invention
The present invention is directed to above-mentioned shortcoming, provide a kind ofly to change conveniently, washing machine pre-filtering device that effect is directly perceived, with low cost, effectively can remove the chlorine residue, silt, iron rust, colloid etc. in running water, and can effective softening of water and suppress the pre-filtering device of hard water fouling, reach and improve laundry washing effects.
Washing machine pre-filtering device, comprise main body, main body upper end is provided with water inlet, main body inner wall is provided with filter screen skeleton, and filter screen skeleton comprises the skeleton in hollow cylindrical and is positioned at skeleton skeleton top cover suitable for reading, is equipped with filter screen outside skeleton, filtrate is provided with in filter screen skeleton, skeleton top cover is by the sealing suitable for reading of skeleton, and skeleton is fixedly connected with skeleton top cover or is integrated, and has gap between skeleton and the sidewall of main body.Filtrate is generally the mixing filtrates such as active carbon, soften resin, zirconia, effectively can remove the chlorine residue in running water, can effectively softening of water or the fouling of suppression hard water.Running water flows into after main body and flows through filter screen, filter screen skeleton and filtrate successively, after the filtration of filter screen and filtrate, flow out body.In the space that the skeleton arranging sealing suitable for reading forces current to flow between skeleton and main body wall, increase effectively the contact area of current and filter screen, thus make filter screen and filtrate utilization ratio higher.
Skeleton top cover is provided with upper groove, is provided with sealing gasket in upper groove, and on the outer wall of skeleton, radial direction is provided with low groove, is provided with sealing ring in low groove, and sealing ring is between skeleton and filter screen.
Main body is provided with stud, and stud contacts with sealing gasket.
The end opening of skeleton is also provided with skeleton lower cover, covers and be provided with sieve aperture under skeleton.
Main body comprises upper cover and bottom, and bottom and upper cover thread connection, be provided with sealing ring between bottom and upper cover.
Bottom is provided with delivery port, and skeleton stretches in delivery port, is provided with sealing ring between skeleton and bottom.
Also comprise washing machine and the general water receiving pipe of washing machine, one end of the general water receiving pipe of washing machine is connected with running water pipe, and the other end is connected with the water inlet of main body, and bottom is provided with joint, and the joint of bottom is connected with the water inlet of washing machine.
Be provided with the second sealing gasket in joint, the second sealing gasket is used for the sealing between joint and the water inlet of washing machine.
The aperture of filter screen is between 170 order ~ 230 orders.Filter screen about 200 order apertures can effectively filter out silt in water, iron rust, colloid etc.
Filter screen is stainless steel filtering net.
The present invention is owing to have employed above technical scheme, there is significant technique effect: the present invention is easy to use, effect is directly perceived, with low cost, effectively can improve slurry, eliminate the hardness in running water, chlorine residue and the impact on clothes washing such as silt, iron rust, colloid, effectively improve laundry washing effects, and make clothing have longer service life.
