Clothes washing equipment based on membrane-treatment water purification technology

Abstract

The invention discloses clothes washing equipment based on membrane-treatment water purification technology, comprising a casing, an outer tub and a washing tub, wherein the outer tub is arranged inside the casing, a containing cavity is formed between the outer tub and the casing, the washing tub is arranged inside the outer tub, the upper end of the washing tub is opening, a balance ring is arranged at the opening end, a drain outlet is arranged at the lower end of the washing tub, an impeller is arranged at the bottom of the washing tub, and is fixedly connected with an output shaft of a drive motor in the containing cavity, one end of a circulating tube is communicated with the drain outlet while the other end thereof is communicated with the upper end of the washing tub, a first drainvalve, a membrane filtration assembly and a drain pipe are arranged, from one end to the other end, of the circulating tube, one end of the drain pipe is communicated with the wall of the circulatingtube while the other end thereof extends out of the casing, a second drain valve is arranged on the drain pipe, and the membrane filtration assembly comprises a membrane filtration box and a high-pressure back flushing device. With the membrane filtration assembly arranged in the circulating tube, calcium ion, magnesium ion, fluoride ion and the like of circulating water can be removed, hardeningof clothes is avoided, and then, discomfort to people caused by the hardened clothes is avoided.

Description

technical field [0001] The invention relates to the technical field of laundry equipment, and more specifically relates to a laundry equipment with membrane treatment water purification technology. Background technique [0002] At present, there are various kinds of washing machines on the market, but the water source used for washing by the various kinds of washing machines is tap water. However, tap water in daily life is hard water, which contains cations such as calcium and magnesium, which will electrically neutralize with the anions in the detergent, forming insoluble turbidity and consuming a large amount of detergent components, only those that have not been neutralized and precipitated Only some detergents have the washing effect, so it causes a waste of resources; secondly, the precipitation that occurs will also pollute the clothes, causing dark clothes to whiten or have white soap scum stains, and for light-colored clothes, soap scum will precipitate At the same...

Problems solved by technology

However, tap water in daily life is hard water, which contains cations such as calcium and magnesium, which will electrically neutralize with the anions in the detergent, forming insoluble turbidity and consuming a large amount of detergent components, only those that have not been neutralized and precipitated Only some detergents have the washing effect, so it causes a waste of resources; secondly, the sediment that occurs will also pollute the clothes, causing dark clothes to whiten or have white soap scum stains, and for light-colored clothes, soap scum will precipitate At the same time, due to the presence of cations such as calcium and magnesium, they tend to be adsorbed on the clothes, which will make the clothes hard and uncomfortable to wear. The adhesion of calcium and magnesium ions to the clothes will cause dry and itchy skin, and some Steam Laundry Appliances Cause Scale to Clog Lines
