Washing machine

Abstract

The invention discloses a washing machine, comprising a water inlet opening communicated with the water supply unit arranged outside the washing machine, a water supply opening communicated with the water inlet opening and a washing cylinder, and an impurity removing unit arranged between the water inlet opening and the water supply opening, and the impurity removing unit is used to remove the impurity in water. Arranged inside the impurity removing unit, a zeolite filter removes the impurity by filtering the water conveyed from the water inlet opening, and thus removes the metal ions in the water and reduces the rigidity of the water so as to gradually improve the water purifying performance.

Description

technical field [0001] The present invention relates to a washing machine. In particular, the present invention relates to a washing machine incorporating a water quality improving function in its water supply unit. Background technique [0002] It is well known that in any area where city water contains large amounts of metal elements such as iron, clothes washed with city water will be stained brown by iron elements. For this reason, in areas where urban water contains a large amount of iron, it is proposed to solve this problem by connecting a cartridge type water filtration unit to the faucet that supplies urban water to the washing machine and further supplying the water to the washing machine. The hose is connected to the water supply valve of the washing machine. [0003] In addition, various metal ions such as calcium, magnesium, copper, iron or chromium ions respectively affect the hardness of the city water with various adverse effects on the proper washing perfo...

Problems solved by technology

[0004] However, since most of said commercially available water filtration units are mainly designed to remove chlorine components, in areas where urban water contains a large amount of metal elements, when using any of these conventional water filtration units to supply water to washing machines , the cylinder of the water filter unit is easy to clog

In particular, where the water supply pressure is low, clogging of the cylinders seriously affects the water supply for the upper-floor occupants of high-rise buildings

Once the cylinder is too clogged, it is impossible to supply water to the washing machine within a predetermined time, thereby causing an error in the operation of supplying water to the washing machine, thus causing the user to be troubled by inconvenient operation

[0005] On the other hand, although the described method of mixing a synthetic zeolite builder with a detergent can remove many metal elements by absorption, metal ions instead cause metallic saponification of the surfactant in the detergent, thereby reducing the synthetic zeolite's ability to interact with the detergent. Proper Effect of Agent Mixing

In addition, since synthetic zeolite components are insoluble in water, when a large amount of synthetic zeolite is mixed with detergent, after the washing process is completed, fine particles of synthetic zeolite can always remain in the washed clothes, so it is not satisfactory as a problem to be solved finish washing clothes

[0006] In addition, in addition to the high cost of the ion exchange resin, for the structure provided in the washing machine disclosed in the patent publication, the special design and complicated structure of the washing machine further increase the manufacturing cost

Ion exchange resins are inconvenient to discard due to the high cost and also cause a lot of inconvenience to the user since the user has to frequently carry out the recycling process by adding sodium chloride
