Abstract

The utility model relates to a washing machine capable of killing bacteria on clothes. The interior of an outer shell of a common washing machine is provided with a direct current electrolyser and a direct current stabilized power supply. The direct current stabilized power supply is connected with a power supply of the washing machine. When the washing machine works, the direct current stabilized power supply supplies direct current for the direct current electrolyser. After the water enters the direct current electrolyser from a water inlet pipe of the washing machine, the chloride ion (Cl [-]) of the water is electrolyzed, the hypochlorous acid (HClO) is generated in the water to kill the bacteria, and the hypochlorous acid (HClO) kills the bacteria on clothes after entering the washing machine. The utility model has the advantages of simple structure, and low cost.

Description

Washing machine capable of killing germs on clothes

The utility model relates to a washing machine, in particular to a washing machine which can kill bacteria attached to clothes. Is suitable for washing common clothes.

After the clothes are washed by a common washing machine, only dirt and oil stains are removed, and a plurality of harmful bacteria such as escherichia coli, staphylococcus aureus, natural bacteria and the like still exist, so that cross infection is easily caused, and the health ofpeople is harmed.

According to the domestic market of washing machines, most washing machines can only wash away dirt and oil stains but cannot kill bacteria on clothes. Only a few domestic appliance companies have introduced antibacterial washing machines and ozone sterilizing washing machines. Referring to the published technical data, the antibacterial washing machine adopts antibacterial plastics to make the impeller and the washing drum. The ozone sterilizing washing machine has ozone generator inside the casing to produce ozone to kill bacteria. The disadvantages of the two washing machines are: the antibacterial washing machine can only inhibit the propagation of bacteria on the impeller and the inner drum, but does not have any killing effect on the bacteria on the clothes which are not in contact with the antibacterial washing machine. The structure of the device for generating ozone for the ozone sterilization washing machine is complex and high in cost, and ozone overflowing from water can pollute air and harm human health.

The invention aims to provide an improved washing machine which can kill various bacteria attached to clothes while washing the clothes, does not pollute air and does not harm human health.

The invention is completed in the following way: the bleaching powder is added into tap water in the purification process of water plants to disinfect and sterilize. The bleaching powder mainly contains calcium hypochlorite [ Ca (ClO)]₂]The bactericidal substance is calcium hypochlorite [ Ca (ClO)]₂]Hydrolysis in water to hypochlorous acid (HClO), chemical equation: when the concentration of hypochlorous acid (HClO) in water reaches 1ppm, the bacteria in the water are killed. However, when the water reaches the home, hypochlorous acid (HClO) in the water is decomposed into chlorine ions (Cl) without sterilization ability^-). The invention installs a DC electrolysis device in the washing machine to remove chloride ions (Cl) in water^-) Hypochlorous acid (HClO) having bactericidal activity is regenerated by electrolysis. Chemical equation:

the overall reaction equation:

hypochlorous acid (HClO) is decomposed into chloride ions (Cl) again after killing bacteria^-) No pollution to environment. The present invention has a simple structure, and the number of parts and cost increase is small by adopting the structure to be described in detail below.

The invention will be described in further detail below with reference to the accompanying drawings.

FIG. 1: the detailed structure of the invention (with the top housing removed).

FIG. 2: top view of the present invention.

FIG. 3: fig. 2 is a partial sectional view of the washing machine taken along line a-a.

Referring to fig. 1 and 3: the direct current electrolysis device (2) and the direct current stabilized voltage power supply (3) are fixed on the top inside the shell (1) of the washing machine, and the direct current electrolysis device (2) is connected with a water inlet pipe (5) of the washing machine. The water outlet of the direct current electrolysis device (2) is communicated with a washing drum of the washingmachine. The direct current electrolysis device (2) shell is made into a cuboid shape by insulating materials, an electrolysis anode (7) and an electrolysis cathode (8) are arranged in the direct current electrolysis device (2), and both electrodes are formed by uniformly arranging a plurality of thin cylindrical metal rods in a staggered mode. The electrolysis positive electrode (7) and the electrolysis negative electrode (8) are correspondingly connected with the positive electrode and the negative electrode of the direct current stabilized power supply (3) through electric wires. The direct current stabilized power supply (3) is connected with a washing machine power supply (4). When clothes are washed, the direct current stabilized power supply (3) provides direct current for the direct current electrolysis device (2), water enters the direct current electrolysis device (2) from the water inlet pipe (5), original chloride ions (Cl-) in the water are electrolyzed by the direct current to generate hypochlorous acid (HClO) with sterilizing capability, and bacteria in the water and on the clothes are killed after the hypochlorous acid enters the washing machine.
