Description

Washing machine with washing water dechlorination unit to prevent discoloration of colored clothes

The present invention relates to a washing machine equipped with a washing water dechlorination apparatus for preventing discoloration of colored clothes. More specifically, the chlorine component contained in the washing water or the rinsing water supplied into the washing tank reacts with the chromophore of the reactive fiber on the water supply path. It is removed before reaching the washing tank to prevent discoloration of the colored clothing.

In general, a washing machine is a household appliance that removes various contaminants attached to clothes, bedding, etc. by using the emulsification of the detergent, friction action of the water flow due to the rotation of the pulsator, and the impact action of the pulsator on the laundry. Product.

In the conventional washing machine, as shown in FIG. 1, an outer case 9, an outer tub 10 installed in the outer casing 9 and filled with wash water therein, and installed inside the outer tub 10 to be washed and Washing tank 2 for performing dehydration, a pulsator 11 installed under the washing tank 2 to form water flow by stirring left and right, and a pulsator for generating a driving force to rotate the pulsator 11. The drive motor 12 is provided.

In addition, a water supply port 13 for supplying the wash water into the outer tub 10, a detergent input tank (7) for storing the detergent introduced into the washing tank (2) with the wash water at the time of water for the wash, Is connected to the lower side of the outer tank 10 is provided with a drain hose 15 for discharging the laundry wastewater to the outside in accordance with the action of the drain valve (14).

Therefore, in the conventional washing machine, when the user selects the washing course and turns on the operation button, the washing machine detects the amount and type of the laundry by the sensor and automatically sets the washing method. After watering up to an appropriate water level according to the type, washing is performed under the control of a microcomputer (not shown).

On the other hand, tap water supplied into the washing tank 2 and used as washing water or rinsing water is chlorinated for disinfection in a raw water state, and chlorine is volatilized into the atmosphere during the water purification process and supplied to each household, thereby naturally Although some are not removed, some remain in the water.

Therefore, when tap water is used as the wash water, there is a problem that discoloration of the colored clothing is caused by the chlorine component contained in the tap water used as the wash water.

In other words, the free chlorine contained in the tap water decomposes the chromophore molecules, which give off the color of colored clothing, resulting in the discoloration of the clothing, which may result in undesirable effects for the user.

On the other hand, in order to prevent the discoloration of clothing caused by the chlorine component of the tap water by receiving the tap water in a water tank of a certain capacity and leaving the lid open for a few days, the chlorine component contained in the tap water is volatilized to the atmosphere, or The detergent is first dissolved in the wash water, and the laundry is added to the wash water in which the detergent is dissolved.

However, the method of using tap water after leaving the tap water is inefficient and cumbersome in terms of time and space utilization, and the method of injecting laundry after removing the detergent is also difficult to apply.

Therefore, when washing using a washing machine, in order to prevent discoloration of colored clothing, dechlorination means for removing residual chlorine contained in the washing water supplied to the washing tank 2 is required. 2) Since there was no means for removing residual chlorine contained in the wash water supplied into the wash water, the discoloration of clothes by the chlorine component of the wash water was inevitable.

For reference, the principle of the color of the chlorine to discolor the colored clothing described in more detail as follows.

The color of an object is a phenomenon in which the object receives an energy from a light source and causes the electron potential of the object to become a complementary color of absorption. A structure having a double bond or an unshared electron pair in the chemical structure inside the object is visible in the visible range. Chlorine is excited by energy and colored, but the single bond structure cannot be colored because electron potential does not occur with energy in the visible region.

In other words, the chemical structure of a colored object has double bonds or non-covalent electron pairs, and these chemical structures are called chromophores or chromophores.

On the other hand, colored clothing having such a chromophore has a double bond (π bond) structure, and the free chlorine in the wash water reacts with the chromophore in the dye of the colored clothes to form a single bond (ρ bond) structure, thereby forming a chromophore. By changing its properties, it will not be colored.

The present invention is to solve the above problems, by allowing the chlorine component contained in the wash water or rinsing water supplied into the washing tank to be removed in advance before reaching the washing tank by reacting with the chromophore of the reactive fiber on the path to the water supply into the washing tank. It is an object of the present invention to provide a washing machine having a dechlorination device capable of preventing discoloration of colored clothes during washing or rinsing.

In order to achieve the above object, the present invention is to prevent the discoloration of colored clothing provided with a reactive fiber filter having a chromophore reacting with the free residual chlorine contained in the wash water on the wash water supply line between the water supply valve and the washing tank Washing machine with dechlorination system for washing.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 2 to 5.

First, Figure 2 is a block diagram showing the configuration of the water supply line of the present invention, Figure 3 is a perspective view showing a first embodiment of the present invention, washing water supply line connecting between the water supply valve (1) and the washing tank (2) On the flow path of (3), a reactive fiber filter 4 having a chromophore reacting with the free residual chlorine contained in the wash water is provided.

In this case, the reactive fiber filter 4 may be composed of only the reactive fiber (5), the plurality of disc-shaped reactive fibers (5) spaced apart along the flow path on the flow path of the wash water supply line (3) In addition, a net (6) (net) is provided between the reactive fibers (5).

In addition, the reactive fiber 5 and the net 6 is installed so that each side is perpendicular to the flow direction of the wash water.

The operation of the first embodiment of the present invention configured as described above is as follows.

First, the washing water flowing along the flow path of the washing water supply line 3 passes through the surface of the reactive fiber 5 installed to be perpendicular to the flow direction.

At this time, the chlorine component contained in the wash water reacts with the chromophore of the reactive fiber 5 to decolorize the reactive fiber 5.

That is, the chlorine component contained in the wash water is reduced by reacting with the chromophores of the reactive fibers 5 while sequentially passing through the plurality of reactive fibers 5 installed along the flow path direction.

Therefore, it is preferable to use colored natural fibers having hydrophilicity as the reactive fibers 5.
