Description

Washing machine equipped with color preventing device for colored clothes

The present invention relates to a washing machine equipped with a decoloration preventing device for colored clothing, and more specifically, to remove chlorine (Cl ₂ ) contained in the washing water or rinsing water before washing water or rinsing water is supplied into the washing tank. It is to prevent the discoloration of colored clothing.

In general, a washing machine for washing clothes and bedding, etc. is used for various contaminants attached to clothes, bedding, etc. by using the emulsification of the detergent, friction action of the water caused by rotation of the washing blade, and impact on the laundry. It is a home appliance to remove.

1 is a longitudinal sectional view schematically showing a conventional washing machine, a case 1 serving as a main body, an outer tub 2 installed in the casing and containing laundry and washing water when the laundry is in progress, and rotatably in the outer tub; A washing tank 3 installed to perform washing and dehydrating stroke, a pulsator 4 installed on the bottom surface of the washing tank so as to be stirred and forming water flow during the washing stroke, and a rotational force to stir the pulsator A driving motor 5 for applying a water supply, a water supply port 6 installed to be exposed to the outside of the case and supplying the wash water to the inside of the tub according to the opening of a water supply valve (not shown), and through the water supply port. A detergent inlet tank (7) for storing detergent so as to be put into the washing tank together with the wash water when the water is supplied to the washing administration and connected to the lower side of the outer tank to be washed according to the opening of the drain valve (8) It is composed of a drain hose (9) for discharging the waste water to the outside.

The washing machine configured as described above automatically selects the washing course while the user puts the laundry for washing in the washing tank 3 and then turns on the operation button. Therefore, after washing the water to an appropriate level according to the amount of laundry, washing administration is performed under the control of the microcomputer (not shown).

In the case of washing colored clothes using such a washing machine, consumers have until now recognized the discoloration of colored clothes as the dye itself or the discoloration by detergent.

However, due to the development of the dyeing industry for clothes, the color of the dye is missing and the decolorization by detergents was inadequate, and most of the discoloration was confirmed by the oxidizing power of chlorine contained in tap water.

In other words, the tap water supplied into the washing tank 3 and used as washing water or rinsing water has a seasonal difference for disinfection in a raw water state, but chlorine is introduced.

The chlorine introduced into the raw water is removed to some extent by volatilization in the water purification process and the process of supplying to the home, but some are not removed but remain in the dissolved state in the water.

When washing is performed using such tap water, the colored clothing is discolored by the chlorine component contained in the tap water.

This is because the free chlorine contained in the tap water decomposes the chromophore molecule, which produces the color of colored clothing, so that decolorization of clothing occurs.

As a result, the discoloration of clothing was found to increase in the order of blue, black, red and green clothing.

Accordingly, in order to prevent discoloration of clothing by the chlorine content contained in the tap water, the tap water is received in the water tank and left for a few days with the lid open to allow the chlorine content contained in the tap water to be volatilized into the air or in the tap water. Dissolve the detergent first, and then wash the laundry by dissolving the detergent, but in the case of the former, it is inefficient and cumbersome in terms of time and space utilization, and in the latter case, after washing the detergent, the laundry must be put in after the detergent is dissolved. The situation is not cumbersome.

Therefore, in order to prevent discoloration when washing colored clothes using a washing machine, it is preferable to completely remove residual chlorine components contained in the wash water before supplying the wash water to the washing tank 3.

For reference, the principle of discoloring colored clothing by the chlorine component will be described in detail as follows.

The color of an object is the complementary color of the absorption color due to the electron potential of the object due to the energy from the light source. The chemical structure inside the object has a visible region in the case of a double bond or an unshared electron pair. The chlorine state is excited by the energy in the interior and is colored. However, in the case of a single bond structure, the energy in the visible light region does not cause an electron potential, and therefore does not have a color.

In the chemical structure of an object that becomes colored in the chlorine state excited by energy in the visible light region, it has double bonds or unshared electron pairs, which are called chromophores or chromophores.

Colored garments with chromophores have a double bond (π bond) structure, so that free residual chlorine contained in the wash water reacts with chromophores in the dyes of colored clothes with double bond (π bond) structure. By forming the structure, the characteristics of the chromophore are changed, and accordingly, the colored clothing cannot gradually take on color.

The present invention has been made to solve such a problem in the prior art, chlorine contained in the tap water by using energy to excite, ionize, and electrolyze a gas atom or molecule through active thermal motion of electrons in a plasma. The purpose is to prevent the decomposition of chromophores of colored clothing by decomposing components.

According to a first aspect of the present invention for achieving the above object, a washing machine provided with a discoloration preventing device for colored clothing provided on the water supply path of the washing machine is a chlorine removing means for decomposing chlorine by a chemical reaction according to the plasma generation in the washing water Is provided.

There is provided a washing machine having a discoloration preventing device for colored clothing composed of a power supply unit for applying a high voltage to form a plasma.

There is provided a washing machine including a probe exposed on a water supply path of a tap water, and a discoloration preventing device for colored clothing composed of a power source for applying a high voltage to the electrode and the probe to form a plasma.

FIG. 5 is a perspective view showing a second embodiment of the present invention, in which a myriad of granular chlorine removers 18 are filled to extend the tap water flow path between the electrodes 15a and 15b in the same configuration as the first embodiment. will be.

The particulate chlorine remover 18 may be selected from an appropriate type of activated carbon, a neutralizer, or a ceramic.

In the second embodiment described above, when the tap water passes between the electrodes 15a and 15b, the cross-sectional area of the flow path is reduced by the granular chlorine remover 18 filled therebetween, so that the contact time between the tap water and the plasma is delayed.

That is, the movement of the tap water and the plasma moving in opposite directions becomes curved by the granular chlorine remover 18, thereby increasing their contact time (reaction), thereby increasing the removal efficiency of the chlorine component.

Therefore, when the cold water valve 12 on the tap water supply path is opened and high voltage is applied to each of the electrodes 15a and 15b in the state where the cold water flows, the probe 10 fixed to the electrode 15a on one side is provided. Since plasma in the state where ions are decomposed toward the opposite electrode 15b in the above is generated, the mechanism is decomposed by highly reactive species such as hydrogen peroxide, ozone, and OH radicals generated by reaction with tap water passing between them. Chlorine content in tap water is decomposed.

6 is a cross-sectional view showing a third embodiment of the present invention, FIG. 7 is a cross-sectional view taken along the line AA of FIG. 6, and FIG. 8 is a longitudinal cross-sectional view showing another embodiment of the electrode.

According to a third embodiment of the present invention, a pair of supports 14a and 14b are provided so that tap water can pass through a tap water supply path, electrodes 19 fixed to the respective supports, and both ends of which are fixed to the support. Probe 10, and a power supply unit 16 for applying a high voltage to the electrode and the probe to form a plasma.

Similarly to the first embodiment, since the third embodiment of the present invention does not contain chlorine, hot water is installed only at the rear end of the cold water valve 12 as shown in FIG.

In addition, in order to prevent safety accidents due to the voltage applied during operation, the power supply unit 16 is connected to the ground line to ground.

Compared to the first and second embodiments, the third embodiment of the above-described structure has an advantage of generating the same amount of plasma even when a small voltage is applied.

This is because the distance between the electrode 19 and the probe 10 is closer than that of the first and second embodiments.

Although one probe 10 fixed to the supports 14a and 14b is shown in the present invention, a plurality of probes 10 may be fixed to the support to increase efficiency.

In addition, the electrode 19 to which the voltage is applied may be formed in a cylindrical shape as shown in FIGS. 6 and 7, or may be formed in a U-shaped cross section as shown in FIG. 8.

In the third embodiment, like the second embodiment, the granular chlorine removing agent 18 of any one of activated carbon, neutralizer and ceramic may be incorporated between the supports 14a and 14b.

Therefore, when a high voltage is applied to each electrode 19 and the probe 10 in the state in which the cold water flows by opening the cold water valve 12 on the tap water supply path, respectively, it is fixed between the supports 14a and 14b. Since the plasma of the ion is decomposed from the probe 10 to the cylindrical electrode 19 side is generated, the highly reactive species such as hydrogen peroxide, ozone, OH radicals, etc. generated by the reaction with the tap water passing therebetween Depending on the decomposition mechanism, chlorine in the tap water is decomposed.

FIG. 9 is a sectional view showing a fourth embodiment of the present invention, FIG. 10 is a sectional view taken along the line BB of FIG. 9, and FIG. 11 is a longitudinal sectional view showing another embodiment of the electrode.

In a fourth embodiment of the present invention, a pair of supports 14a and 14b are provided so that tap water can pass through a tap water supply path, electrodes 19 fixed to the respective supports, and are positioned to face the electrodes. It is composed of a probe 10 fixed to the electrode cylinder 20, one end of which is exposed on the water supply path of the tap water, and a power supply unit 16 for applying a high voltage to the electrode and the probe to form a plasma.

Similar to the above-described embodiments, the fourth embodiment of the present invention is installed only at the rear end of the cold water valve 12, which is a supply path of cold water containing chlorine, and is connected to the power supply unit 16 in order to prevent occurrence of safety accidents. 17) Connect to ground.

The electrode 19 applied to the fourth embodiment may be formed in a cylindrical shape as shown in FIGS. 9 and 10, or may be formed so that the cross section is U-shaped as shown in FIG. 10.

In the case of FIG. 11, the electrode cylinder 20 to which the probe 10 is fixed is fixed to the cover 21.

In FIG. 11, in order to increase the removal efficiency of the chlorine component contained in the tap water, a plurality of electrode cylinders 20 to which the probes 10 are fixed are fixed to the electrodes 19, and the probes 10 are respectively fixed. It is fixed to the electrode barrel 20 to be perpendicular to the supply direction of the tap water.

However, the number of electrode cylinders 20 fixed to the electrodes 19 is not necessarily limited.

This is because the amount of plasma generated may be reduced according to the capacity or water pressure of the washing machine, or only one electrode cylinder 20 in which the probe 10 is built in may be installed according to the voltage applied to the probe 10. to be.

The probe 10 is formed to narrow the end of the electrode cylinder 20 is installed to be exposed downward, this is to improve the efficiency by concentrating the plasma generated from the probe (10).

In addition, the air nozzle 22 is connected to supply compressed air to the inside of the electrode cylinder 20 in order to further increase the generation efficiency of the plasma.

Accordingly, the electron movement of the plasma generated by the probe 10 is promoted in accordance with the flow of compressed air.

On the other hand, the granular chlorine remover 18 of any one of activated carbon, a neutralizer, and a ceramic is embedded between the supports 14a and 14b as in the second and third embodiments.

The electrodes 15a, 15b, 19 applied to each embodiment of the present invention are preferably formed of a gold mesh with good conductivity, wherein the electrodes 15a, 15b, 19 and the supports 14a, 14b are used. Should be reticulated to allow tap water to pass through.

Therefore, when the cold water valve 12 on the tap water supply path is opened and high voltage is applied to the probe 10 fixed in the electrode 19 and the electrode 20 in the state where the cold water flows, the support 14a is respectively supported. Plasma in which ions are decomposed to the electrode 19 from the probe 10 which is fixed in the electrode cylinder 20 fixed between the holes 14b and exposed downward is generated.

At this time, since the lower portion of the electrode cylinder 20 is formed narrowly, the movement of the generated plasma is promoted and acts strongly on the tap water passing through.

When the compressed air is injected through the air nozzle 22 in the above operation, the efficiency is maximized.

Accordingly, the chlorine component in the tap water is decomposed by a mechanism that is decomposed by highly reactive species such as hydrogen peroxide, ozone, and OH radicals generated by the reaction with the tap water passing therebetween.
