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 a chlorine component (HOCl, OCl ⁻ ) contained in 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 by removing.

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 volatilized to some extent in the process of being supplied to the home, but some are not removed but remain dissolved 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 residual chlorine contained in the tap water decomposes the chromophore molecules that give off the color of colored clothing, thereby causing decolorization of the garment.

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, and since the detergent is not added during the rinsing process, the chlorine component in the tap water introduced for the rinsing cannot be removed, and thus discoloration cannot be prevented.

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, by the inert oxygen ion species generated in the photocatalyst to separate the chlorine component contained in the tap water in the ionic state to decompose the chromophore of the colored clothing The purpose is to prevent it.

Hereinafter, with reference to the accompanying Figures 3 to 11 showing an embodiment of the present invention in more detail as follows.

A feature of the present invention is to install a chlorine removal means (11) in which a photocatalyst, titanium dioxide (TiO ₂ ), which is a photocatalyst, causes a photoreaction to separate chlorine components on a water supply path of a washing machine.

The chlorine removal means 11 is installed only at the rear end of the cold water valve 12, as shown in FIG.

This is because the chlorine component is evaporated and removed when the tap water, which is wash water, is heated, so that the chlorine removing means 11 does not need to be installed on the hot water valve 13 side.

Figure 3 is a schematic diagram showing the configuration of the present invention, Figure 4 is a longitudinal sectional view showing a first embodiment of the present invention, Figure 11 is a block diagram showing the configuration of the water supply line of the present invention.

In the first embodiment of the present invention, the inlet port 14a and the outlet port 14b are formed in the tubular dechlorination tank 14 installed on the transport path of the wash water, and the inside of the dechlorination tank is irradiated with ultraviolet rays. A light source means 10, a titanium dioxide layer 15 that reacts with dissolved oxygen in the wash water by the light irradiated from the light source means to form an active ion species, and terminals 10a of the light source means at both ends of the dechlorination bath. It is composed of a sealing means for sealing both ends of the dechlorination tank (14) to expose.

The dechlorination tank 14 applied to the present invention can be molded into various shapes such as a cylinder or a polygon, so it is not particularly limited, but it is more preferable to form the cylinder in consideration of mass production.

The light source means 10 installed inside the dechlorination tank 14 to irradiate ultraviolet rays uses a lamp containing a lot of ultraviolet rays.

Mercury lamps, fluorescent lamps, halogen lamps can be used as the light source means 10, and black light lamps are effective.

The titanium dioxide layer 15 (15a), which reacts with dissolved oxygen in the wash water by the light irradiated from the light source means 10 to form an active ion species, is formed by coating the inner circumferential surface of the dechlorination tank 14 as shown in FIG. Or, irregularly formed on the outer circumferential surface of the light source means 10, or irregularly formed on the inner circumferential surface of the dechlorination tank 14 and the outer circumferential surface of the light source means 10 at the same time.

When the titanium dioxide layer 15 is irregularly formed on the outer circumferential surface of the light source means 10, it may be formed in a point shape as shown in FIG. 5 or in a band shape as shown in FIG. 6.

This is for the light of the light source means 10 is irradiated to the wash water through a portion where the titanium dioxide layer 15 is not coated to cause a photoreaction.

Sealing means for sealing both ends of the dechlorination tank 14 to expose the terminal 10a of the light source means to both ends of the dechlorination tank 14 is coupled to the flange (14c) formed on both ends of the dechlorination tank 14 by screwing. And a packing 17 positioned between the cap and the flange to prevent the wash water in the dechlorination tank 14 from leaking to the outside.

Accordingly, the washing water in the dechlorination tank 14 does not leak to the outside.

In the first embodiment of the present invention configured as described above, the titanium dioxide particles 18 may be placed in the dechlorination tank 14 to improve the removal performance of the chlorine component.

In this case, when the wash water flows into the dechlorination tank 14 through the inlet 14a, foreign substances contained in the wash water flow into the dechlorination tank and the dechlorination tank 14 through the outlet 14b. A filter 19, such as a sponge, should be provided to prevent the titanium dioxide particles 18 therein from being leaked out together with the wash water.

7 is a longitudinal sectional view showing a second embodiment of the present invention, and FIG. 8 is a longitudinal sectional view of a quartz tube applied to the present invention.

The second embodiment of the present invention differs from the first embodiment described above in that the quartz tube 20 is attached to the dechlorination tank 14 to the sealing means without directly fixing the light source means 10 to the dechlorination tank 14. After the fixing, the light source means 10 is detachably installed in the quartz tube 20.

This second embodiment of the present invention has the advantage that the replacement of the light source means is easier than the first embodiment when the light source means 10 is damaged, or is to be replaced.

Titanium dioxide layers 15 and 15a are formed on the inner circumferential surface of the dechlorination tank 14 as in the first embodiment by reacting with dissolved oxygen in the wash water by the light irradiated from the light source. It may be irregularly formed on the outer circumferential surface of the quartz tube 20 as shown in 8, or may be simultaneously formed on the inner circumferential surface of the dechlorination tank 14 and the outer circumferential surface of the quartz tube 20.

When the titanium dioxide layer 15a is formed on the outer circumferential surface of the quartz tube 20, it is formed in a point shape or a band like the same as when forming the outer circumferential surface of the light source means 10 of the first embodiment.

This is to allow the light of the light source means 10 to be irradiated to the wash water through a portion where the titanium dioxide layer 15a is not coated to cause a photoreaction.

9 is a longitudinal sectional view showing a third embodiment of the present invention, and FIG. 10 is a longitudinal sectional view showing a fourth embodiment of the present invention, in which the first and second embodiments and the components are the same.

However, if there is a part different from the first and second embodiments, the titanium dioxide layers 15 and 15a are not formed on the inner circumferential surface of the dechlorination tank 14 or on the outer circumferential surfaces of the light source means 10 and the quartz tube 20, and desalination is performed. The titanium dioxide particles 18 are put in the tank 14.

The titanium dioxide particles 18 contained in the dechlorination tank 14 are applicable in the form of powder or fine particles.

When the titanium dioxide particles 18 are applied in powder form, there is an advantage in that the contact with the chlorine component dissolved in the wash water is active, and the neutralization efficiency of the chlorine component is increased, but the service life is reduced.

On the other hand, when the titanium dioxide particles 18 are applied in the form of fine particles, the neutralization efficiency of the chlorine component is lowered because the contact with the chlorine component dissolved in the wash water is not active, as described above. Has the advantage of being extended.

Therefore, it is preferable to use powdered titanium dioxide particles 18 in the summer season when there are a lot of water-borne diseases and the amount of chlorine added is increased. On the contrary, it is preferable to use titanium dioxide particles in the form of fine particles in the winter season when the amount of chlorine is injected.

In each embodiment of the present invention, the dechlorination tank 14 is installed only at the rear end of the cold water valve 12 so that the light source means 10 for irradiating the washing water in the dechlorination tank with the cold water valve 12 is interlocked.

This is because the chlorine component is evaporated and removed when the tap water, which is wash water, is heated, so that the chlorine removing means does not need to be installed on the hot water valve 13 side.

Therefore, when the cold water valve 12 is opened in order to proceed with water supply for washing or rinsing in the state in which the present invention is installed as shown in FIGS. 3 and 11, the power source is also provided to the light source means 10 installed in the dechlorination tank 14. Since it is applied, the ultraviolet-ray is irradiated to the wash water in a dechlorination tank.

Accordingly, when the cold water introduced into the washing water supply line is introduced into the dechlorination tank through the inlet port 14a formed in the cold water valve 12 and the dechlorination tank 14, the ultraviolet light emitted from the light source means 10 is titanium dioxide. TiO ₂ is applied to layer 15, 15a or titanium dioxide particles 18 to convert TiO ₂ to Ti ^* O ₂ , whereby Ti ^* O ₂ reacts with dissolved oxygen (O ₂ ) to form active ion species ( O ^* ₂ ) to remove the chlorine components contained in the washing or rinsing water because the active ion species react with residual chlorine components to deactivate the activity.

Thus, the washing or rinsing water from which the chlorine component is removed is combined with the washing or rinsing water introduced into the detergent input tank through the water supply port 6 formed on the detergent input tank 7 and supplied into the washing tank 3, thereby providing the chlorine component. The removed washing or rinsing water can be used to perform washing or rinsing of colored clothing.

As described above, according to the present invention, before supplying the washing or rinsing water into the washing tank, in particular, before supplying the cold water containing chlorine to the washing tank, the chlorine component contained in the cold water is completely neutralized. The chlorine component contained in the rinsing water prevents the phenomenon of discoloration by reacting with the colored clothing. Therefore, it is very economical because the laundry is not required to be charged at a high cost in order to prevent the discoloration of the colored clothing. Has an advantage.
