Description

Chlorine Removal Device of Washing Machine

The present invention relates to a chlorine removal equipment washing machine, more particularly the chlorine component contained in the washing water or rinsing water before feeding the washing water or rinsing water into the washing tank ^- colored by removing the component (HOCl, OCl) It is to prevent the discoloration of 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 during a washing process, and rotatable 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 a water flow during the washing stroke, and a rotating 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 introduced into the washing tank together with the wash water when the water is supplied to the laundry administration, and connected to the lower side of the outer tank to be washed according to the opening of the drain valve (8). Expired discharging the waste water to the outside it consists of a drainage hose (9), and the like.

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 clothing, the color of the dye is missing and the decolorization by the detergent was insufficient, most of the bleaching was confirmed by the oxidizing power of the chlorine component contained in the 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 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 molecule, which produces the color of colored clothing, so that the color of clothing may be discolored.

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 component 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 component contained in the tap water to be volatilized into the air or the detergent is washed in the tap water. Dissolve the first and then wash the laundry into the detergent dissolved in the laundry, but in the case of the former is inefficient and cumbersome in terms of time and space utilization, the latter is cumbersome because you need to put the laundry after loosening the detergent In the rinsing process, since no detergent is added, 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 a complementary color of absorption due to the electron potential of the object due to the energy from the light source. If the chemical structure inside the object has a double bond or an unshared pair of electrons, it is in the visible range. In the chlorine state excited by energy, it is colored, but in the case of a single bond structure, the energy in the visible light region does not cause electron potential, so it is not colored.

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 dyes of colored clothes with double bond (π bond) structure to form a single bond (ρ bond). 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 preventing the phenomenon of changing the characteristics of the chromophore of the colored clothing by decomposing the chlorine component contained in the tap water by the flow of the neutralizing agent contained in the cartridge. The purpose is.

According to an aspect of the present invention for achieving the above object, the filter is formed on the bottom surface and the housing is formed with a connector and a discharge port for discharging the tap water from which the chlorine component is removed to the side of the washing tank, and the space is formed A cartridge fixed and installed in the housing, an inlet tube installed through the connector to penetrate the inside of the cartridge, a neutralizer in which the upper portion flows in the space as the tap water is introduced into the cartridge, and the inlet tube flows into the cartridge; Diffusion means for diffusing tap water supplied through all directions is provided, and a chlorine removing device of a washing machine is provided, which is composed of a cover coupled to a housing.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 3 to 6 as an embodiment.

3 is a longitudinal cross-sectional view showing an embodiment of the present invention, Figure 4 is a cross-sectional view taken along line A-A of Figure 3 and Figure 5 is a cross-sectional view showing another embodiment of the diffusion means, the present invention is a tap water in the housing 10 A connector 12a coupled to the supply path and a discharge port 10b for discharging the tap water from which chlorine is removed to the washing tank side are formed, and a space part 11 is formed inside the housing, and a filter 12 is formed on the bottom surface. Install the fixed cartridge (13).

The inlet pipe 14 through which tap water flows into the cartridge 13 through the connector 10a of the housing 10 is installed to penetrate through the inlet pipe 14. As it is introduced, the neutralizer 15 is contained so that the upper layer (about 1/5) flows in the space portion.

At this time, the neutralizer 15 contained in the space 11 should not be completely filled in the space.

This is to remove the chlorine component contained in the tap water while the upper portion of the neutralizer 15 flows in the space as the tap water flows into the space 11.

If the neutralizing agent 15 is filled in the space part 11, the neutralizing agent does not flow in the space part, and thus the inflow of tap water reacts only as it passes through the neutralizing agent. .

In addition, the passage cross-sectional area of the outlet 10b is set smaller than the passage cross-sectional area of the inflow pipe 14 through which tap water flows.

And the inlet pipe 14 may be formed long to contact the inner surface of the cover 16, or may be formed to extend only up to a considerable extent from the inner surface of the cover as shown in FIG.

This is to allow the tap water to be in contact with the neutralizer 15 for a longer time by allowing the tap water to be always filled in the space 11 so that a part of the neutralizing agent flows.

In addition, the inlet pipe 14 may be formed to extend in close proximity to the bottom of the cover 16, or may be formed to extend to a predetermined level from the bottom as shown in FIG. 6.

On the other hand, the cover 16 coupled to the housing 10 to close the upper portion is provided with a diffusion means for diffusing the tap water supplied through the inlet pipe 14 in all directions.

The diffusion means is fixed to the ball 17 on the bottom surface of the cover 16 located in the upper portion of the inlet pipe 14 as shown in Figure 3, or the cover located in the upper portion of the inlet pipe 14 as shown in FIG. The convex protrusions 18 are formed on the bottom of 16 to form a conical shape.

And the coupling part of the housing 10 and the cover 16 is fitted with an O-ring 19 for maintaining airtightness, and the cartridge 13 installed in the space 11 is detachably coupled to the cover 16.

3 and 5 show that the upper end of the cartridge 13 is fitted to the protrusion formed on the cover 16, Figure 6 shows that the upper end of the cartridge is screwed to the protrusion formed on the cover.

This allows the cartridge 13 to be simultaneously removed when the cover 16 is removed from the housing 10 in order to replace the neutralizing agent 15 contained in the cartridge 13 so that the neutralization capacity of the chlorine component is lowered and replaced. To provide.

3 and 5 show a state in which the upper end of the cartridge 13 is fitted to the protrusion formed in the cover 16, Figure 6 is a state in which the upper end of the cartridge 13 is screwed to the protrusion formed in the cover 16 Indicated.

Referring to the operation of the present invention configured as described above is as follows.

First, when water is started to perform a washing or rinsing stroke, tap water flows into the space 11 of the cartridge 13 through an inlet pipe 14 coupled to the connector 10a of the housing 10. Tap water flowing into the interior of the space 11 as it hits the ball 17 or the conical projection 18 formed in the cover 16 is introduced in a state diffused in all directions.

As such, when tap water flows into the space 11, the internal pressure is applied to the space because the flow path cross-sectional area of the outlet 10b is smaller than the flow path cross-sectional area of the inflow pipe 14, so that the tap water is completely different from the space.

As a result, some of the neutralizers 15 contained in the space 11 flow in the space.

That is, about 1/5 of the total height of the neutralizer 15 contained in the space 11 is floated and flows by the tap water filled in the space, so that the chlorine component contained in the tap water is primary to the neutralizer 11. The tap water is drained downward by its own weight in the neutralized state in contact with the water, thereby neutralizing the chlorine component secondaryly while passing through the neutralizer 11 of about 4/5 which does not flow.

Tap water neutralized by the chlorine component by the operation as described above is supplied to the washing tank side through the outlet (10b) formed in the housing 10 through the filter 12 fixed to the bottom surface of the cartridge 13 washing or rinsing administration Will be able to implement.

On the other hand, the neutralization capacity of the chlorine component decreases due to long-term use, and when the cover 16 is removed from the housing 10 to replace the cartridge 13, the cartridge 13 is detachably screwed or inserted into the cover. Since the cartridge is separated together with the cover 16, the replacement operation of the cartridge is simplified.

As described above, the present invention neutralizes the tap water supplied first by a neutralizing agent flowing in the space part, and then passes through a neutralizing agent that does not flow to neutralize the chlorine component secondarily, thus removing the chlorine component contained in the tap water. This is improved, and thus has a very economical advantage because it does not have to be expensive and laundered in the laundry to prevent discoloration of colored clothing.
