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 in order to solve such a problem in the prior art, by forming a fluidized bed to flow the neutralizing agent in the cartridge to neutralize the chlorine component contained in the tap water while the neutralizing agent flows by tap water supplied from the lower portion of the neutralizing agent The purpose of this is to prevent the phenomenon of changing the characteristics of the chromophore of colored clothing.

According to a first aspect of the present invention for achieving the above object, in the chlorine removal device for removing the chlorine component in the water by filling a neutralizing agent therein, the inlet for installing the tap water to the inlet for inflow of tap water and And a neutralizing agent flow means, which serves to improve the contact between the introduced tap water and the neutralizing agent by flowing the filled neutralizing agent with the introduced tap water to discharge the tap water from which the chlorine component is removed. Chlorine removal device of the washing machine is provided.

According to the second aspect of the present invention, there is a housing formed with a connector coupled to the supply path of tap water and a discharge port for discharging tap water from which chlorine is removed to the washing tank side, and a tap water inlet filter is fixed to the bottom and a filter is fixed to the upper side.

Hereinafter, with reference to Figures 3 to 5 showing an embodiment of the present invention in more detail as follows.

Figure 3 is a longitudinal cross-sectional view showing a first embodiment of the present invention, the present invention forms a connector (10a) coupled to the supply path of the tap water in the housing 10, the tap water from which the chlorine component is removed on both sides of the connector It forms a discharge port (10b) for discharging to the washing tank side.

The plurality of tap water inflow filters 11a are fixed to the bottom surface of the cartridge 11 having the space 11c, and the filter 11b for overflowing the tap water from which chlorine is removed is moved to the outlet 10b side. This is installed inside the housing 10.

At this time, between the bottom of the cartridge 11 and the housing 10 is formed a diffusion chamber 12 for diffusing the incoming tap water, and the inlet pipe 13 penetrating the diffusion chamber 12 in the connector (10a) Install.

This is to allow the tap water introduced through the inflow pipe 13 to flow into the space 11c of the cartridge 11 in a uniform state.

It is more preferable to install the net 14 on the inlet pipe 13 to prevent foreign substances contained in the tap water from flowing into the housing 10 during water supply.

In addition, the space 11c of the cartridge 11 contains a neutralizing agent 15 for neutralizing the chlorine component contained in the tap water while the whole flows as the tap water flows in through the inlet pipe 13. ) Is not filled in the space to flow by tap water.

The diaphragm 16 which partitions the fluidized bed formed in the said cartridge 11 can be fixed in the space part 11c so that it may be located in the lower part of the filter 11b.

This applies when it is necessary to limit the range in which the neutralizing agent flows according to the amount of the neutralizing agent 15 contained in the space 11c.

As described above, the lid 17 is coupled to the housing 10 in which the cartridge 11 is installed to close the upper portion.

The O-ring 18 is fitted to the coupling portion of the housing 10 and the cover 17 so as to prevent leakage from occurring through the coupling portion thereof.

In addition, a protrusion frame 17a is formed on the bottom surface of the cover 17 so that the inner peripheral surface of the protrusion frame 17a is fitted to the outer peripheral surface of the cartridge 11, or the cartridge 11 on the outer peripheral surface of the protrusion frame 17a. The inner circumferential surface is fitted to be combined.

This is to facilitate the replacement operation by removing the cover 17 from the housing 10 to replace the cartridge 11 so that the cartridge is separated with the cover.

4 is a longitudinal sectional view showing a second embodiment of the present invention, which is different from the above-described first embodiment, in which the inlet pipe is installed separately from the diffusion chamber 12 and is not separately installed, and is combined with the supply path of the tap water. The connector 10a is configured to act as an inlet pipe.

In the second embodiment, the description of the same parts as those of the first embodiment described above is omitted, and the same reference numerals are used.

FIG. 5 is a longitudinal sectional view showing a third embodiment of the present invention. In the above-described first and second embodiments, the tap water supplied from the bottom of the housing 10 is overflowed in the cartridge and the housing 10 is again flown. The third embodiment differs only in that the tap water supplied from the top of the lid 17 is configured to be overflowed from the cartridge 11 and discharged to the bottom of the housing 10.

In the third embodiment, the description of the same parts as those in the first and second embodiments is omitted, and the same reference numerals are used.

When the cartridge 11 is installed in the housing in a state where only the discharge port 10b for discharging the tap water from which the chlorine component is removed is discharged to the washing tank side, the discharge path is formed between the housing 10 and the cartridge 11. Let (19) be formed.

In addition, the cover 17 detachably coupled to the housing 10 forms a connector 10a connected to the supply path of the tap water, and the connector has an inlet pipe extending to a portion proximate to the bottom surface of the cartridge 11. 17b are formed to pass through each other.

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

First, in case of the first and second embodiments of the present invention, when water is started to perform washing or rinsing stroke, the tap water serves as an inlet pipe 13 or inlet pipe coupled to the connector 10a of the housing 10. It is introduced into the diffusion chamber 12 formed between the cartridge 11 and the housing 10 through the connector (10a) formed integrally with the dispersed in all directions to maintain a uniform pressure.

When the tap water introduced in this state flows into the space portion 11c side of the cartridge 11 through the tap water inflow filter 11a fixed to the bottom surface of the cartridge 11, the neutralizer 15 contained in the cartridge floats in the space portion. Therefore, the neutralizing agent flows in the space by tap water into which the neutralizer is introduced, thereby contacting the tap water for a relatively long time to neutralize the chlorine component contained in the tap water.

After the chlorine component contained in the tap water is neutralized by the operation as described above, the tap water is overflowed through the filter 11b fixed to the upper side of the cartridge 11 to the washing tank side through the outlet 10b formed in the housing 10. Since it is supplied, the washing or rinsing stroke can be performed.

In the third embodiment of the present invention, when water is started to perform washing or rinsing stroke, tap water is integrally formed in the cover 17 to extend the inlet pipe 17b extending to the bottom of the cartridge 11. Through the inside of the cartridge.

As such, the tap water introduced into the cartridge is blocked as shown in FIG. 5 unlike the first and second embodiments in which the bottom surface of the cartridge 11 is fixed with the tap water inflow filter 11a. Since the neutralizing agent (15) contained in the cartridge is diffused to the upper side of the space part by the diffusion of the neutralizing agent (15), it flows in the space part (11c) by the tap water into which the neutralizing agent flows and is included in the tap water by being in contact with the tap water for a relatively long time. Neutralize chlorine.

Tap water in which chlorine is decomposed by the above-described operation passes through a filter 11b fixed to an upper side of the cartridge 11, and a discharge passage 19 and an outlet 10b formed between the housing 10 and the cartridge 11. Since it is supplied to the washing tank side will be able to perform the washing or rinsing stroke.

On the other hand, in each embodiment of the present invention, if the cartridge 11 containing the neutralizing agent 15 is used for a long time, the neutralization capacity of the chlorine component is lowered, so it must be replaced with a new cartridge.

To this end, when the cover 17 is removed from the housing 10, the cartridge 11 is detachably fitted to the cover, so that the cartridge is separated together with the cover 17, thereby simplifying the replacement of the cartridge.

As described above, the present invention is to neutralize the chlorine components and delay the contact time by the neutralizer flowing in the space portion to supply the tap water to be supplied to the inside of the washing tank, so that the removal efficiency of the chlorine components contained in the tap water is improved. Therefore, to prevent the discoloration of colored clothing, it is very economical because it does not have to pay a lot of laundry to the laundry.
