Description

Washing machine with dechlorinating device

The removing and provided with a chlorine removal device for preventing the discoloration of colored clothing during washing ^- The present invention relates to a washing machine for washing laundry, more specifically a chlorine component (HOCℓ, OCℓ) contained in the tap water It is about a washing machine.

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

1 is a longitudinal cross-sectional view showing a structure of a general washing machine, a case 1 serving as a main body, an outer tub 2 installed in the casing and containing laundry and tap water during washing, and rotatably installed in the outer tub. And a washing tank 3 for washing and dehydrating, a pulsator 4 installed on the bottom surface of the washing tank so as to be left and right stirred to form a water stream during washing and rinsing, and the pulsator to be stirred. A driving motor 5 for applying rotational force, a water supply port 6 installed to be exposed to the outside of the case and supplying tap water to the inside of the tub according to the opening of a water supply valve (not shown), and the water supply port and It is installed so as to be installed through the detergent container (7) containing the detergent to be put into the washing tank together with the tap water at the time of water supply for the washing administration, and is connected to the lower side of the outer tank to complete the washing according to the opening of the drain valve (8) And a drain hose 9 for discharging the wastewater to the outside.

The washing machine configured as described above automatically selects the washing course in the state in which the user puts the laundry 10 for washing in the washing tank 3 and then turns on the operation button. Will be set.

Accordingly, after the tap water is supplied to an appropriate level according to the detected amount of laundry, the 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, there was a lack of dyes and discoloration due to detergent, and most of the discoloration was confirmed by the oxidation power of chlorine contained in tap water.

That is, the tap water supplied into the washing tank 3 and used as washing water or rinsing water is different from season to season for the purpose of preventing deterioration of water and suppressing breeding of bacteria in raw water, and chlorine is introduced.

When referring to domestic (Korea) water quality, the residual chlorine content is estimated to be 0.1 to 1.1 ppm in 1995, but the actual amount of chlorine is increasing due to deterioration of water quality. The input phenomenon is expected to intensify.

In this way, 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 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.

As a result, the discoloration of clothing increased in the order of blue, black, red, and green clothing.

For example, even if blue or red clothing is washed five times with tap water having a residual chlorine content of 0.1 ppm, discoloration that can be visually recognized occurs.

To prevent this, take the tap water in the tank and leave it for a few days with the lid of the tank open so that the chlorine component contained in the tap water is volatilized to the atmosphere, or the detergent is first dissolved in the wash water, which is tap water. It can be realized to some extent by reacting with the detergent to be neutralized and then washing by putting the laundry into the wash water in which the detergent is dissolved.

However, in the former case, inefficient and cumbersome in terms of time and space utilization, and in the latter case, since the laundry should be put in after washing the detergent, it is not cumbersome to perform discoloration of clothes.

Furthermore, since no detergent is added during the rinsing process, it is impossible to remove chlorine in the tap water that is introduced for rinsing, thereby further decolorizing clothes.

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

Figure 2 is a longitudinal sectional view showing a chlorine removal device applied to a conventional washing machine.

A first water supply valve 13 and a second water supply valve 14 installed at the first and second water supply ports 11 and 12 connected to the water cock (not shown) to control the water supply of the tap water; The second water supply valve 14 is installed on the inlet side of the tap water, the outlet 15 is formed on the bottom surface, the fabric softener cylinder 17 in which the fabric softener 16 is contained, and the inlet side of the tap water. The first water supply valve is installed in the guide to the flow of tap water flowing through the first water inlet, and on one side neutralizing agent dissolved water guide path (18) and the first and second outlets (19) (20) And a chlorine removal means 22 disposed above the tap water flow channel guide member to remove chlorine contained in tap water, and a lower portion of the tap water flow path guide member. It is installed in the detergent container 24, the detergent container 24 is contained therein, and the like.

The chlorine removal means 22 has a housing 28 having a tap water inlet 25 in the center and a space 26 and a discharge port 27 formed at the bottom thereof, and a space in the housing. A neutralizer cartridge 29 containing a neutralizer made of calcium sulfite, which neutralizes chlorine in the incoming tap water, which is seated, is detachably coupled to the upper part of the housing by screwing, and a tap water inlet 25 is formed on the bottom of the housing. Opening and closing to control the flow of tap water flows into the housing 28 is installed in the cap 31 and the lid 31 is formed with the projections (30a, 30b) for spreading the tap water discharged through the four directions The valve 32 etc. are comprised.

Therefore, when the first water supply valve 13 is opened by the mode set in the state in which the laundry 10 is introduced into the washing tank 3, the tap water flow path guide member 21 is provided through the first feed port 11. Flows into the interior.

As such, some of the tap water introduced into the tap water flow guide member 21 rises through the tap water inflow path 25 formed in the housing 28 to hit the bottom surface of the lid 31 and is evenly distributed in all directions. Into the space portion 26 of the housing 28 in a state of being in a state, the remaining portion of the tap water is guided to the bottom surface of the neutralizing agent dissolved water guide path 18 in the direction of the arrow ⇒, that is, the horizontal direction.

Accordingly, when some of the tap water introduced into the tap water flow channel guide member 21 is supplied to the housing 28 through the tap water inflow path 25, the protrusions 30a and 30b formed on the bottom surface of the lid 31 are provided. After the neutralizing agent is diffused into the space portion 26 embedded in the cartridge form and passes through the neutralizing cartridge 29, the neutralizing agent in the cartridge is dissolved by direct contact between the tap water and the neutralizing agent. It turns into neutralizing agent dissolved water containing the component.

The changed neutralizing agent dissolved water exits the neutralizing agent dissolved water guide path 18 of the tap water flow channel guide member 21 through the outlet 27 formed at the bottom of the housing 28, and then the bottom of the neutralizer dissolved water guide path. Taken out through the first outlet 19 formed on the surface is combined with the general tap water does not contain a neutralizing agent is converted into mixed water and then exits the detergent container 24 through the second outlet 20.

The mixed water introduced into the detergent container 24 is introduced into the washing tank through the inlet 33 together with the detergent 23 contained in the detergent container 24.

In the operation as described above, in the mixed water introduced into the washing tank together with the detergent, the chlorine component contained in the tap water reacts with the neutralizing agent to exist as a stabilized material.

When the chlorine component contained in the tap water is stabilized as described above, decolorization of laundry caused by the dyeing material and the active chlorine component reacts during the washing process of the laundry including the dyeing material in the washing tank.

That is, the chlorine component in the active state is already stabilized by reacting with the neutralizer component, so that the chlorine component to be combined with the chromophore of the dyeing material of the laundry is removed, thereby preventing the discoloration of the laundry.

However, these conventional devices have the following problems.

First, since the incoming tap water is in direct contact with the neutralizing agent of the chlorine removing means as a whole, the neutralizing agent in the cartridge is dissolved so that the neutralizing agent in the cartridge is excessively dissolved, and the life of the neutralizing cartridge 29 becomes very short. Lose.

Second, the neutralizing agent is excessively dissolved by the tap water flowing into the housing 28, so that the concentration of the neutralizing agent dissolved water becomes higher than necessary, which is uneconomical.

Third, because calcium sulfite mass is used as a neutralizing agent to convert chlorine into a stabilizing material, performance is easily deteriorated due to changes over time, and when tap water of low temperature is introduced, it reacts with chlorine due to temperature dependence of calcium sulfite This slows down the chlorine removal performance.

The present invention has been made to solve such a problem in the prior art, the neutralizing agent contained in the interior of the housing by the tap water is dissolved more than necessary, so that the consumption is increased, thereby preventing the phenomenon of shortening the neutralizer replenishment time due to that There is a purpose.

Another object of the present invention is to be able to visually identify the process in which the neutralizing agent in the housing is consumed to determine the time to replenish the neutralizing agent.

Still another object of the present invention is to allow a user to easily replenish the neutralizing agent when the neutralizing agent in the housing is consumed.

It is characterized in that the eluted due to the indirect contact by the tap water and the intermediate intermediary means to be introduced into the washing tank (3) with the tap water.

Intermediate means for indirect contact with the neutralizer 34 in the housing 35 through the water supply valve 63 is a neutralizer 34, one side is contained in the housing 35, the other part is osmotic pressure action The absorbing member 36 exposed on the tap water feed path is formed.

The absorbing member 36 may be applied to a non-woven fabric having a good hydrophilic property, but if the material is good hydrophilicity, it can be understood that various other types of materials can be used.

In the second aspect of the present invention, the housing 35 containing the neutralizing agent 34 is rotatably or detachably installed in the detergent container 7, and the neutralizing agent 34 contained in the housing is absorbed and dissolved by osmotic pressure. Absorbing member 36 to elute is installed to be exposed on the tap water feed path.

Removably install the housing (35) formed with a through hole (37) in the detergent container (7) located on the tap water feed path, and absorbs tap water flowing into the tap water feed path inside the housing. The absorbing member 36 is installed to expose a portion of the absorbing member 36 through the through hole 37 on the tap water feed path.

The interior of the housing 35 contains a neutralizer 34 that is dissolved as the tap water flowing along the tap water feed path is introduced into the housing by the absorbing member 36 and eluted onto the tap water feed path by osmotic pressure. Lose.

In order to increase the service life of the neutralizing agent 34 contained in the housing 35, the neutralizing agent is indirectly contacted by an intermediate medium (absorbing member) acting osmotic pressure to prevent unnecessary consumption of the neutralizing agent due to over-dissolution of the neutralizing agent. It was.

The absorbing member 36 having the above-mentioned role is installed to be exposed to the lower portion of the housing 35 and is in contact with the tap water flowing on the tap water transfer path, and the contact portion 36a for absorbing tap water into the housing 35. ), Which is integrally formed with the contact portion, is connected to the bottom surface of the housing 35, and as the tap water is absorbed into the housing through the contact portion 36a, the neutralizing agent is contacted with a portion of the neutralizing agent 34 to dissolve the osmosis agent. It consists of the melt | dissolution part 36b which elutes melted water to the contact part side by this.

4-12 show each Example of the 2nd form of this invention concretely.

FIG. 4 is a longitudinal sectional view showing a first embodiment of the second embodiment of the present invention, and FIG. 5 is an exploded perspective view showing the main parts of the first embodiment, wherein the front surface of the detergent container 7 detachably installed in the detergent container case 38 ( The seating part 39 is formed on the handle forming part to install the housing 35 in the seating part so as to be rotatable about both sides of the lower part.

The hinge hole 40 is formed on both sides of the seating part 39, and the hinge 41 is formed in the housing 35 by forming a hinge 41 inserted into the hinge hole so that the housing rotates around the hinge hole. The fitting of the housing 35 is completed by fitting into the hinge hole 40.

Accordingly, simply pressing the lower front face of the housing 35 as shown in the arrow direction of FIG. 7 rotates the housing 35 about the hinge 41 so that the opening of the housing is exposed to the outside. It becomes easy.

A locking means is provided on the connection surface of the detergent container 7 and the housing 35 to prevent the housing from being arbitrarily opened from the detergent container by the locking means.

As shown in the drawing, the locking means is provided with protrusions 42 formed on at least one side of the upper surfaces of both sides of the housing 35, and recessed grooves 43 are formed on the upper sides of the seating portions 39 to correspond to the protrusions. .

However, the locking means may be formed by forming a concave groove on at least one side of the upper surface of both sides of the housing 35 and a protrusion corresponding to the concave groove on the upper surface of the seating portion 39.

An extension piece 44 serving as a handle of the detergent container 7 is integrally formed in the lower portion of the front surface of the housing 35 configured as described above.

The reason for forming the extension piece 44 which serves as a handle on the lower part of the front surface of the housing 35 is that the housing and the housing by pulling the detergent container 7 and the extension piece 44 of the locked housing 35 by the locking means. This is to allow the detergent container to be drawn out from the detergent container case 38 at the same time so that detergent can be put into the detergent container 7.

Therefore, when the user puts the laundry to be washed in the washing tank 3 and selects a standard or colored course and then turns on the operation switch, the water supply valve 63 is opened so that the tap water supplied from the tap cock 45 is dispensed with the detergent container 7. It is introduced into the washing tank 3 together with the detergent.

The tap water flowing along the tap water transfer path formed between the detergent container 7 and the detergent container case 38 during the operation as described above is connected to the contact portion 36a of the absorbing member 36 exposed to the lower portion of the housing 35. As it comes in contact with the water in the direction of the arrow 46 shown in the dashed line in Figure 6, the tap water penetrates into the interior of the housing 35 by the capillary phenomenon.

As such, when the tap water absorbed into the housing 35 by the capillary phenomenon penetrates into the dissolving portion 36b of the absorbing member 36, the neutralizing agent 34 is in contact with the dissolving portion. Dissolve by

When the neutralizing agent 34 is dissolved by tap water absorbed into the housing 35 by the above-described operation, the neutralizing agent concentration of the site in contact with the dissolving unit 36b is increased to become the neutralizing agent dissolved water, thereby dissolving the neutralizing agent. The water moves to an exposed portion on the tap water feed path, which is a contact portion 36a having a low concentration of the neutralizer, by the osmotic pressure as shown by the arrow 47 shown by the solid line in FIG.

As such, when the high concentration of neutralizing agent dissolved water moves on the tap water transfer path, the neutralized water is included in the tap water because the incoming tap water contacts the contact portion 36a exposed on the tap water transfer path to wash off the neutralized dissolved water.

According to this operation, when the neutralized water dissolved in the neutralizing agent dissolved water moved to the contact portion 36a exposed through the tap water transfer path is washed out, the neutralizing agent concentration is lowered, and then dissolved in the dissolving part 36b to achieve the neutralizing agent concentration equilibrium. Since a high concentration of neutralizer component is moved toward the contact portion 36a exposed on the tap water transport path, the tap water injected into the washing tank 3 is always kept in a state in which a certain amount of neutralizer component is contained.

After the water supply is made to the selected water level by the operation as described above, the neutralizing component and the chlorine component contained in the tap water are neutralized to generate a chlorine component, which is generated according to the rotation of the pulsator 4 as in the prior art. The laundry administration will proceed by the heart flow.

Thus, neutralizing the chlorine component contained in the tap water by dissolving the neutralizing agent 34 without directly contacting the tap water flowing along the tap water transfer path with the neutralizing agent 34, thus decolorizing the laundry having the dyeing component. It will not cause.

After completion of the washing process, even when rinsing once and rinsing two times, the neutralizing water dissolved in the tap water is supplied in the same manner as described above to remove the chlorine component contained in the tap water.

However, the detergent is not contained in the detergent container 7 at the time of rinsing 1 time and 2 times of rinsing after completion | finish of a washing administration.

On the other hand, when the neutralizing agent 34 contained in the housing 35 is exhausted by long-term use, and to replenish the neutralizing agent, the opening of the housing is pressed only by pressing the extension piece 44 formed in the lower part of the front surface of the housing 35 in the direction of the arrow. Exposed to the outside.

In other words, the housing 35 is rotated about the hinge 41 as shown in FIG. 7, and only the extension piece 44 is pressed in the direction of the arrow so as to exit from the seating part 39. It is possible to easily replenish the neutralizing agent 34 in the 35.

After replenishing the neutralizing agent 34 in the housing 35, the upper side of the rotated housing 35 is pushed toward the seating portion 39, and the housing is locked to the detergent container 7 by the locking means.

FIG. 8 is for explaining a process of opening the detergent container 7 from the detergent container case 38 to inject detergent into the detergent container 7.

When the detergent container 7 and the housing 35 are integrated, and the detergent container 7 is to be separated from the detergent container case 38, the housing 35 is moved forward while the extension piece 44 serving as a handle is gripped. When pulled out as shown in FIG. 8, the detergent container 7 is opened from the detergent container case 38.

That is, while the housing 35 is installed in the detergent container 7 so as to rotate only in the clockwise direction with the hinge 41 formed at the lower portion thereof, when the housing 35 is pulled out, the housing 35 rotates in the counterclockwise direction. The force to be acted on, but the back of the housing 35 is in close contact with the detergent container (7), so that the housing 35 and the detergent container (7) are pulled at the same time, the detergent can be added.

9 is a longitudinal cross-sectional view showing a second embodiment of the second embodiment of the present invention, FIG. 10 is an exploded perspective view showing the main parts of the second embodiment, and FIG. 11 is a cross-sectional view showing a detergent container case.

In the second embodiment of the second embodiment, unlike the first embodiment, the upper part of the housing 35 is opened and closed by the lid 48, and the housing 35 is detachably installed in the detergent container 7.

That is, as shown in FIGS. 9 and 10, when the housing part 35 is seated on the detergent container 7, and the housing 39 is coupled to the housing part, the absorbing member 36 is connected to the detergent container 7. The through hole 39b is formed in the center of the seating portion 39a so as to be exposed to the lower portion.

In this case, as shown in Figure 11 on the bottom surface of the detergent container case 38, the guide piece 49 for guiding the portion of the tap water to move toward the absorbing member 36 exposed on the tap water transfer path inclined to form a detergent and The tap water moving together allows more contact with the absorbing member 36 exposed on the tap water feed path.

12 is a longitudinal cross-sectional view showing another fastening structure of the lid in the second embodiment, the fastening hole 50 is formed in the rear plate of the housing 35 and the locking jaw 51 is formed in the front plate of the lid 48. Insert one side of the fastening hole 50 and hook the hook 52 formed on the front to the locking jaw 51 to close the upper portion of the housing (35).

The bottom surface of the housing 35 is composed of an inclined surface 53 inclined downward toward the through hole 37, one surface is connected to the bottom surface and the other side is exposed on the tap water transfer path through the through hole 37 Absorbing member 36 is formed in the same shape as the bottom surface in close contact with the bottom surface.

In the case of the housing 35 and the absorbing member 36 as in the second embodiment, the area of the absorbing member 36 is increased in the housing 35 of the same size as in the first embodiment, thereby increasing the dissolution efficiency of the neutralizing agent. Has the advantage of being able to.

In the first embodiment of the second aspect, the housing 35 is made of a transparent material so that the inside of the housing can be visually identified without opening the housing.

This is to prevent the phenomenon of discoloration of colored clothing due to the visual identification of the amount of neutralizing agent contained in the housing and replenishing before the neutralizing agent is consumed so that washing is performed while the neutralizing agent is consumed.

However, in the second embodiment, since the housing 35 is detachably installed inside the detergent container 7, only the lid 48 is made of a transparent material.

Accordingly, even in the second embodiment, it is possible to visually identify whether the neutralizer 34 is consumed through the transparent lid 48 when the detergent container 7 is opened from the detergent container case 38 to inject detergent.

As described above, since the neutralizing agent is colorless when visually identifying whether the neutralizing agent 34 is consumed, if the absorbing member 36 to which the neutralizing agent contacts is colored, the consumption of the neutralizing agent 34 can be more easily identified.

The third and fourth aspects of the present invention are provided by separating the housing 35 from the detergent container 7.

13 to 17 show a third form, FIG. 13 is a longitudinal sectional view showing a third form of the present invention, and FIG. 14 is an exploded perspective view showing an embodiment of indirect melting means applied to the third form. 14 is a longitudinal cross-sectional view of the coupled state.

The tap water induction part 61 is formed such that a water supply valve 63 is installed at one side to guide the tap water into the tap water induction part, and the inlet port 55 of the housing 35 at the other side. The other end of the connecting pipe 65 is connected to form a discharge port 66 for discharging the tap water introduced through the water supply port 64 into the housing 35.

For reference, the water supply valve 63 applied to the third aspect of the present invention includes a passage (not shown) for guiding the tap water directly from the water pipe to the detergent container 7, and the water supply of the tap water induction part 61. Passages (not shown) are provided to guide the spheres 64, and it is recommended to use a double valve to control each passage.

18 is a longitudinal sectional view showing an embodiment of the tap water induction part in the fourth aspect, and FIG. 19 is a longitudinal sectional view showing another embodiment of the tap water induction part in the fourth aspect.

According to the opening of the water supply valve 63, the tap water flowing into the tap water induction unit 61 is branched to send a part to the housing 35 side, and the rest tap water induction unit 61 to be sent directly to the detergent container (7). And a take-out portion 67 to allow them to pass through between the and the detergent container (7).

The outlet portion 67 is a through-hole formed so that they penetrate each other at the portion where the tap water induction portion 61 and the detergent container 7 abut as shown in FIG. 18, or as shown in FIG. 19, the tap water induction unit 61 and the detergent container 7 as shown in FIG. 19. It may be a connecting member which is connected to one side which is in contact with each other, and allows them to penetrate each other.

The action according to the third and fourth aspects of the present invention will be described in more detail as follows.

When the user puts the laundry to be washed into the washing tank 3 and selects a standard or colored course, and turns on the operation switch, the passage through which the tap water induction part 61 and the passage are closed, and the water supply valve through the detergent container 7 Since the passage of the 63 is opened, the tap water supplied from the tap cock 45 flows into the detergent container 7, and the tap water is introduced into the washing tank 3 together with the detergent 23.

As such, the reason why the tap water to be introduced into the washing tank 3 during the water supply of the washing administration is directly supplied to the washing tank 3 without passing through the neutralizing agent indirect dissolution means side, which is the main part of the present invention. This is because the residual chlorine component contained in the tap water is neutralized by the neutralizing component in the detergent because the water is always introduced into the washing tank 3 together with the detergent in the detergent container (7).

Of course, it is understood that tap water may be supplied to the tap water induction part 61 side as in the second embodiment.

After the water supply of the water level set in the washing tank 3 is supplied, the washing valve 63, which was turned on, is closed and the washing stroke is performed in the same manner as the conventional one. The drainage of washing water proceeds.

In this way, since the washing cycle is performed, the mode is switched, so the first rinsing stroke is performed.

Therefore, when the water supply valve 63 is turned on for a set time for rinsing the laundry after washing is completed, the passage through the detergent container 7 is closed as opposed to the water supply of the washing stroke, and the tap water induction part 61 is closed. Since the passage of the water supply valve 63 is opened, the tap water supplied from the tap cock flows into the tap water induction part 61 through the feed port 64.

In the structure as shown in FIG. 13, the tap water introduced to the tap water induction part 61 is introduced into the housing 35 through the total amount of the connecting pipes 65, but in the structure as shown in FIG. 18 or FIG. Most of the tap water introduced into the water induction part 61 through the detergent container 7 through the through-hole or the connection member of the outlet part 67 provided to be through the detergent container 7 and into the inside of the washing tank 3 Is introduced, and only a part is introduced into the housing 35 through the connection pipe 65.

As such, when the tap water guided to the tap water induction part 61 is introduced into the housing 35 through the connecting pipe 65, the tap water introduced into the housing as in the second embodiment is absorber member supporting plate ( 58 is absorbed in contact with the contact portion 36a of the absorbing member 36 exposed downward, so as to permeate toward the dissolving portion 36b located in the space portion 54 by capillary action.

Thus, a part of tap water absorbed into the housing 35 by the capillary phenomenon of the contact portion 36a penetrates into the dissolving portion 36b to dissolve the neutralizing agent 34 in the form of granules or powder, and thus the dissolving portion 36b. The neutralizing agent concentration of the site close to is increased, whereby the neutralizing agent dissolved water is moved to the contact portion 36a side of the absorbing member 36 having a low concentration of the neutralizing agent by osmotic pressure to achieve a concentration balance.

In such a state, if the tap water continues to flow through the inlet 55 formed in the housing 35, the incoming tap water contacts the contact part 36a and washes away the neutralizing agent dissolved water moved to the contact part 36a. If the neutralizing agent concentration of the contact portion 36a is lowered due to the continuous inflow of tap water, the high concentration of neutralizing agent component in the dissolving portion 36b side is moved to the contacting portion 36a side to achieve the neutralizing agent concentration equilibrium again. It will always be in a state containing a certain amount of neutralizing component.

After passing through the housing 35 and entering the interior of the detergent container 7 with a certain amount of neutralizing agent contained in the tap water, the neutralizing agent is mixed with tap water flowing into the washing tank 3 by opening the water supply valve. Therefore, it serves to remove chlorine contained in tap water.

After the water supply is made to the selected water level by the operation as described above, since the water supply valve 63 is closed and the rinsing stroke is progressed by the heart current generated by the rotation of the pulsator 4 as in the prior art, the neutralizing component The chlorine component in the tap water is neutralized to remove the chlorine component.

As such, the tap water introduced through the inlet 55 of the housing 35 may dissolve the neutralizer 34 without directly contacting the neutralizer 34, and is introduced into the washing tank 3 and mixed with the chlorine in the tap water. The component and the neutralizing agent react with each other to convert into a stabilized state of chlorine so that it does not cause discoloration of the laundry with the dyeing component.

After performing the rinsing stroke once by the operation as described above, when performing the rinsing stroke twice, the water supply time of tap water supplied into the housing 35 is set longer than when rinsing once, and then rinsing twice Should be carried out.

The reason for this is that rinsing is performed once because high concentration of neutralizing agent dissolved water remains in the housing due to tap water flowing into the housing 35 during two rinsing cycles of pre-washing (washing performed before the current washing). At the time, a high concentration of neutralizing agent dissolved water is included in the tap water, but the concentration of the neutralizing agent in the housing 35 is lowered after the rinsing once.

Accordingly, in order to perform the rinsing cycle twice while maintaining the neutralizing agent concentration almost the same as when rinsing once, it is necessary to set a long time for supplying water to the inside of the housing.

The neutralizing agent 34 commonly applied in each form of the present invention, that is, the neutralizing agent contained in the housing 35 and dissolved in tap water absorbed into the housing 35 by the absorbing member 36 and eluted by osmotic action ( 34) It has little temperature dependence and uses sodium thiosulfate, which does not deteriorate with time, so that the reaction rate of chlorine and neutralizing agent occurs quickly even at low water temperature.

Particular consideration in the present invention is that since the neutralizing agent 34 is indirectly contacted with tap water, the neutralizing agent should not be used in the form of a lumped neutralizing agent as in the prior art.

Accordingly, in the present invention, it is preferable that the neutralizing agent 34 be granular or powdered sodium thiosulfate in each form.

The granular neutralizing agent 34 is indirect contact because the contact area with the tap water is maximized when dissolved in tap water absorbed into the housing 35 by the capillary phenomenon of the absorbing member 36 serving as an intermediate medium. Also facilitates dissolution of the neutralizing agent.

As described above, the fundamental technical idea of the present invention is to allow the tap water and the neutralizer 34 to be indirectly contacted by an intermediate medium. As an example, the absorbing member 36 using the natural law of osmotic pressure is provided. The various forms to which the was applied were shown through other examples.

Therefore, the present invention is not limited to the specific embodiments shown in the detailed description and the drawings, and includes the technical idea that the tap water and the neutralizer are indirectly contacted.

As described above, the present invention has the following advantages.

First, since the neutralizing agent 34 contained in the housing 35 is indirectly contacted with tap water, the neutralizing agent 34 can be prevented from being excessively dissolved more than necessary, thereby extending the life of the neutralizing agent.

Second, the use of sodium thiosulfate as a neutralizer to change the chlorine component into a stabilizing material prevents performance deterioration due to changes over time.

Third, even when low temperature tap water is introduced, the rate of reaction between the neutralizing agent and the chlorine component is increased, thereby improving the chlorine removal efficiency.
