The case 14 is detachably attached in a drawer shape, and tap water from which residual free chlorine has been removed is supplied to the water tank when the filter case 14 is mounted.
[0006]
[Problems to be solved by the invention]
In the configuration described in Japanese Patent Laid-Open Nos. 02-136170 and 06-154474, all the water supply paths are completely switched to supply tap water from which residual free chlorine has been removed to the water tank. It is necessary to pass through the free chlorine removing material filled with the feed water and to apply water pressure to pass through the densely packed free chlorine removing material.
[0007]
Furthermore, in the cartridge system using a reducing agent, the reducing agent is mainly made of powdered calcium sulfite having a reducing action and granulated with water-soluble ethylcellulose or the like as a binder (binder). It was. As a result, the principle of the reaction mechanism is that the residual free chlorine comes into contact with the surface of the calcium sulfite granules and reacts.
[0008]
In addition, in the structure filled with granular material, it is easy to generate parts that are easy to pass water and parts that are difficult to pass, and when used with water pressure applied, the part that is easy to pass water has more residual release than other parts. Consumed to react with chlorine, a short pass was generated while leaving many active ingredients, and the residual free chlorine leaked out, resulting in a lifetime.
[0009]
In addition, in the cartridge using activated carbon, the flow rate decreases due to clogging by foreign substances contained in tap water, and the residual free chlorine gradually leaks because the flow velocity passing through the activated carbon increases and exceeds the adsorption capacity. Life is reached.
[0010]
In any case, since it is impossible for the user to know the lifetime from the outside, it is also required to predict and notify the lifetime based on the number of uses.
[0011]
Next, in the configuration described in Japanese Patent Application Laid-Open No. 06-238092, in order to supply tap water from which residual free chlorine has been removed into the aquarium, in the portion where the filter case containing the cartridge is mounted, In order to remove the residual free chlorine contained, a poorly soluble reducing agent is required to have high contact efficiency (wide contact area) with tap water. For this reason, the contact area gradually decreases during use, and similarly, it is impossible for the user to know the life from the outside. Therefore, it is also required to predict and notify the life from the number of times of use.
[0012]
In addition, it was impossible to supply a predetermined amount of reducing agent into the tap water from the washing process to the rinsing process with the solubilizing reducing agent. In order to cause discoloration of the colored pattern (dye) by the action, it is required to control the elution to a predetermined amount.
[0013]
The present invention disperses or dissolves a predetermined amount of a predetermined reducing agent in tap water or in a washing liquid, and removes the reducing agent and residual free chlorine by a complete and rapid oxidation-reduction reaction and is contained in tap water. The purpose is to prevent discoloration of colored patterns (dyes) due to the oxidation action of residual free chlorine, yellowing of silk, oxidation of various organic fiber surface treatment materials, and the like.
[0014]
The present invention solves the above-described problem, and elutes a substantially constant amount of reducing agent set in advance in the feed water, and tap water supplied in the water tank and in the water tank after the site where the reducing agent is disposed. The purpose is to remove the residual free chlorine completely and quickly and to make it possible to know the replacement or replenishment timing of the reducing agent.
[0015]
[Means for Solving the Problems]
In the washing machine of the present invention, a washing tub, a water supply valve for supplying tap water into the washing tub through a water supply path, and a particulate reducing agent for reducing free chlorine contained in tap water are gradually dissolved in water. And a storage case provided with a hole for storing the molded body and communicating inside and outside, the storage case being disposed in the middle of the water supply path , from the water supply valve By passing the tap water through the surface of the molded body in the storage case, the gradually soluble binder is dissolved in the water, and the reducing agent is dispersed and released in the tap water, together with the tap water in the washing tub. in which you configured so that is supplied to the.
[0016]
This eliminates the need to completely switch the water supply path or add water pressure to the cartridge as in the conventional example, and to remove residual free chlorine contained in tap water at the part where the filter case is attached. Without requiring high contact efficiency with tap water, a substantially constant amount of reducing agent set in advance is eluted in the feed water, and in the water tank in the middle of the water supply path after the site where the reducing agent is disposed. In addition, by generating a redox reaction with residual free chlorine contained in the supplied tap water, the residual free chlorine can be removed completely and quickly, and the user can also replace or replenish the reducing agent. It is easy to know.
[0017]
