た。Conventional technology Conventionally, in this type of dehydrating and dehydrating washing machine, the general method for automatically adding fabric softener was to use the centrifugal force caused by dehydration to feed it into the washing tub. A fabric softener is added during dehydration just before rinsing, followed by water supply for a final rinse. In other words,
The rinse solution for the final rinse is initially an aqueous solution of fabric softener. However, while commercially available detergents are mostly anionic surfactants, fabric softeners are cationic surfactants, so they absorb the detergent that falls off from clothes during the final rinse. The anion of the activator reacts with the cation of the fabric softener in the liquid, reducing the absolute amount of the cationic activator in the fabric softener, which naturally reduces the amount of adsorption to the clothing, resulting in a sufficient softening effect. The problem was that there was no.

また最終すすぎがオーバーフローすすぎの場合、せっか
く入れた柔軟剤まで排出され、液かうすくなるので十分
な効果をえられない不便さもあった。Furthermore, when the final rinse is an overflow rinse, the softener that has been put in is also drained out, making the liquid thinner and less effective, which is inconvenient.

However, in the present invention, in the final rinse, after water is supplied to a high water level, rinsing is performed by stirring the rotary blade (3) for a predetermined period of time. Thereafter, the water is drained from a high water level (6) to a water level (7) where clothes are soaked, and the rinse liquid is drained to lower the water level. When this water level has fallen, a fabric softener injection device (8) is installed to inject a predetermined amount of fabric softener into the liquid, and the liquid and clothing (9) are stirred for a certain period of time by the stirring of the rotary blade (5). Ru. In this case, strong agitation is not required during washing and rinsing. The stirring time for the soft finish in the present invention may be about 3 minutes. After that, draining and dewatering are performed to complete the washing.

柔軟効果を得られるのである。Effects of the Invention As is clear from the above embodiments, the dehydrating and washing machine of the present invention performs rinsing with water for a predetermined period of time in the final rinse, then partially drains the water and then applies the fabric softener. Because of this, some of the detergent anions in the rinse solution are discharged and the absolute amount is reduced, and there is less reaction with the cations of the fabric softener, resulting in less loss of cation activator. In addition, the softening agent achieves a softening effect by sufficiently adsorbing the cationic active agent on the fiber surface, and the appropriate amount thereof is determined by its concentration relative to the fiber. For this reason, when the amount of water is large, the amount of cations that are dispersed in the water and not adsorbed to the fibers is also large, resulting in a large amount of loss, which requires a larger amount of flexibility. That is, in the present invention, by partially draining the water, the concentration of the solution is increased and a state is created in which the solution is easily adsorbed onto clothing. Furthermore, even when overflow rinsing is used for the final rinse, the overflow is sufficient at first, the water supply is stopped as part of the water is drained, and then the softener is added, so the softener does not flow out and the product is sufficiently softened. You can get the effect.

このように本発明の脱水兼用洗濯機は、洗濯による柔軟
仕上げ効果を大きく向上させるものである。As described above, the dehydrating and washing machine of the present invention greatly improves the softening effect of washing.
