Problems solved by technology

[0013] However, existing metal ion recovery methods are industrial methods
However, the wastewater discharged from the washing machine will be mixed with other wastewater discharged from households and wastewater discharged from other households, and the concentration of metal ions as target recyclables is low, so it is difficult to recover and reuse metal ions in the discharged water
Therefore, in order to recover the metal ions contained in the discharge water of household appliances such as washing machines, it is necessary to collect the washing discharge water of each household, and it is difficult to do this.

no. 1 Embodiment approach

[0055] First, the structure of the washing machine will be described.

[0056] figure 1 It is a vertical sectional view showing the overall structure of the washing machine. The washing machine 1 is a fully automatic washing machine.

[0057] Such as figure 1 As shown, the washing machine 1 has a housing 10 . The housing 10 has a rectangular parallelepiped shape and is formed of metal or synthetic resin, and its top and bottom surfaces form an opening. A top panel 11 made of synthetic resin is superimposed on the top opening of the casing 10, and the top panel 11 is fixed to the casing 10 by screws.

[0058] figure 1 Among them, let the left side be the front of the washing machine 1 and the right side be the back side. On the upper surface of the top panel 11 located on the back side of the washing machine 1, a rear panel 12 similarly made of synthetic resin is overlapped. Screws are fixed on the casing 10 or the top panel 11 . A base 13 made of synthetic resin is supe...

no. 2 Embodiment approach

[0133] Image 6 It is a figure which shows the schematic cross section of the drainage path of the washing machine which concerns on another embodiment of this invention. The washing machine 1 of the second embodiment has the same figure 1 The washing machine of the first embodiment shown has the same structure. In addition, in the washing machine 1, the control unit 80 of the washing machine 1 has a timer unit that measures the time from the start of drainage as the drain clogging detection device. The detection of whether the drainage is completed is carried out by the water level switch.

[0134] Such as Image 6As shown, there is a three-way valve 63 on the drain path of the washing machine, and the drain path is branched halfway through the three-way valve 63 into a first drain hose 601 as a first drain path with a metal ion recovery unit 200, and as a The drain water of the washing machine directly flows into the second drain hose 602 of the second drain path of the ...

no. 3 Embodiment approach

[0157] Figure 11 It is a figure which shows the general cross section of the washing machine which concerns on 3rd Embodiment of this invention. The washing machine is a washing machine with a non-perforated tub.

[0158] Such as Figure 11 As shown, the washing tub 30b has a peripheral wall in the shape of a taper that expands slowly upward. On the peripheral wall, there are no openings through which liquid passes, except for a plurality of dehydration holes 31 arranged in a ring at the uppermost portion. Even when water is accumulated in washing tub 30b for washing, rinsing, etc., water does not accumulate in the portion of outer tub 20b. In addition, when dehydration is performed, after most of the accumulated water is discharged, the water contained in the laundry rises along the peripheral wall of the washing tub 30b by rotating the washing tub, and is discharged to the outside from the uppermost dehydration hole 31. Inside barrel 20b.

[0159] In such a washing mac...

Abstract

A washing machine that allows recovery of metal ions fed into water used in washing. The washing machine (1) includes metal ion water generating means (90) for adding metal ions to water; and metal ion recovering unit (200) for recovering metal ions from the water, disposed so as to be in contact with the water having metal ions added thereto by the metal ion water generating means (90). In the method of recovering metal ions in the washing machine (1), metal ions are recovered from the water by, in the washing machine (1) capable of applying metal ions to a fiber structure, disposing the metal ion recovering unit (200) so as to be in contact with the water used in washing.

Description

technical field [0001] The present invention relates generally to washing machines, and more particularly to washing machines capable of applying metal ions to fibrous structures. Background technique [0002] When washing in a washing machine, a finishing agent is often added to the water, especially the rinse water. As a general finishing substance, a softening agent, a sizing agent, etc. are mentioned. In recent years, in addition to the above-mentioned finishing substances, there has been a washing machine in which metal ions (such as silver ions) can be applied to the fiber structure as a finishing substance in order to impart antibacterial and deodorizing properties to the fiber structure. [0003] Japanese Unexamined Patent Publication No. 2004-24597 (Patent Document 1) describes a washing machine in which metal ions and a softening agent are applied as finishing substances. On the other hand, JP-A-2004-33996 (Patent Document 2) describes a washing machine capable o...
