  The washing / dehydrating shaft 46 is hollow and has a biaxial structure, and the rotation of the washing / dehydrating shaft 46 is switched by a reduction gear and a clutch (not shown) inside the transmission mechanism 19 at the outer bottom of the water tank 13. The rotation of the motor 20 is transmitted to the pulsator 14 at the time of washing and to the washing and dewatering tub 15 at the time of dehydration via the driving pulley 21, the belt 23, and the driven pulley 22, respectively.

  An upper frame 24 is disposed on the upper portion of the main body 11, and a laundry input opening 25 for communicating the washing and dewatering tub 15 and the outside is formed in a substantially central portion of the upper frame 24, and the laundry The input opening 25 is covered with a lid 26 so as to be freely opened and closed. A control device 27 is arranged inside the front side of the upper frame 24, and a water supply valve 28 that can be opened and closed by electromagnetic force connected by a water tap (not shown) and a water supply hose 30 inside the rear frame. It is arranged.

  A drain valve 40 for stopping and draining the washing water in the aquarium 13 is provided at the bottom of the aquarium 13. When the drain valve 40 is opened during drainage, the washing water is drained to the outside through the drain hose 41.

  FIG. 2 shows a cross-sectional view of the main part around the silver ion elution device part of the washing machine in the embodiment of the present invention.

  In FIG. 2, the water supply valve 28 is provided on the rear part of the upper frame back plate 47 provided inside the upper frame 24, and the water flow path constituted by the upper frame back plate 47 and the water flow path cover 53. At the end of 54, a water supply box (water supply path) 36 is connected to the laundry input opening 25 side, and the water supply box 36 is provided inside the upper frame 24, and a screw 51 (see FIG. 4). Reference). In addition, a notch 56 is formed in the side wall of the laundry input opening 25, and the front side of the water supply box 36 is mounted so as to close the notch 56.

  The bag body storage portion 52 of the water supply box 36 contains a bag body 50 made of a nonwoven fabric that encloses a small piece of silver crystal material 4 kneaded with silver ions and allows water to pass through. An elution device 55 is configured.

  Then, the tap water supplied from the water supply hose 30 passes through the water passage 54 from the water supply valve 28 as indicated by the arrow, and the silver crystal in the bag body 50 accommodated in the water supply box 36 of the silver ion elution device 55. It contacts the surface of the material 4 and falls into the lower washing and dewatering tank 15 while dissolving the silver ions.

This silver crystal material 4 is formed as a large number of small pieces processed into a particulate solid state, with a material obtained by kneading silver ions in water-soluble diboron trioxide (B ₂ O ₃ ) as a main material. Yes.

  In the present embodiment, the components through which water is supplied from the water supply valve 28 to the water supply box (water supply path) 36 are collectively referred to as a water supply structure.

  FIG. 3 is a perspective view around the silver ion elution device portion of the washing machine in the embodiment of the invention, showing a view in which the screw 51 is not attached, and FIG. 4 is a water supply box portion of the silver ion elution device portion. An exploded perspective view is shown.

3 and 4, the water supply box 36 includes a box main body 36A and a box cover 36B, and stores a bag body 50 in which the silver crystal material 4 is enclosed in a bag body storage portion 52 in the box main body 36A. A silver ion elution device 55 is configured by covering the box cover 36B from above. The water supply box 36 is attached to the upper frame 24 from below. At this time, as described above, the notch 56 formed on the side wall of the laundry input opening 25 is provided on the front side of the water supply box 36. And is fixed to the upper frame body 24 with screws 51 from below.

  In addition, the box front surface 48 on the laundry input opening 25 side of the box body 36A is formed of a transparent material, and the cover front surface 49 on the laundry input opening 25 side of the box cover 36B is also transparent. When the lid body 26 is opened, the degree of consumption of the silver crystal material 4 in the bag body 50 accommodated in the water supply box 36 can be visually recognized. The front portion of the water supply box 36 facing the laundry input opening 25 includes at least one of the box front portion 48 and the cover front portion 49.

  About the washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The washing operation is started by a signal from the control device 27 and the water supply valve 28 is opened, so that tap water flows from the water supply hose 30 and flows into the water supply box (water supply path) 36. When this water comes into contact with the silver crystal material 4 in the bag body 50, Ag ions are melted and flow into the washing and dewatering tub 15. As a result, silver ions (Ag +) kneaded in the silver crystal material 4 are eluted in the water and adhere to the clothes, so that the laundry can be subjected to antibacterial treatment.

  The silver crystal material 4 needs to be replaced when the silver ions are consumed because the silver ions are consumed by passing water every time. Since the box front face 48 of the box main body 36A of the water supply box 36 and the cover front face 49 of the box cover 36B are formed of a transparent material, the degree of wear of the silver crystal material 4 in the bag body 50 is easy. It can be visually recognized. When it is consumed and needs to be replaced, it can be easily replaced by opening the lid body 26 and loosening the screw 51 from below the upper frame body 24 to remove the water supply box 36.

  In the present embodiment, the box front face 48 of the box main body 36A of the water supply box 36 and the cover front face 49 of the box cover 36B are formed of a transparent material. However, the box main body 36A and the box front The entire cover 36B may be formed of a transparent material.

  As described above, in the present embodiment, the silver ion elution device 55 uses a water supply non-woven bag body 50 having water permeability in which the small silver crystal material 4 kneaded with silver ions is enclosed. 36, and the laundry supply opening 25 side of the water supply box 36 is mounted so as to close the notch 56 formed on the side wall of the laundry input opening 25, and is screwed upward with a screw 51 from below. By adopting a configuration that is fixed to the frame body 24, the silver ion elution device 55 has an inexpensive structure, and can stably and efficiently perform elution of silver ions having antibacterial action on clothes over a long period of time. The silver crystal material 4 in the silver ion elution device 55 can be easily replaced.

  Further, the water supply box 36 is formed of a transparent material on the front surface facing the laundry input opening 25, and is composed of, for example, a box main body 36A and a box cover 36B, on the side of the laundry input opening 25 of the box main body 36A. A silver crystal material is formed by forming the box front face 48 and the cover front face 49 on the laundry input opening 25 side of the box cover 36B or the entire box body 36A and the box cover 36B from a transparent material. Since the amount of consumption of 4 can be easily visually recognized to determine the replacement time and can be replaced in a timely manner, the antibacterial action can be continued on the clothing.

  As described above, the washing machine according to the present invention is a silver ion eluting device having an inexpensive structure, can stably elute silver ions having an antibacterial action for a long period of time, and the consumption state of the internal silver crystal material Can be easily recognized, and the silver crystal material in the silver ion eluting device can be easily replaced, so that it can be applied to other washing machines such as a drum type washing machine.
