Description

  The present invention relates to a washing machine including a net for sterilizing and deodorizing clothes and small items, and having a net attaching portion in a washing and dewatering tub.

  Conventionally, this type of washing machine has a dedicated net for processing laundry without directly contacting the pulsator with the laundry, in addition to stirring and washing the laundry with a pulsator for stirring in the washing and dewatering tank. The structure to mount is proposed (for example, refer patent document 1).

  FIG. 6 is a vertical cross-sectional view of a conventional washing machine, and FIG. 7 is a cross-sectional view of a main part of the washing machine.

  6 and 7, a net 112 is a ring 114 having a rectangular cross section with a long side in a longitudinal direction on a substantially quadrangular planar net body 113 having four corners aligned with the curved surface of the side wall of the washing / dehydrating tub 101. The ring 114 uses a spring material having elasticity, and the net 112 keeps its shape by the spring force of the ring 114. The corner portion of the net 112 rides on a step portion 115 on the inner wall of the washing / dehydrating tub 101, is attached so as to cover the pulsator 102, and is pressed by the clothing 116 on the net 112. The straight portion of the net 112 serves as a relief for the circulating water channel 109 in the washing and dewatering tank 101.

  With the above configuration, the clothes 116 are placed on the net 112 at the time of washing, and the clothes 116 and the pulsator 102 do not directly contact each other. As the pulsator 102 rotates, a water flow 117 as shown by an arrow is generated, and the clothes 116 are washed by the force of this water flow and the water discharged from above the circulating water channel 109 by the pump action of the pulsator 102. This washing method prevents the garment from being damaged and damaged. If the washing machine has a drying function in addition to washing delicate clothes, the net 112 can discharge hot air from above to dry clothes such as small items on the net 112, and charged fine particle water. If it has the generation | occurrence | production function, it can also disinfect and deodorize clothes, such as a small article on the net | network 112, by spraying charged fine particle water from upper direction.
