Definitions

  • the present disclosure mainly relates to a washing machine suitable for household use.
  • a so-called vertical washing machine has a drum which is open upwards for accommodating laundry and a tub for accommodating the drum (e.g., refer to a patent literature 1).
  • a water level of supplied water is generally set in a low position with a certain degree of allowance compared with a balancer arranged on an upper end of the drum in a washing process and a rinsing process of the washing machine.
  • a packing component is arranged between the tub and a tub cover to prevent the water from leaking outwards from the tub.
  • a purpose of the present disclosure is to provide a washing machine so as to effectively utilize a volume of a drum by preventing water in the drum from leaking from a tub.
  • the present disclosure adopts the following solution.
  • the washing machine of the present disclosure includes: a drum for accommodating laundry; a tub for accommodating the drum; a packing water-sealing part having a packing component arranged between an upper end part of the tub and an upper end part of the drum to inhibit water from leaking outwards from the tub; a labyrinth part adopting a labyrinth structure and for arranging ribs lower than the packing water-sealing part between a tub cover and the upper end part of the drum at an inner side of the packing water-sealing part; and a heightened drum arranged integrally with the tub cover for retaining water whose water level is higher than a water level at the upper end of the drum.
  • the heightened drum includes a lower end part configured to be continuous with the upper end part of the drum and a large-diameter upper end part formed with a diameter which gradually increases upwards from the lower end part.
  • the heightened drum is provided with an overflow hole in a side wall, and has an overflow hose for enabling the water to overflow outwards from the overflow hole.
  • a labyrinth part adopting a labyrinth structure and ribs lower than the packing water-sealing part are arranged between an tub cover and the upper end part of the drum at an inner side of the packing water-sealing part, so that clothes can be prevented from being entered into the labyrinth part even if a set water level is raised to enable the clothes to enter a clearance between the upper end part of the drum and the tub.
  • a highest water level in a washing process and/or a rinsing process is set to be higher than an upper end part of the drum, when the labyrinth part is in a state of air accumulation due to increase of a water level in the labyrinth part, and water is blocked and cannot enter due to the air accumulation.
  • the water in the drum can be prevented from flowing out of the tub side even if the water level is increased, thereby increasing water quantity for effectively implementing the washing process and the rinsing process.
  • the heightened drum is also arranged and the heightened drum is arranged integrally with the tub cover for retaining the water higher than a water level at the upper end of the drum. Therefore, the same effect as the washing machine with an increased volume of the drum can be obtained.
  • the heightened drum has a lower end part configured to be continuous with the upper end part of the drum and a large-diameter upper end part formed with a diameter which gradually increases upwards from the lower end part, the volume can be increased more effectively and throwing-in and taking-out of the drum of the laundry are performed easier.
