Conventionally, a so-called vertical-type washing machine is known, which includes an inner tub opened upward for accommodating laundry, and an outer tub accommodating the inner tub (for example, see Patent Document 1). In order to prevent the water from overflowing to the outer side of the outer tub, the water level of the water supplied during the washing process and the rinsing process of the washing machine is generally set to have a certain margin compared to the balancer provided at the upper end of the inner tub. low position. Furthermore, there is also a method in which a seal is provided between the outer tub and the outer tub cover to prevent water from leaking out from the outer tub for water that has passed the balancer of the inner tub and reaches the inner surface of the tub body of the outer tub.

However, not only the above-mentioned patent documents, but also in such a conventional vertical washing machine, the washing process and the rinsing process in which water is stored to the water level near the upper end cannot be pursued so as to more effectively utilize the volume of the inner tub. Assuming that if the set water level is raised to increase the amount of water that goes around the side of the tub, the water sealing measure will become a problem if the screw fixing position for tightening the seal provided between the tub and the tub cover is not increased. Did not do well.

Furthermore, when there is a demand to raise the water level to a position higher than the upper end of a balancer or the like provided with the inner tub, the current situation is a conventional method for preventing water from leaking between the seal, the water seal and the outer tub. The water seal structure of the seal cannot cope with it.
