Drum washing machine and drum washing and drying machine

Abstract

The present invention relates to a drum type washing machine and a drum type washing and drying machine capable of discharging excess water to the outside when too much water is added to a tub. Wherein, the front side of the bucket (3) with the rotary drum (2) inside is covered by the bucket cover (3a), and the bucket cover (3a) is provided with a laundry inlet and outlet (11). The bucket cover (3a) is provided with an overflow port (57) upstream of the position of the drainage groove (10) in the direction of rotation of the rotary drum. The washing water added to the normal water level will not be discharged from the overflow port (57); and when adding too much water, the excess water will be discharged into the drainage channel (13) from the overflow port (57).

Description

technical field [0001] The present invention relates to a drum type washing machine which washes laundry loaded in the rotary drum by driving the rotary drum installed in the tub to rotate, and a drum type washing machine provided with a function of drying the laundry loaded in the rotary drum. Washer dryer. Background technique [0002] In the drum-type washing machine, the water tub is supported in the body of the washing machine through the suspension structure, and the water tub is provided with a rotating drum with many through holes on the wall. The laundry is loaded into the rotating drum, and the rotating drum is driven to rotate to perform various operations such as washing, rinsing, and dehydration. [0003] In the drum-type washing machine described above and the drum-type washer-dryer constructed by adding thousands of clothes functions to it, when the control of water inflow in the tub is abnormal, the amount of water inflow into the tub may be abnormal. incre...

Problems solved by technology

In order to prevent this phenomenon from happening, it is necessary to set up a valve body that blocks the above-mentioned opening, or to install components such as an anti-backflow valve and a drain valve in the overflow hose connected to the opening, thereby causing unnecessary increase in manufacturing cost. question

[0006] In addition, since the water overflowing from the opening part will flow to the bottom surface of the drum-type washer-dryer, when the drum-type washer-dryer is installed in a place without a drain pan or in a place with poor drainage, it may also occur. The problem of overflowing water and wetting the ground
