The invention provides a dehydration control method of a washing machine. The washing machine comprises a washing drum capable of being used for containing water in the washing process and a water collecting device for collecting water discharged from the washing drum, wherein a collected water level detecting device is arranged in the water collecting device. The control method comprises the following steps: in the dehydration process of the washing machine, if the water level detected by the collected water level detecting device reaches preset safe water level L0, dehydration is slowed downor suspended. According to the dehydration control method of the washing machine, the water level in a water collecting groove is detected by the collected water level detecting device, if the presetwater level is reached, dehydration water outlet speed needs to be reduced, the speed can be reduced to the preset speed by speed reduction, and the preset speed can be certain speed lower than the current speed or the speed is directly reduced to 0. Therefore, water splashing caused by excessive water in the water collecting groove is prevented with the dehydration control method of the washingmachine.

The invention provides a drainage device for a washing machine as well as the washing machine and a control method of the washing machine. The washing machine comprises an inner barrel and a water collection device, wherein a drain hole is arranged in the bottom of the inner barrel, no water exists between the inner barrel and the water collection device in a washing process, and water in the inner barrel enters the water collection device and is discharged from the water collection device during the washing process and a dehydration process; the drainage device comprises a sealing mechanism and a locking mechanism, wherein the sealing mechanism comprises a blocking component and a driving component; the blocking component is arranged in a drainage port to make the drainage hole normally closed; the driving component is provided with an output end which reciprocates in a direction parallel to a central axis of the inner barrel; the locking mechanism is used for locking and positioningthe inner barrel; the output end of the driving component reciprocates; and the blocking component is ejected to open the drain hole or reset to close the drain hole. According to the blocking component of the sealing mechanism of the drainage device, the self-sealing of the inner barrel can be realized, a function of double-power clothes washing is achieved, and after the inner barrel is locked through combination with a locking component, the sealing mechanism opens the drainage port more conveniently.

The invention provides a washing machine. The washing machine comprises a washing drum for containing water in the washing process and a water collecting device for collecting water discharged from the washing drum, wherein the water collecting device comprises a water collecting cavity and a water outlet communicated with the water collecting cavity, and a water guiding structure used for guidingwater to the water outlet is arranged at the bottom wall of the water collecting cavity. The washing drum of the washing machine is used as the water containing drum, an outer drum is no longer arranged outside the washing drum, only the water collecting device is arranged at the lower middle part of the washing drum, and washing water from the washing drum is discharged after being discharged tothe water collecting device. Therefore, the water collecting device is provided with the water collecting cavity to achieve the function of temporary storage of water. The water collecting device islower than the washing drum, the water guiding structure for guiding water flow to the water outlet is arranged on the bottom wall of the water collecting cavity, the water flow can be discharge timely, and overflow of the water collecting device due to excessive and rapid water accumulation is prevented.

The invention provides a washing machine. The washing machine comprises a washing drum used for containing water in a washing process and a water collecting device used for collecting water dischargedby the washing drum, wherein the water collecting device comprises a water collecting cavity, and a reinforcing structure used for increasing the strength of the water collecting cavity is arranged on a side wall of the water collecting cavity; the water collecting device is provided with a locking component, and the bottom of the washing drum is provided with a locking portion and an openable/closable water outlet of the washing drum; and the locking component acts to cooperate with the locking portion for locking the washing drum to open the water outlet of the washing drum. According to the washing machine, the washing drum is used as a water containing drum, an outer drum is not arranged outside the washing drum, only the water collecting device is arranged at the bottom of the washing drum, so that the washing water of the washing drum is discharged after being discharged to the water collecting device, when the washing drum drains water, the locking portion acts to cooperate with the locking portion of the washing drum to position and lock the washing drum, and meanwhile, the water outlet of the washing drum is opened to drain the water in the washing drum.

The invention provides a washing machine. The washing machine comprises a washing drum used for containing water in a washing process and a water collecting device used for collecting water dischargedby the washing drum, wherein the water collecting device comprises a water collecting cavity and at least one water outlet which communicates with the water collecting cavity; the water collecting device is provided with a locking component, and the bottom of the washing drum is provided with a locking portion and an openable/closable water outlet of the washing drum; the locking component acts to cooperate with the locking portion for locking the washing drum to open the water outlet of the washing drum. According to the washing machine, the washing drum is used as a water containing drum, an outer drum is not arranged outside the washing drum, the water collecting device is only arranged at the bottom of the washing drum, so that the washing water of the washing drum is discharged afterbeing discharged to the water collecting device, when the washing drum drains water, the locking component acts to cooperate with the locking portion of the washing drum to position and lock the washing drum, and meanwhile, the water outlet of the washing drum is opened to drain the water in the washing drum.

The invention discloses a washing machine filtering device and a washing machine. The washing machine comprises a cabinet and a washing drum rotatably arranged in the cabinet. The washing drum is configured as a barrel structure for holding water during washing. The filtering device is mounted on the inner peripheral wall of the washing drum, and comprises a mounting base and a filter. The mounting base is located on the inner peripheral wall of the washing drum, and is provided with a water guide channel and a filtering channel. The water guide channel is used for guiding water in the washing drum to be discharged out of the washing drum, and the filtering channel defines a water circulation path in the washing drum. The filter located on the mounting base is communicated with the filtering channel. The water guide channel and the filtering channel are arranged at an interval. The water is discharged out from a first drain outlet arranged on the lower portion of the peripheral wall of the washing drum through the water guide channel vertically arranged in the filtering device, so that the space for mounting a water channel can be saved, and the capacity expanding effect is improved.
