Example Embodiment

[0044] Embodiment one

[0045] like figure 1 As shown, the washing machine of this embodiment includes a washing tub that can be used to hold water during the washing process and a water collecting device for collecting the water discharged from the washing tub. Bucket, in this embodiment, only a water collecting device is provided at the bottom of the washing bucket. During the dehydration process, the water that escapes is discharged into the water collecting device. If there is too much water in the water collecting device, the high-speed dehydration of the washing bucket will cause water splashing.

[0046] Therefore, the water collection device described in this embodiment is provided with a water collection level detection device, and the washing machine dehydration control method of this embodiment includes: during the dehydration process of the washing machine, if the water level detected by the water collection level detection device reaches the preset safe water le...

Example Embodiment

[0056] As an implementation manner of this embodiment, the suspension of dehydration includes:

[0057] The washing machine presets the minimum dehydration water level Lmin of the water collection device (Lmin is a set value). During the suspension of the dehydration process, when the water level detected by the water collection level detection device reaches the minimum drainage water level, the dehydration is restarted.

[0058] Further, the washing machine presets a maximum suspended dehydration time, and when the suspended dehydration time reaches the maximum suspended dehydration time, the dehydration is stopped and an alarm is given.

[0059] As another implementation manner of this embodiment, the suspension of dehydration includes:

[0060] The washing machine is set to suspend the dehydration time interval T0. When the dehydration suspension time reaches the suspension dehydration time interval T0, it is judged whether the water level in the water collecting device is...

Example Embodiment

[0064] Embodiment two

[0065] like figure 2 As shown, a washing machine includes a water level detection device, a washing tub 200 that can be used to hold water during the washing process, and a water collection device 500 for collecting the water discharged from the washing tub. The water level detection device includes a washing tub 200 for detecting The washing water level detection device 1002 for the inner water level and the water collection level detection device 1001 for detecting the water level in the water collection device 500 .

[0066] The washing tub 200 of the washing machine in this embodiment is used as a water bucket, and the outer tub is no longer provided outside the washing tub 200. In this embodiment, only a water collecting device 500 is provided at the bottom of the washing tub 200. The water level detection device of this embodiment includes a water level detection device for detecting washing The washing water level detection device 1002 of the...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of laundry equipment, in particular to a method for controlling dehydration of a washing machine. Background technique [0002] A washing machine is designed as a device for washing clothes by using electricity. In general, a washing machine includes: a tub for containing washing water; a rotary tub rotatably installed inside the tub; a pulsator rotatably installed in the rotary tub The bottom; motor and clutch, are configured to rotate the rotating barrel and pulsator. When the rotary tub and the pulsator rotate in a state that laundry and detergent are introduced into the rotary tub, the pulsator agitates wash water together with the laundry introduced into the rotary tub, thereby removing stains from the laundry. [0003] In order to increase the washing capacity of the washing machine, a larger rotary tub is required, that is, the height or diameter of the rotary tub needs to be increased. If the rotar...
