Problems solved by technology

However, during dehydration and drainage, the applicant found that if the drain valve or the drain pump fails or the user forgets to put down the drain pipe when washing, the water cannot be drained at this time, which will cause water to overflow from the water collection structure and flow to the ground or the electrical components at the bottom of the washing machine , not only will cause the failure of the washing machine, but also cause adverse effects on the user's home floor

Embodiment 1

[0044]This embodiment provides a drainage control method for a washing machine. The inner tub of the washing machine is provided with a water collection structure for collecting the water discharged from the inner tub. The drainage process of the washing machine includes a pre-drainage process and a main drainage process. The washing machine performs pre-drainage first when draining. In the process of pre-drainage, it is judged whether there is drainage abnormality by detecting the change of water level in the water collection structure within a period of time.

[0045] By providing the water collecting structure, the water drained from the inner tub 200 can be discharged through the water collecting structure during dehydration and draining. During washing and rinsing, the inner bucket 200 is a water-filled bucket, which realizes that there is no outer bucket outside the inner bucket 200, the movable space of the inner bucket 200 is increased, and the possibility of collision ...

Embodiment 2

[0062] Such as figure 1 As shown, this embodiment provides a washing machine with the drainage control method as described in Embodiment 1. The washing machine includes a cabinet 100, an inner tub 200 disposed in the cabinet 100 and a driving device for driving the inner tub 200 to rotate. 300, the inner tub 200 is a water-holding bucket during laundry, and a water collecting structure is arranged on the outside of the inner tub 200. During dehydration and drainage, the water discharged from the inner tub 200 is discharged through the water collecting structure; it also includes a water level detection device, the water level detection device connected to the catchment structure.

[0063] By providing the water collecting structure, the water drained from the inner tub 200 can be discharged through the water collecting structure during dehydration and draining. During washing and rinsing, the inner bucket 200 is a water-filled bucket, which realizes that there is no outer buc...

Embodiment 3

[0077] Such as figure 1 As shown, this embodiment is a further limitation of Embodiment 2. In this embodiment, the water collection structure includes a mounting plate 500 and a water retaining rib 501 arranged on the mounting plate 500. The mounting plate 500 and the water retaining rib 501 The water collecting cavity 400 is enclosed and formed, and the air chamber 802 is arranged on the mounting plate 500 and located outside the water retaining rib 501 .

[0078] The mounting plate 500 is a horizontal plate, and the water retaining rib 501 is arranged on the mounting plate 500 , and is fixed and sealed with the mounting plate 500 or integrally formed. The mounting plate 500 and the water retaining rib 501 are surrounded to form the water collecting chamber 400, the mounting plate 500 forms the bottom wall of the water collecting chamber 400, and the water retaining rib 501 forms the side wall of the water collecting chamber 400, so the structure is simple and convenient Pro...

Abstract

The invention belongs to the field of washing machines, and discloses a washing machine drainage control method and a washing machine. The inner tub of the washing machine is provided with a water collection structure for collecting water discharged from the inner tub. The washing machine's drainage process includes a pre-drainage process and a main drainage process. During the pre-drainage process, the water level change in the water collection structure within a period of time is detected to determine whether there is drainage abnormality. The washing machine of the present application is equipped with a water collection structure outside the inner tub, which can not only collect the water discharged from the inner tub, but also reduce the space occupied between the inner tub and the washing machine body, and achieve a good capacity expansion effect; In the drainage process, by detecting the water level change in the water collection structure, the abnormal drainage of the washing machine can be found in time, so as to prevent the water from overflowing from the water collection structure to the electrical components or the ground inside the washing machine, and avoid causing losses to the user.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a washing machine drainage control method and the 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 ...
