Problems solved by technology

[0004] However, in order to solve the problem that the washing water is filled between the inner tub and the outer tub and cause dirt and dirt between the inner tub and the outer tub, a washing machine with a non-porous inner tub has been proposed.
The non-porous inner tub independently holds laundry water during the washing process, and there is no water between the inner tub and the outer tub. However, the judgment logic involved in the above patent requires that the turbidity sensor needs to be in contact with the laundry water at all times. application inconvenience
On the other hand, the start time of the turbidity judgment in the above-mentioned patent is limited by the preset time of washing, and cannot fully exert the function of the washing machine to stop immediately after washing.
Moreover, the inner tub in the non-porous inner tub washing machine can be in a rotating state during the washing process, which poses new challenges for water quality detection

Embodiment 1

[0055] During the washing process of the washing machine involved in the present invention, the inner tub rotates, and the water quality detection device 32 is used to detect the water quality in the inner tub. The specific structure of the washing machine can be as follows: figure 1 The shown dual-power washing machine can also be a conventional non-porous inner tub washing machine.

[0056] like figure 1 Shown is a dual-power washing machine, the deceleration clutch device 5 has two power output ends, the pulsator 3 and the bottom of the bucket 4 are respectively connected to one of the power output ends, driven by the drive motor 6, the pulsator 3 and the inner bucket rotate simultaneously . During the washing and rinsing process, the pulsator 3 and the inner tub rotate in opposite directions, which can effectively increase the diversity of water flow, enhance the disturbance to the clothes, and improve the washing effect; during dehydration, the pulsator 3 and the inner t...

Embodiment 2

[0089] In order to improve the drainage capacity of the non-porous inner bucket, in embodiment one as figure 1 dual power washing machine as shown, or as figure 2 Shown washing machine is provided with drainage device, and present embodiment uses figure 2 The structure of the washing machine in is introduced to the drainage device.

[0090] like Figure 4 As shown, in this embodiment, in order to realize the drainage of the non-porous inner barrel, a plurality of drain outlets 14 are arranged at the lowest position on the barrel bottom 4 , and the plurality of drain outlets 14 are all distributed inside the same circular ring 13 .

[0091] In the present embodiment, a plurality of drain outlets 14 are designed at the bottom of the barrel 4, and the drain outlets 14 can be designed to be very small, so as to have a certain lint filtering effect during drainage and avoid lint clogging. The plurality of water outlets 14 are all distributed inside the same ring 13 , which is ...

Embodiment 3

[0123] This embodiment involves a water quality detection device 32 on the basis of the above embodiments. The water quality detection device 32 is arranged on a drainage sealing device (not shown in the figure), specifically on the sealing mechanism or the drainage mechanism. This setting can ensure that the water quality detection device is always in contact with the laundry water during the laundry process, ensuring the accuracy and reliability of the measurement by the water quality detection device 32 , and there is no delay in the detection process, saving time. When drainage is required, the drainage will flow out from the first drainage hole 105 and directly flush on the water quality detection device 32, which can play a good flushing effect on the water quality detection device 32 and avoid the detection accuracy being affected by the accumulation of dirt in the washing process. As a result, the detection accuracy of the water quality detection device 32 is ensured, a...

Abstract

The invention discloses a washing machine that comprises an inner barrel, wherein the inner barrel rotates during clothes washing and independently contains washing water; and the washing machine alsocomprises a water quality detection device used for detecting water quality information of the washing water in the inner barrel. The invention further discloses a control method of the washing machine; the washing machine comprises a control system electrically connected with the water quality detection device, and the control system controls a washing process according to the water quality parameter measurement value fed back by the water quality detection device. The water quality detection device is adopted for detecting the water quality in the non-porous inner barrel, the washing machine is controlled to stop immediately after being cleaned, the effects of saving water and electricity can be achieved, meanwhile, control over a washing state is enhanced, and the situation that clothes are damaged by clothes treating agent residues due to incomplete washing or incomplete rinsing is avoided.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine and a control method thereof. Background technique [0002] As an important household appliance in household life, the washing machine has greatly improved the quality of life of residents. With the improvement of people's living standards, the requirements for the intelligent level of washing machines are getting higher and higher. Existing washing machines generally use a timed washing mode, but the timed washing mode is not conducive to the control of the cleanliness of the clothes. Usually, there are problems such as long washing time, waste of power and water resources, and short washing time causing the cleanliness of the clothes to not meet the standard. . [0003] The Chinese patent with the application number 200710084288.5 discloses a method of instant-stop washing clothes and a washing-stop automatic washing machine applying the...
