Description
Technical Field
The invention belongs to the technical field of washing machines, and particularly relates to a washing machine and a control method thereof.
Background
With the continuous progress of science and technology, the hands of people are gradually liberated from heavy physical labor, and particularly, at the present day that the life pace is gradually accelerated, people are used to clean clothes by a machine washing mode instead of a hand washing mode. Meanwhile, as more and more kinds of washing machines appear in the market, people begin to put forward higher and higher requirements on the comprehensive performance of the washing machines. In particular, in the process of washing the clothes, lint generated by the clothes is accumulated in the washing machine, and in order to prevent the existence of the lint from affecting the washing quality of the washing machine, the existing washing machines are provided with a lint collecting device to collect the lint, so as to effectively ensure the washing quality of the washing machine; however, most of the existing washing machines only have the function of collecting lint, but do not have the function of self-cleaning the lint filtering device, and the cleaning effect of some washing machines with the self-cleaning function is not very ideal.
Accordingly, there is a need in the art for a new washing machine and a control method thereof to solve the above-mentioned problems.
Disclosure of Invention
In order to solve the above problems in the prior art, that is, to solve the problem that the cleaning effect of the conventional washing machine on the lint collecting device is not good, the present invention provides a control method for a washing machine, in which a lint filtering member is provided at the bottom of an inner tub of the washing machine, and a water level in the washing machine is obtained during a first draining operation of the washing machine; when the water level in the washing machine is less than or equal to a predetermined water level, the inner tub of the washing machine is rotated to remove lint attached to the lint filtering member by rinsing.
In the above-described preferred embodiment of the control method for a washing machine, before the step of "rotating an inner tub of the washing machine", the control method further includes: stopping the washing machine from performing the first draining operation.
In a preferred aspect of the above control method for a washing machine, after the step of "rotating an inner tub of the washing machine", the control method further includes: causing the washing machine to perform a second draining operation.
In a preferred embodiment of the above control method for a washing machine, the step of "rotating an inner tub of the washing machine" includes: rotating an inner tub of the washing machine at a first predetermined rotational speed.
In the above preferred embodiment of the control method for a washing machine, the step of "rotating an inner tub of the washing machine at a first predetermined rotation speed" includes: and rotating the inner tub of the washing machine at the first preset rotating speed for a preset time.
In a preferable aspect of the control method for a washing machine described above, the control method further includes, during the first draining operation of the washing machine: rotating the inner tub of the washing machine at a second predetermined rotational speed.
In a preferable embodiment of the control method for a washing machine described above, the first predetermined rotational speed is less than the second predetermined rotational speed.
In a preferred aspect of the control method for a washing machine described above, the first drain operation and the second drain operation are drain operations in a washing mode of the washing machine and/or a rinsing mode of the washing machine.
In a preferred technical solution of the above control method for a washing machine, the washing machine is a pulsator washing machine, and the predetermined water level is a water level flush with a top of a pulsator of the washing machine.
The invention also provides a washing machine comprising a controller capable of executing the control method in any one of the above preferred technical solutions.
As can be understood by those skilled in the art, in the technical solution of the present invention, the lint filtering member is provided at the bottom of the inner tub of the washing machine, and the control method of the present invention includes: acquiring a water level in the washing machine in the process of executing a first water draining operation by the washing machine; when the water level in the washing machine is less than or equal to a predetermined water level, the inner tub of the washing machine is rotated to remove lint attached to the lint filtering member by rinsing. The control method of the invention realizes the cleaning of the thread scrap filtering component by rotating the inner barrel of the washing machine, and the thread scrap attached to the thread scrap filtering component can move along with the water flow in the rotating process of the inner barrel, thereby effectively avoiding the problem that the thread scrap is easy to attach to the thread scrap filtering component and can not be cleaned. Meanwhile, the control method of the invention also collects the water level in the washing machine as a basic parameter, so that the control method can judge the time of the rotation of the inner barrel according to the water level information. It can be understood that, when the amount of water in the washing machine is excessive, although the operation of rotating the inner tub can remove lint from the lint filter member, the lint is attached to the lint filter member again in a later draining process, i.e., the effect of removing the lint cannot be less than or equal to that; when the water amount in the washing machine is too small, the inner barrel is rotated to take away all the thread scraps, namely, when the water amount in the washing machine is too small, the inner barrel is rotated to difficultly flush the thread scraps filtering component; therefore, the present invention effectively removes lint attached to the lint filter member by rotating the inner tub of the washing machine at a predetermined water level, thereby effectively ensuring the cleaning effect of the washing machine on the lint filter member and thus effectively ensuring the washing quality of the washing machine. Preferably, the predetermined water level is a water level flush with a top of a pulsator of the washing machine.
Further, the control method of the present invention stops the washing machine from performing the first draining operation before rotating the inner tub, so that the water in the washing machine can better flush the lint filtering element during the shaking process, thereby effectively preventing the first draining operation from affecting the flushing process.
Further, the control method of the present invention effectively avoids the problem that the lint mixed in the water is re-attached to the lint filter member by causing the washing machine to perform the second draining operation after the lint filter member is flushed by the operation of rotating the inner tub, so that the lint mixed in the water can be timely drained.
Further, the control method of the present invention effectively cleans the lint filtering member by rotating the inner tub at the first predetermined rotation speed; it is understood that the first predetermined rotation speed is preferably a dehydration rotation speed of the washing machine, and a higher rotation speed not only can spin-dry the laundry in the inner tub but also can drive all lint on the lint filtering member to follow the movement, thereby effectively preventing the problem of lint reattachment. Meanwhile, the washing machine needs to control the inner tub to rotate at the first predetermined rotational speed for a predetermined time in order to effectively ensure that all lint has been separated from the lint filtering member. In addition, during the first draining operation of the washing machine, the inner tub is rotated at a second predetermined small rotation speed to prevent lint in water from adhering to the tub wall of the inner tub.
Further, as a preferred embodiment, the first and second draining operations are draining operations in a washing mode of the washing machine and/or a rinsing mode of the washing machine, that is, the washing machine may clean the lint filtering member while performing the washing mode and/or the rinsing mode without a separate mode for washing the lint filtering member, so that time and energy can be maximally saved for a user while ensuring a washing quality of the washing machine.

Furthermore, in the description of the present invention, unless explicitly stated or limited otherwise, the terms "connected" and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring first to fig. 1, there is shown an internal structure of a washing machine according to the present invention. As shown in fig. 1, the washing machine of the present invention includes an outer tub (not shown) and an inner tub 11 disposed in the outer tub, wherein a lint filter member 12 is disposed at the bottom of the inner tub 11. Preferably, the lint filter member 12 has an outer diameter greater than that of a drain center hole at the bottom of the inner tub 11, so as to ensure that water flowing out of the drain center hole can flow through the lint filter member 12. In the present preferred embodiment, the lint filtering member 12 is provided in an umbrella structure having a high middle and a low edge, so that a gap can be formed between the edge of the lint filtering member 12 and the bottom of the inner tub 11, through which lint in the inner tub 11 can be discharged from the inner tub 11.

Further, the washing machine is provided with a washing mode and a rinsing mode, the washing mode including a water supply operation, a washing operation, and a water discharge operation; when the washing machine performs a washing operation, as the pulsator of the washing machine is continuously rotated, washing water in the washing machine moves to one side close to the wall of the inner tub 11 by a centrifugal force so that a low pressure region is formed at a position close to the pulsator, and at this time, the washing water in the washing machine flows to below the lint filtering member 12 through a gap between the inner tub 11 and the outer tub and flows back into the inner tub 11 through the central hole of the drain of the inner tub 11 through the lint filtering member 12; it can be understood that, when the washing water flows through the lint filtering member 12, lint in the washing water adheres to the lint filtering member 12 and does not flow into the inner tub 11, thereby filtering the washing water. It should be noted that the description of this process is only exemplary, and the present invention does not impose any limitation on the process of filtering lint for the washing machine.
Still further, the washing machine includes a controller capable of controlling an operation program of the washing machine; meanwhile, it should be noted that the present invention does not limit the specific structure and model of the controller, and the controller may be an original controller of the washing machine, or a controller separately provided for executing the control method of the present invention. In addition, the washing machine further includes a water level detection member capable of detecting a water level within the washing machine, and the controller is capable of acquiring water level information detected by the water level detection member, so that the controller can control an operation program of the washing machine according to the water level information of the washing machine. It can be understood by those skilled in the art that the present invention does not impose any limitation on the specific structure of the water level detection member as long as the water level detection member can detect the water level in the washing machine and the controller can acquire the water level information of the washing machine through the water level detection member.
Referring next to fig. 2, a flow chart of the main steps of the control method of the present invention is shown. Based on the washing machine described in the above embodiment, the control method of the present invention mainly includes the following steps:
