Example Six

This embodiment provides a method for controlling a washing machine, which specifically includes: during the washing process of the washing machine, the inner tub and the pulsator are in a relatively static state when rotating.

The washing machine in this embodiment is a washing machine with a pulsator, the inner tub is a washing tub, and the inner tub may be a perforated inner tub or a non-perforated inner tub. The pulsator is set at the bottom of the inner barrel. During the washing process of a general washing machine, the pulsator rotates to drive the water flow to wash the clothes. For a dual-power washing machine, the inner tub and pulsator can rotate during the washing process at the same time, and the water flow generated is stronger than when only the pulsator rotates. It is powerful, but only includes a relatively single washing water stream, the washing effect is limited, and the improvement is not significant.

This embodiment can realize that the inner tub and the pulsator are in a relatively static state during the washing process, thereby increasing the water flow pattern under the same direction and the same speed of the inner tub and the pulsator, increasing the variety of washing water flows, and realizing gentle washing. Improve the washing effect of clothes.

Specifically, the washing process of the washing machine includes a first operating state and/or a second operating state; in the first operating state, the inner tub and the pulsator are in relative motion when rotating, and in the second operating state, the inner tub and the pulsator The wheel is relatively stationary when rotating.

In the first operating state, the relative movement of the inner barrel and the pulsator includes: the inner barrel and the pulsator rotate in opposite directions with the same or different rotation speeds. In the second operating state, the inner barrel and the pulsator are in a relatively static state including: the inner barrel and the pulsator rotate in the same direction and at the same speed; specifically, the inner barrel and the pulsator rotate in a clockwise or counterclockwise direction at the same rotation speed.

In the same washing process, the washing machine can always keep the inner tub and the pulsator in a relatively static state when rotating; it can also keep in a relative motion state; it can also perform a relatively static state for only part of the time, and a relative motion for part of the time. It can be switched between to achieve a variety of water flows and further increase the washing effect.

As an implementation of this embodiment, this embodiment provides a washing machine control method, which specifically includes:

In the same washing process, the washing machine only executes the first operating state, or only executes the second operating state.

In this embodiment, during the same washing process, the inner tub and the pulsator can only perform the first operating state, the inner tub and the pulsator move relative to each other, and perform the same direction and different speed or reverse rotation movement, which can form a stronger water flow, which is beneficial to improve Washing effect.

In addition, during the same washing process, the inner tub and the pulsator can also only perform the second operating state. The inner tub and the pulsator always remain relatively static, that is to say, the inner tub and the pulsator rotate at the same speed and in the same direction during the washing process. The new form of water flow is conducive to gentle washing of soft-textured clothes.

The conditions of the inner tub and the pulsator rotating at the same speed and direction during the washing process include:

Case 1: The inner tub and the pulsator rotate in the same direction and speed in the clockwise direction during the washing process;

Situation 2: The inner tub and the pulsator have been rotating in the same direction and speed counterclockwise during the washing process;

Case 3: The inner tub and the pulsator are switched between rotating clockwise at the same speed and in the same direction and rotating counterclockwise at the same speed and in the same direction during the washing process.

In either case, during the same washing process, the inner tub and the pulsator have been kept relatively stationary, realizing the water flow form of the inner tub and the pulsator rotating in the same direction and at the same speed, which can be washed more gently and improve the quality of the soft clothes. Wash care effect.

The washing process of the washing machine includes a first operating state and a second operating state, and the first operating state and the second operating state can be switched;

Among them, in the first operating state, the inner barrel and the pulsator are in a relative motion state when rotating, and in the second operating state, the inner barrel and the pulsator are in a relatively static state when rotating.

In this solution, the two operating states can be switched during the washing process, and different washing water flows can be generated in the two operating states. This increases the variety of washing water flows, which can improve the washing efficiency and washing of clothes. ratio.

Specifically, the two operating states in the washing process include the relative static state of the inner tub and the pulsator and the relative motion state of the inner tub and the pulsator; the direction of water flow formed when the inner tub and the pulsator are in a relatively static state during rotation Consistent, the flow rate is stable, so that the pulling force or drafting force on the clothes is small, which can reduce the wear on the clothes and realize gentle washing; and when the inner tub and the pulsator move relative to each other, the strength of the water flow formed is greater. These states can be switched for washing and cooperate with each other to not only improve the washing effect, but also protect the clothes, reduce the wear and deformation of the clothes, and meet the needs of users.

During the washing process, in the second operating state, the inner tub and the pulsator are in a relatively static state, including: the inner tub and the pulsator rotate in the same direction and at the same speed. Among them, the inner barrel and the pulsator can rotate in a clockwise direction at the same rotation speed at the same time, and can also rotate in a counterclockwise direction. In this way, although both the inner tub and the pulsator are rotating, their movements are completely synchronized, and the two are relatively static. The water flow formed in the inner tub flows in the same direction at the same stable speed, and the clothes in the inner tub follow this way. The movement of the water stream has the least pulling force. For clothes that are easily deformed such as silk and wool, this gentle washing process is more suitable.

In the first operating state, the inner barrel and the pulsator can be in a relative motion state in a variety of ways. Different ways can form a relatively different and strong water flow. In this embodiment, the first operating state and the second operating state form The water flows cooperate with each other for washing. The movement mode of the inner tub and the pulsator in the first operating state can include the following schemes:

Scheme 1, the inner barrel and the pulsator rotate in opposite directions, and the rotation speed of the inner barrel and the pulsator are the same;

The inner bucket and the pulsator rotate in opposite directions. The rotation speed of the inner bucket and the pulsator are the same, forming two water streams that rotate in opposite directions. Where the two water streams meet, a stronger rotating water stream is formed, which will cause greater washing of the clothes and ensure Washing effect and cleanliness rate.

Scheme 2, the inner barrel and the pulsator rotate in opposite directions, and the rotation speed of the inner barrel and the pulsator are different. The effect is the same as that of the scheme 1. The rotation of the inner barrel and the pulsator can form a stronger rotating water flow, causing greater washing and washing of clothes. The pulling force ensures the washing effect and cleanliness rate.

As a preferred solution, when the inner tub and the pulsator rotate in reverse, the rotation speeds are different and the rotation speed difference is a fixed value or a variable value. In this way, a certain intensity of water flow can be preset, which is suitable for most clothes. It can not only ensure high washing efficiency, but also avoid damage to clothes.

Solution 3: In the first operating state, the inner tub and the pulsator rotate in the same direction, and the rotation speed of the inner tub and the pulsator are different. When the inner tub and the pulsator rotate in the same direction but at different speeds, a stronger rotating stream can be formed to ensure washing. effectiveness.

Further, the inner tub and the pulsator rotate at different speeds in the same direction, and the difference in rotation speed between the inner tub and the pulsator is a fixed value or a variable value; in this way, a certain intensity of water flow can be preset, which is also conducive to forming a stable washing program.

In the first operating state, the difference between the rotational speeds of the inner tub and the pulsator when the inner tub and the pulsator rotate in reverse is not greater than the difference between the rotational speeds when the inner tub and the pulsator rotate in the same direction and at different speeds. In this way, a relatively suitable strength and relatively stable water flow can be formed, and the washing effect and cleanliness rate can be improved.

In addition, in this embodiment, when the first operating state and the second operating state are switched during the same washing process, the specific method may include but not limited to the following specific solutions:

Solution 1: In the same washing process, the washing machine sequentially executes the first operating state/second operating state and the second operating state/first operating state.

In this solution, the washing machine executes the first operating state once and executes the second operating state once. The first operating state may be executed first and then the second operating state, or the second operating state may be executed before the first operating state. The operating time of the first operating state and the second operating state can be preset as needed. For example, after the user chooses to run the washing program, the washing machine first controls to execute the first operating state to reach T1 time, and then executes the second operating state to reach T2 time, where T1 time and T2 time can be the same or different, and can be preset according to needs. Set or set by the user.

Solution 2: The washing machine controls the first operating state and the second operating state to switch multiple times, and alternately executes the first operating state and the second operating state.

In this solution, the washing machine executes the first operation state and the second operation state n times, the first operation state and the second operation state alternately operate, and the washing machine switches between the two regularly or irregularly. In this way, the water flow formed in the washing process is more diversified, and the two operating states cooperate with each other to achieve the purpose of high washing efficiency and high cleanliness rate of clothes, and also greatly reduce the wear on clothes.

A further solution is to alternately execute the first operating state and the second operating state during the same washing process, and each time in the first operating state, the pulsator and the inner tub rotate in reverse or both the pulsator and the inner tub rotate in the same direction and at different speeds , In the second operating state, the inner barrel and the pulsator rotate in the same direction and speed in the clockwise or counterclockwise direction.

When the washing machine alternately executes the first operating state and the second operating state for multiple times, in the first operating state, the operating state of the inner tub and the pulsator may be the same or different each time, for example, the inner tub and the pulsator are reversed each time Rotate in the same direction, or move at different speeds in the same direction each time, so that the operation is more regular and the rotation direction of the clothes is also more regular, which can reduce the entanglement of the clothes. Or, the inner tub and the pulsator rotate in the opposite direction at the previous time, and the inner tub and the pulsator rotate in the same direction at different speeds in the next time, so that a more diversified water flow can be formed and the cleaning rate of clothes can be improved. In the second operating state, the inner barrel and the pulsator rotate in the same direction and the same speed. Each time the second operating state is switched, the inner barrel and the pulsator can rotate at the same or different speed as the previous one, and can rotate in a clockwise direction. It can also be rotated counterclockwise.

In a further solution, in the same washing process, the washing machine alternately executes the first operating state and the second operating state, and each time in the first operating state, the pulsator and the inner tub rotate in reverse each time, and the pulsator and the inner tub The speed difference is a fixed value. Each time in the second operating state, the pulsator and the inner barrel rotate in the clockwise direction in the same direction and speed each time. In this way, the operation of the inner tub and the pulsator is more regular, and the rotation direction of the clothes is also more regular, which can reduce the entanglement of the clothes.

In a further solution, in the second operating state, the pulsator and the inner tub rotate in the same direction, and the rotational speed is both V1, and the V1 is not less than the smaller value of the rotational speed when the inner barrel and the pulsator rotate in the first operating state. In this way, the washing efficiency and washing ratio of the clothes can be improved, and the abrasion on the clothes can be reduced, and gentle washing can be realized, so as to meet the needs of users.

As an implementation of this embodiment, this embodiment provides a washing machine control method. In this embodiment, the washing process runs in the first state, or runs in the second operating state, or runs in the first and second operating states. . In the first operating state, the inner barrel and the pulsator are in a relative motion state when rotating, and in the second operating state, the inner barrel and the pulsator are in a relatively static state when rotating.

In this embodiment, the second operating state may be added to the washing process of the ordinary washing program of the existing washing machine, or the soft washing mode may be separately set on the existing washing machine, the soft washing mode may be added, and the soft washing process may be performed separately. When the user selects the normal washing program or the gentle washing mode that can be switched during the washing process, the washing machine switches between the first operating state and the second operating state during the washing process, or executes the second operating state alone.

Specifically, in this embodiment, on the basis of the existing washing machine program, the gentle washing program can be set separately, adding washing programs selectable by the user, enriching the washing machine program, and enhancing the user experience, including:

In order to facilitate the user's choice, the existing washing machines include ordinary washing programs, quick washing programs, etc. The washing machines also include soft washing programs and powerful washing programs. During the washing process of the soft washing program, the washing machine can only perform the second operating state, or Switch between the first operating state and the second operating state; during the washing process of the powerful washing program, the washing machine executes the first operating state. During the operation, the inner tub and the pulsator rotate in reverse to form a stronger water flow and improve the washing effect .

The soft washing program is an additional program on the basis of the existing washing machine. For soft clothes, when the user selects the soft washing program and runs, the washing machine can only perform the second operating state alone, and the inner tub and the pulsator can be at the same speed The same direction rotates in a clockwise and/or counterclockwise direction, and when the user selects a strong washing program next time, it switches to the first operating state to perform the washing process. The gentle washing program can also be switched between the first operating state and the second operating state, so that the stronger water flow and the softer water flow can be switched to run, so as to achieve the purpose of enriching the washing water flow, improving the washing effect, and avoiding clothing deformation.

In this way, the washing machine's programs include not only ordinary washing programs, but also powerful washing programs and gentle washing programs. Users can independently select appropriate washing programs according to the texture of the clothes and the degree of soiling, and can be between different washing programs/operating states. Switching, not only enriches the washing program of the washing machine, enriches the washing water flow, and enhances the user experience, but also achieves the purpose of improving the effect of washing and protecting clothes.
