Example four

The embodiment provides a control method of a washing machine, which specifically comprises the following steps: the washing process of the washing machine comprises that the inner barrel and the impeller are in a relatively static state when rotating.

The washing machine in the embodiment is a washing machine with a wave wheel, the inner barrel is a washing barrel, and the inner barrel can be a perforated inner barrel or a non-perforated inner barrel. The impeller is arranged at the bottom of the inner barrel. In the washing process of a general washing machine, the impeller rotates to drive water flow to operate, clothes are washed and cleaned, for the double-power washing machine, the inner barrel and the impeller can rotate in the washing process at the same time, the generated water flow is stronger than that generated when only the impeller rotates, but only single washing water flow is included, the washing effect is limited, and the improvement is not obvious.

This embodiment can realize that interior bucket and impeller are in relative static state when rotatory at the washing in-process to increase the rivers form under interior bucket and the equidirectional same-speed rotation of impeller, increased the variety of washing rivers, realize gentle washing, improve the washing of clothing and protect the effect.

Specifically, the washing process of the washing machine comprises a first operation state and/or a second operation state; in the first running state, the inner tub and the pulsator are in a relative motion state while rotating, and in the second running state, the inner tub and the pulsator are in a relative rest state while rotating.

In a first operation state, the relative motion state of the inner barrel and the impeller comprises the following steps: the inner barrel and the impeller rotate reversely at the same or different rotating speeds. Under the second running state, the inner barrel and the impeller are in a relative static state and comprise: the inner barrel and the impeller rotate in the same direction and at the same speed; specifically, the inner tub and the pulsator rotate simultaneously in a clockwise direction or a counterclockwise direction at the same rotational speed.

In the same washing process, the washing machine can keep the inner barrel and the impeller in a relatively static state when rotating all the time; the relative motion state can be kept all the time; the washing machine can also execute a relative static state in part of time and move in part of time, and different states can be switched, so that various water flows are realized, and the washing effect is further improved.

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

in the same washing process, the washing machine performs only the first operation state, or performs only the second operation state.

In this embodiment, in the same washing process, the inner tub and the pulsator may only perform the first operation state, and the inner tub and the pulsator may move relatively to perform the equidirectional and different-speed or reverse-direction rotation motion, so that a stronger water current may be formed, which is advantageous to improve the washing effect.

In addition, in the same washing process, when the inner tub and the pulsator can only execute the second running state, the inner tub and the pulsator can be kept in a relatively static state all the time, namely, the inner tub and the pulsator rotate in the same speed and the same direction in the washing process to form a new type of water flow, which is beneficial to soft washing of soft clothes.

The conditions that the inner barrel and the impeller rotate at the same speed and the same direction in the washing process comprise that:

case 1: the inner barrel and the impeller rotate at the same speed in the same direction in the clockwise direction in the washing process;

case 2: the inner barrel and the impeller rotate at the same speed in the same direction and the same direction in the counterclockwise direction all the time in the washing process;

case 3: the inner tub and the pulsator are switched between clockwise rotation at the same speed and counterclockwise rotation at the same speed in the washing process.

No matter which kind of circumstances, in same washing process, interior bucket and impeller are in the state that keeps relative static always, have realized the rivers form under interior bucket and the equidirectional same-speed rotation of impeller, can wash gentleness more, improve the washing and protecting the effect to gentle texture clothing.

the washing process of the washing machine comprises a first operation state and a second operation state, and the first operation state and the second operation state can be switched;

in the first running state, the inner tub and the impeller are in relative motion state while rotating, and in the second running state, the inner tub and the impeller are in relative rest state while rotating.

In this scheme, can switch between two kinds of running state in the washing process, can produce different washing rivers under two kinds of running state, so increase the variety of washing rivers, can improve the washing efficiency and the clean ratio to the clothing.

Specifically, the two operation states in the washing process comprise a state that the inner barrel and the impeller are relatively static and a state that the inner barrel and the impeller are relatively moved; when the inner barrel and the impeller are in a relative static state in the rotating process, the formed water flow direction is consistent, the flow speed is stable, and thus the pulling force or the stretching force applied to clothes is small, the abrasion to the clothes can be reduced, and the soft washing can be realized; and under the state of interior bucket and impeller relative motion, the rivers intensity of formation is great, so, the washing is switched to these two kinds of states, mutually supports, can enough improve the washing effect, can also reach the protection clothing, reduces the effect of clothing wearing and tearing deformation, satisfies user's demand.

In the washing process, in the second running state, the relative static state of the inner barrel and the impeller comprises the following steps: the inner barrel and the impeller rotate in the same direction and at the same speed. Wherein, the inner barrel and the impeller can rotate clockwise or anticlockwise at the same speed. Therefore, although the inner barrel and the impeller rotate, the movement of the inner barrel and the impeller is completely synchronous, the inner barrel and the impeller are relatively static, the water flow formed in the inner barrel flows towards the same direction at the same stable speed, the clothes in the inner barrel move along with the water flow, the pulling force is minimum, and the soft washing process is more suitable for the clothes which are easily deformed, such as silk and wool.

And under first running state, the mode that interior bucket and impeller are in relative motion state can include the multiple, and the rivers that intensity is big that comparatively different modes can form comparatively, and rivers that first running state and second running state formed in this embodiment are mutually supported and are washed, and the motion mode of interior bucket and impeller can include following several kinds of schemes under the first running state:

in the scheme 1, the inner barrel and the impeller rotate reversely, and the rotating speeds of the inner barrel and the impeller are the same;

the inner barrel and the impeller rotate reversely, the rotating speeds of the inner barrel and the impeller are the same, two water flows rotating in opposite directions are formed, strong rotating water flows are formed at the meeting positions of the two water flows, the clothes are greatly washed, and the washing effect and the cleaning rate are guaranteed.

Scheme 2, interior bucket and impeller carry out the counter rotation, and the rotational speed of bucket and impeller is different simultaneously, and is the same with scheme 1 effect, and the rotation of interior bucket and impeller can form stronger rotatory rivers, causes great washing away and pulling force to the clothing, guarantees washing effect and clean rate.

As a preferred scheme, when the inner tub and the pulsator rotate in opposite directions, the rotation speeds are different and the difference value of the rotation speeds is a fixed value or a variable value, so that water flow with certain strength can be preset, the strength of the water flow is suitable for most clothes, high washing efficiency can be guaranteed, and the clothes can be prevented from being damaged.

In the scheme 3, in the first running state, the inner barrel and the impeller rotate in the same direction, the rotating speeds of the inner barrel and the impeller are different, and when the inner barrel and the impeller rotate in the same direction but at different speeds, rotating running water with high strength can be formed, so that the washing efficiency is guaranteed.

Further, the inner barrel and the impeller rotate in the same direction and at different speeds, and the difference value of the rotating speeds of the inner barrel and the impeller is a fixed value or a variable value; therefore, the water flow with certain strength can be preset, and a stable washing program is also facilitated to be formed.

In the first running state, the difference between the rotating speeds of the inner barrel and the impeller in the reverse rotation is not greater than the difference between the rotating speeds of the inner barrel and the impeller in the same rotation direction and at different speeds. So can form intensity comparatively suitable, comparatively stable rivers improve washing effect and clean rate.

In addition, in this embodiment, when the first operation state and the second operation state are switched to be executed in the same washing process, specific methods may include, but are not limited to, the following specific schemes:

in the scheme 1, the washing machine sequentially performs a first operation state/a second operation state and a second operation state/a first operation state in the same washing process.

In the scheme, the washing machine executes the first operation state once and executes the second operation state once, the first operation state can be executed first and then the second operation state can be executed, and the second operation state can be executed first and then the first operation state can be executed. The operating times of the first operating state and the second operating state can be predetermined as required. For example, after the user selects to run the washing program, the washing machine controls to execute the first operation state for a time T1, and then to execute the second operation state for a time T2, where the time T1 and the time T2 may be the same or different, and may be preset as needed or set by the user.

In the scheme 2, the washing machine controls the first operation state and the second operation state to be switched for multiple times, and the first operation state and the second operation state are alternately executed.

In the scheme, the washing machine executes a first operation state and a second operation state for n times, the first operation state and the second operation state are alternately operated, and the washing machine is switched between the first operation state and the second operation state at regular time or at irregular time. So, the rivers that form are more diversified in the washing process, and two kinds of running state are mutually supported, reach the purpose to the high washing efficiency of clothing and high clean rate, also can greatly reduced to the wearing and tearing of clothing.

In the further scheme, a first operation state and a second operation state are alternately executed in the same washing process, when the washing machine is in the first operation state each time, the impeller and the inner barrel rotate in opposite directions or the impeller and the inner barrel rotate in the same direction and different speeds, and when the washing machine is in the second operation state, the inner barrel and the impeller rotate in the same direction and the same speed and clockwise or anticlockwise.

When the washing machine alternately executes the first running state and the second running state for multiple times, under the first running state, the running states of the inner barrel and the impeller each time can be the same or different, for example, the inner barrel and the impeller rotate reversely each time or move at different speeds in the same direction each time, so that the running is regular, the rotating direction of clothes is regular, and the winding of the clothes can be reduced. Or, the former time inner tub and the impeller counter-rotating, the latter time inner tub and the impeller equidirectional different-speed rotation, so can form more diversified rivers, improve the cleaning rate to the clothing. In the second operation state, the inner tub and the pulsator rotate at the same rotation speed in the same direction, and when the second operation state is switched and executed each time, the inner tub and the pulsator may rotate at the same or different rotation speeds as the previous one, may rotate in a clockwise direction, and may also rotate in a counterclockwise direction.

In a further scheme, in the same washing process, the washing machine alternately executes a first operation state and a second operation state, when the washing machine is in the first operation state each time, the impeller and the inner barrel rotate reversely each time, and the difference value of the rotating speeds of the impeller and the inner barrel is a fixed value. When the second running state is performed, the impeller and the inner barrel rotate clockwise in the same direction and the same speed every time. So the operation of interior bucket and impeller is comparatively regular, and the direction of rotation of clothing is also comparatively regular, can reduce the winding of clothing.

In a further scheme, in the second operation state, the impeller and the inner barrel rotate in the same direction, the rotating speed is V1, and the V1 is not less than the smaller value of the rotating speed of the inner barrel and the impeller in the first operation state. Therefore, the washing efficiency and the washing ratio of the clothes can be improved, the abrasion of the clothes can be reduced, the soft washing can be realized, and the requirements of users can be met.

As an embodiment of the present embodiment, the present embodiment provides a control method of a washing machine in which a washing course operates in a first state, or operates in a second state, or operates in both the first state and the second state. In the first running state, the inner tub and the pulsator are in a relative motion state while rotating, and in the second running state, the inner tub and the pulsator are in a relative rest state while rotating.

In this embodiment, both can add the second running state in the washing process of the ordinary washing procedure of current washing machine, also can set up the gentle washing mode alone on current washing machine, increase the gentle washing mode, carry out the gentle washing process alone. When the user selects the general washing program or the gentle washing mode, the washing machine switches the first operation state and the second operation state or independently executes the second operation state.

Specifically, this embodiment can set up the gentle washing procedure alone on the basis of current washing machine procedure, increases the washing procedure that the user can select, richens the washing machine procedure, promotes user's experience, specifically includes:

in order to facilitate the selection of a user, the existing washing machine comprises a common washing program, a quick washing program and the like, and further comprises a soft washing program and a strong washing program, and in the washing process of the soft washing program, the washing machine can only execute the second operation state or can switch to execute the first operation state and the second operation state; in the washing process of the powerful washing program, the washing machine executes a first running state, and in the running process, the inner barrel and the impeller rotate reversely to form powerful water flow, so that the washing effect is improved.

The soft washing program is additionally added on the basis of the existing washing machine, and aiming at the clothes with soft texture, when a user selects the soft washing program and operates the soft washing program, the washing machine can only execute the second operation state independently, the inner barrel and the impeller can rotate in the same speed and the same direction according to the clockwise direction and/or the anticlockwise direction, and when the user selects the strong washing program next time, the washing process is switched to the first operation state to execute the washing process. Gentle washing procedure also can switch at first running state and second running state, makes stronger rivers and the operation of switching of gentle rivers, reaches abundant washing rivers, improves the washing effect, avoids the purpose of clothing deformation.
