Example IV
The embodiment provides a control method of a washing machine, which specifically includes: the washing process of the washing machine comprises the state that the inner barrel and the impeller are relatively static when rotating.
The washing machine in this embodiment is a washing machine with 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 impeller is arranged at the bottom of the inner barrel. In the washing process of a general washing machine, the pulsator rotates to drive water flow to run so as to wash and clean clothes, and for a double-power washing machine, the inner barrel and the pulsator can rotate in the washing process at the same time, and the generated water flow is more powerful than that generated when the pulsator only rotates, but only comprises single washing water flow, so that the washing effect is limited, and the improvement is not obvious.
The embodiment can realize that the inner barrel and the impeller are in a relatively static state when rotating in the washing process, so that the water flow form of the inner barrel and the impeller rotating in the same direction and at the same speed is increased, the diversity of washing water flow is increased, the gentle washing is realized, and the washing and protecting effects on clothes are improved.
Specifically, the washing process of the washing machine comprises a first running state and/or a second running state; 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 relative static state when rotating.
In a first operating state, the inner tub and the pulsator are in a relative motion state including: the inner barrel and the impeller rotate reversely, and the rotating speeds are the same or different. In the second operating state, the inner tub and the pulsator being in a relatively stationary state includes: the inner barrel and the impeller rotate in the same direction and at the same speed; specifically, the inner tub and the pulsator simultaneously rotate in a clockwise direction or a counterclockwise direction at the same rotation speed.
In the same washing process, the washing machine can keep the inner barrel and the pulsator in a relatively static state when rotating all the time; the relative motion state can be kept all the time; the relative static state can be executed only in part of time, the relative motion in part of time can be realized, the different states can be switched, 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 course, 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 perform only the first operation state, and the inner tub and the pulsator perform relative movement, perform the same-direction different-speed or reverse rotation movement, so that a stronger water flow may be formed, which is beneficial to improving the washing effect.
In addition, in the same washing process, the inner barrel and the impeller can keep a relatively static state all the time when only the second running state is executed, that is to say, the inner barrel and the impeller rotate at the same speed and in the same direction in the washing process, so that new water flow is formed, and the washing machine is favorable for gently washing soft clothes.
The conditions of the inner barrel and the impeller rotating in the same direction at the same speed in the washing process comprise:
case 1: the inner barrel and the impeller always rotate in the same direction and at the same speed in the clockwise direction in the washing process;
case 2: the inner barrel and the impeller always rotate in the same direction and speed in the anticlockwise direction in the washing process;
case 3: the inner tub and the pulsator are switched between clockwise rotation at the same speed and counter clockwise rotation at the same speed during the washing process.
In either case, in the same washing process, the inner barrel and the pulsator are always in a relatively static state, so that the water flow mode of the inner barrel and the pulsator rotating in the same direction and at the same speed is realized, the washing can be performed more gently, and the washing and protecting effects on soft clothes are improved.
As an implementation manner of the present embodiment, the present embodiment provides a control method of a washing machine, which specifically includes:
the washing process of the washing machine comprises a first running state and a second running state, and the first running state and the second running state can be switched;
in the first running state, the inner barrel and the impeller are in a relative motion state when rotating, and in the second running state, the inner barrel and the impeller are in a relative static state when rotating.
In this scheme, can switch between two kinds of running states in the washing process, can produce different washing rivers under two kinds of running states, so increase the variety of washing rivers, can improve washing efficiency and the washing ratio to the clothing.
Specifically, the two running 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 moving; when the inner barrel and the impeller are in a relatively 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 drawing force applied to the clothes is small, the abrasion to the clothes can be reduced, and the soft washing is realized; and under the state of inner tub and impeller relative motion, the rivers intensity that forms is great, so, and these two states switch the washing, mutually support, can enough improve the washing effect, can also reach the effect of protection clothing, reduce clothing wearing and tearing deformation, satisfy user's demand.
In the washing process, in the second operation state, the inner tub and the pulsator are in a relatively stationary state, including: the inner barrel and the impeller rotate in the same direction and at the same speed. The inner barrel and the pulsator can rotate in the clockwise direction at the same time at the same rotating speed, and can also rotate in the anticlockwise direction. Thus, although the inner barrel and the impeller are rotating, the inner barrel and the impeller are completely synchronous in movement, the inner barrel and the impeller are relatively static, water flow formed in the inner barrel flows in the same direction at the same stable speed, the clothes in the inner barrel move along with the water flow, the pulling force applied to the clothes is minimum, and the soft washing process is more suitable for the clothes which are easy to deform such as silk, wool and the like.
And under the first running state, the mode that interior bucket and impeller are in relative motion state can include multiple, and the different modes can form comparatively different rivers that intensity is big, and the rivers that first running state and second running state formed in this embodiment are mutually supported and are washed, and interior bucket and impeller's motion mode can include following several schemes under the first running state:
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 along opposite directions are formed, a stronger rotating water flow is formed at the meeting position of the two water flows, and the clothes are greatly washed, so that the washing effect and the cleaning rate are ensured.
Scheme 2, interior bucket and impeller carry out counter-rotation, and interior bucket and impeller's rotational speed is different simultaneously, and the same with scheme 1 effect, interior bucket and impeller's rotation can form stronger rotatory rivers, causes great washing and pulling force to the clothing, guarantees washing effect and clean rate.
As a preferable scheme, when the inner barrel and the impeller reversely rotate, the rotating speeds are different, and the rotating speed difference value 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, higher washing efficiency can be guaranteed, and damage to the clothes can be avoided.
Scheme 3, under the first running state, interior bucket and impeller syntropy rotate, and interior bucket and impeller rotational speed are different, and when interior bucket and impeller syntropy rotate but different speeds, also can form the great rotatory running water of intensity, guarantee washing efficiency.
Further, the inner barrel and the impeller rotate in the same direction and at different speeds, and the rotating speed difference value of the inner barrel and the impeller is a fixed value or a variable value; thus, water flow with certain strength can be preset, and stable washing procedure can be formed.
In the first running state, the difference of the rotating speeds of the inner barrel and the impeller when the inner barrel and the impeller rotate reversely is not larger than the difference of the rotating speeds when the inner barrel and the impeller rotate in the same direction and at different speeds. Therefore, water flow with proper strength and stable strength can be formed, and the washing effect and the cleaning rate are improved.
In addition, in the present embodiment, when the first operation state and the second operation state are switched to be performed in the same washing process, the specific method may include, but is not limited to, the following specific schemes:
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 course.
In the scheme, the washing machine executes the first running state once and executes the second running state once, and the first running state can be executed first and then the second running state can be executed, and the second running state can be executed first and then the first running state can be executed. The operating times of the first operating state and the second operating state may be preset as needed. For example, after the user selects to run the washing program, the washing machine is controlled to execute the first running state for a time T1, and then execute the second running state for a time T2, where the time T1 and the time T2 may be the same or different, and may be preset or set by the user as required.
Scheme 2, the washing machine controls the first operation state and the second operation state to switch for a plurality of times, and the first operation state and the second operation state are alternately executed.
In the scheme, the washing machine executes the first running state and the second running state for n times, the first running state and the second running state run alternately, and the washing machine switches between the first running state and the second running state at regular or irregular time. Therefore, the water flow formed in the washing process is more diversified, and the two running states are matched with each other, so that the purposes of high washing efficiency and high cleaning rate of clothes are achieved, and the abrasion to the clothes can be greatly reduced.
Further, the first operation state and the second operation state are alternately executed in the same washing process, when the washing machine is in the first operation state each time, the pulsator and the inner tub reversely rotate or the pulsator and the inner tub uniformly rotate at different speeds, and when the washing machine is in the second operation state, the inner tub and the pulsator uniformly rotate at the same speed in a clockwise direction or a counterclockwise direction.
When the washing machine alternately executes the first running state and the second running state for a plurality of times, the running states of the inner barrel and the impeller in the first running state can be the same or different each time, for example, the inner barrel and the impeller rotate reversely each time or move in the same direction and at different speeds each time, so that the running is regular, the rotating direction of the clothes is also regular, and the winding of the clothes can be reduced. Or, the former inner barrel and the impeller reversely rotate, and the latter inner barrel and the impeller rotate at the same direction and different speeds, so that more diversified water flows can be formed, and the cleaning rate of clothes is improved. Under the second running state, the inner barrel and the impeller rotate at the same direction and the same rotating speed, and when the second running state is switched and executed each time, the inner barrel and the impeller can rotate at the same or different rotating speeds as the previous time, can rotate in the clockwise direction and can also rotate in the anticlockwise 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 pulsator and the inner barrel reversely rotate each time, and the rotating speed difference value of the pulsator and the inner barrel is a fixed value. And when the rotary drum is in the second running state each time, the rotary drum and the inner drum rotate in the clockwise direction at the same speed each time. Therefore, the inner barrel and the impeller are regular in running, the rotation direction of clothes is also regular, and the winding of the clothes can be reduced.
Further, in the second running state, the pulsator and the inner barrel rotate in the same direction, the rotating speeds are V1, and the V1 is not smaller than the smaller value of the rotating speeds of the inner barrel and the pulsator in the first running state. Therefore, the washing efficiency and the washing ratio of the clothes can be improved, the abrasion to the clothes can be reduced, the soft washing is realized, and the requirements of users are met.
As an implementation manner of the present embodiment, the present embodiment provides a control method of a washing machine, in which a washing process is operated in a first state, or in a second state, or in both the first state and the second state. 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 relative static state when rotating.
In this embodiment, the second operation state may be added during the washing process of the conventional washing machine, or the soft washing mode may be added to the conventional washing machine alone, and the soft washing process may be executed alone. When the user selects the normal washing program or the soft washing mode, the washing machine switches to execute the first operation state and the second operation state or independently executes the second operation state during the washing process.
Specifically, the embodiment can set a soft washing program independently on the basis of the existing washing machine program, increases the washing programs selectable by a user, enriches the washing machine programs, and improves the user experience, and specifically comprises the following steps:
in order to facilitate the selection of users, 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, wherein in the washing process of the soft washing program, the washing machine can only execute the second running state or can switch to execute the first running state and the second running 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 pulsator reversely rotate to form powerful water flow, so that the washing effect is improved.
The soft washing program is a program additionally added on the basis of the existing washing machine, aiming at soft clothes, when a user selects the soft washing program and operates the soft washing program, the washing machine can singly execute the second operation state, the inner barrel and the pulsator can rotate in the same direction at the same speed according to the clockwise and/or anticlockwise directions, and when the user selects the powerful washing program next time, the washing machine is switched to the first operation state to execute the washing process. The soft washing program can be switched between the first running state and the second running state, so that stronger water flow and softer water flow can be switched for running, the purposes of enriching washing water flow, improving washing effect and avoiding deformation of clothes are achieved.
Therefore, the program of the washing machine not only comprises a common washing program, but also comprises a powerful washing program and a gentle washing program, and a user can independently select a proper washing program according to clothes materials, dirt degree and the like, and can switch between different washing programs/running states, so that the washing program of the washing machine is enriched, washing water flow is enriched, user experience is improved, and the purposes of improving the washing and protecting effects are achieved.
