Description
Technical Field
The invention belongs to the field of washing machines, and particularly relates to a dehydration control method of a multi-drum washing machine and the washing machine.
Background
The drum washing machine is a trend of domestic application, and the washed clothes are clean and do not damage the clothes. Currently, drum washers and dryers are available on the market with only one washing tub. Along with the improvement of the quality of life of people, the hygiene consciousness is gradually improved, and particularly in the aspect of household clothes washing, more and more people wash clothes separately. For example, the inner and outer clothes are washed separately, the infant and adult clothes are washed separately, the clothes with different colors are washed separately or a small amount of clothes are washed in time. The existing washing machine is adopted to meet the mode, so that a large amount of energy and water can be wasted, and the requirement of a user on sanitation is difficult to meet. Many households may require more than one drum washing machine, but purchasing two or more washing machines to meet the demand not only increases the cost, but also causes a large space-consuming inconvenience.
Because of the limitation of the residential area, a plurality of drum washing machines occupy a large using space, so that the application of the drum washing machine has a great prospect. The double-drum washing and drying machine can meet the requirements, the cost can be fully controlled, and the problem of waste of energy, water and space is solved. The reasonable double-roller design is arranged up and down, which is convenient for saving space, but brings the problems of controlling the using power of the whole machine and the like. Meanwhile, the operation mode of the drum washing machine determines that there is a large vibration problem during the dehydration, and the vibration problem is particularly serious for the dual drum. Particularly, when the machine is used for dewatering at high speed, the strong vibration of the whole machine can occur, and the use stability and the service life of the machine are seriously influenced.
Therefore, in the current double-drum washing machine, in consideration of the vibration problem during the dehydration of the two drums, the two drums cannot be dehydrated simultaneously, and only after one drum finishes the dehydration, the other drum can start the dehydration, but the time for washing and dehydration is prolonged, and the use convenience of users is reduced.
The present invention has been made in view of this situation.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a dehydration control method of a multi-drum washing machine and the washing machine, which can solve the problem of overlarge amplitude of the existing multi-drum washing machine when all drums dehydrate simultaneously through a software control system.
In order to realize the purpose, the invention adopts the following technical scheme:
a dehydration control method of a multi-drum washing machine comprises a first washing drum, a second washing drum and a control system, wherein when the first washing drum and the second washing drum simultaneously run a dehydration program, the control system adjusts the rotating speed of the first washing drum and/or the second washing drum, and the overall amplitude of the washing machine during dehydration is reduced.
Further, before the first washing drum executes the dehydration program, whether the second washing drum executes the dehydration program is judged; if not, the first washing drum controls the washing drum to execute a dehydration program at a first rotating speed; if yes, the first washing drum adjusts the washing drum to execute the dehydration program at a second rotating speed which is the same as or different from the first rotating speed.
Further, before the first washing drum executes the dehydration program, the second washing drum executes the dehydration program, the first washing drum executes the dehydration program at a second rotation speed different from the first rotation speed, and after the second washing drum finishes the dehydration, the first washing drum controls the washing drum to execute the dehydration program at the first rotation speed.
Further, the first rotation speed is a spin-drying program rotation speed set for the first washing drum according to the laundry attribute of the laundry to be dehydrated;
preferably, the clothing attribute includes a material and/or a weight of the clothing.
Further, the second rotation speed is not greater than the first rotation speed;
preferably, the first rotating speed and/or the second rotating speed are different rotating speed gears;
preferably, the speed gear comprises 300 rpm, 600 rpm, 800 rpm, 1200 rpm, 1500 rpm.
Further, the second rotating speed is adjusted according to the eccentricity of the clothes to be dehydrated in the first washing drum in the washing drum, and the magnitude of the second rotating speed is inversely related to the magnitude of the eccentricity.
Further, the second rotating speed is adjusted according to the vibration amplitude of the whole washing machine, and the magnitude of the second rotating speed is inversely related to the magnitude of the vibration amplitude.
Further, the second rotating speed is the dewatering rotating speed of the first washing drum which meets the requirement of minimizing the overall amplitude of the washing machine according to the initial and/or real-time weight of clothes in the first washing drum during dewatering, the eccentric amount of the clothes to be dewatered in the first washing drum in the washing drum, and/or the vibration amplitude of the whole washing machine.
Further, before the first washing drum executes the dehydration program, whether the second washing drum executes the dehydration program is judged; if not, the second washing drum keeps the original rotating speed to continuously execute the dehydration program; if yes, the second washing drum adjusts the washing drum to execute the dehydration program at a rotating speed different from the original rotating speed.
A washing machine, using the dehydration control method of the multi-drum washing machine as any one of the above, comprises a first washing drum and a second washing drum, and a control system for controlling the rotation speed of the first washing drum and/or the second washing drum during dehydration, wherein when the first washing drum and the second washing drum simultaneously run a dehydration program, the control system adjusts the rotation speed of the first washing drum and/or the second washing drum;
preferably, the control system comprises an amplitude sensing device and a rotation speed adjusting device which are electrically connected with each other; the amplitude induction device is used for inducing the amplitude of the whole washing machine during working; the rotating speed adjusting device is connected with the first washing drum and/or the second washing drum in a circuit mode and controls the rotating speed of the first washing drum and/or the second washing drum.
After the technical scheme is adopted, compared with the prior art, the invention has the following beneficial effects.
The invention relates to a dehydration control method of a multi-drum washing machine and the washing machine, which do not adopt the control method of alternately dehydrating washing drums adopted in the common design, but adjust the rotating speed of a first washing drum and/or a second washing drum by using a control system, so that the washing drums of the multi-drum washing machine realize simultaneous dehydration and simultaneously greatly reduce the overall amplitude of the washing machine during dehydration.
The washing drums of the invention have different rotating speeds corresponding to different gears, and the washing drums select different rotating speeds to execute the dehydration program aiming at the condition that whether other washing drums are executing the dehydration program or not, thereby not only meeting the requirements that the washing drums realize normal dehydration according to the existing rotating speed when single-drum dehydration is executed, but also meeting the requirement that the washing drums reduce the overall amplitude when other drums are dehydrating, and finally realizing the simultaneous dehydration of a plurality of drums.
According to the invention, after the second washing drum finishes dewatering, the first washing drum resumes the default rotating speed or executes the dewatering program at the new rotating speed, so that the dewatering control is more flexible, the whole dewatering process of the first washing drum is completed in an optimal mode, and the dewatering time of the first washing drum is shortened. The default rotating speed is the first rotating speed in the invention, which is the rotating speed of the dehydration program set according to the clothes attribute of the clothes to be dehydrated, and can meet the requirement of personalized dehydration of the clothes, so that the dehydration process can meet the basic dehydration requirement and reduce the damage to the clothes as much as possible.
The invention provides various realization modes for self rotating speed regulation when the first washing drum detects that the second washing drum is executing the dehydration program, such as: the method for controlling the dewatering rotating speed of the washing drum is characterized in that the rotating speed is simply reduced by utilizing a gear adjusting mode, or the rotating speed is adjusted according to the eccentricity of clothes to be dewatered in the washing drum, or the rotating speed is adjusted according to the vibration amplitude of the whole washing machine, and the like. Due to the change of the speed regulation reference of the method, the rotating speed of the first washing drum can meet the requirements of low amplitude and stable operation of the whole washing machine.
Meanwhile, the invention also indicates that the rotation speed regulation is not only aimed at the washing drum for dehydration at the rear part, but also is suitable for the washing drum for dehydration at the front part, so that the whole rotation speed regulation mode is more flexibly combined. Because different control systems of the washing machines are different, some washing machines are convenient to control the rotating speed of a washing drum for later dehydration, and some washing machines are easier to control the rotating speed for earlier dehydration.
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 to 2, the present invention discloses a dehydration control method for a multi-drum washing machine and a washing machine, wherein the washing machine comprises a first washing drum, a second washing drum and a control system, and when the first washing drum and the second washing drum simultaneously run a dehydration program, the control system adjusts the rotation speed of the first washing drum and/or the second washing drum, so as to reduce the overall amplitude of the washing machine during dehydration. The invention can solve the problem of overlarge amplitude of the existing multi-drum washing machine when all drums dehydrate simultaneously through a software control system, can be realized without detecting various balance weights or adding excessive auxiliary equipment, has small change work for the existing washing machine, enables the multi-drum simultaneous dehydration to be possible, reduces the overall processing time of clothes, improves the washing efficiency and improves the satisfaction rate of users.
Example 1
As shown in fig. 1 and 2, the present embodiment discloses a dehydration control method of a multi-drum washing machine. The washing machine of the embodiment comprises a first washing drum 1, a second washing drum 2 and a control system, wherein when the first washing drum 1 and the second washing drum 2 simultaneously run a dehydration program, the control system adjusts the rotating speed of the first washing drum 1 and/or the second washing drum 2, and the overall amplitude of the washing machine during dehydration is reduced.
In the present embodiment, each washing drum has a plurality of selectable different speed steps corresponding to different speeds, and these speed steps include 600 rpm, 800 rpm, 1200 rpm, or 1500 rpm.
Before the first washing drum executes the dehydration program, judging whether the second washing drum executes the dehydration program; if not, the first washing drum controls the washing drum to execute a dehydration program at a first rotating speed; if yes, the first washing drum adjusts the washing drum to execute the dehydration program at the rotation speed of the second rotation speed. The second rotation speed is the dehydration rotation speed of the first washing drum controlled by the system according to the current motion state, and can be the same as or different from the first rotation speed. The first rotating speed is a dehydration program rotating speed set by the washing drum according to the clothes attribute of the clothes to be dehydrated; preferably, the clothing attribute includes a material and/or a weight of the clothing. In this embodiment, the first rotation speed is automatically set by the washing machine having the laundry attribute identification device, and the washing machine automatically sets the first rotation speed by the laundry attribute of the laundry to be dehydrated identified by the laundry attribute identification device. In other embodiments, the first rotation speed may also be a rotation speed manually set by a user according to the laundry property of the laundry to be dehydrated.
In this embodiment, the first rotation speed corresponds to a spin-drying rotation speed determined by the property of the laundry, and the first rotation speed focuses on the spin-drying requirement of the laundry, that is, the rotation speed gear matched by the washing machine according to the property of the laundry. At the first rotation speed, the washing drum can provide an optimal dehydrating operation for the laundry.
In this embodiment, before the first washing drum performs the spin-drying process, if it is detected that the second washing drum is performing the spin-drying process, the first washing drum performs the spin-drying process at a second rotation speed, which is different from the first rotation speed, and after the second washing drum finishes the spin-drying process, the first washing drum controls the washing drum to perform the spin-drying process at the first rotation speed. The mode has the advantages that the number of the dehydration gears configured for the washing machine can be reduced, and as long as the second washing drum finishes the dehydration program, the first washing drum restores the default optimal dehydration rotating speed, thereby achieving better dehydration effect.
In other embodiments, the first spin speed is a default spin speed of the washing machine.
The second rotational speed in this embodiment is not greater than the first rotational speed; further, the first rotating speed and/or the second rotating speed are different rotating speed gears. That is, in the embodiment, before the first washing drum performs the spin-drying process, it is detected that the second washing drum is performing the spin-drying process, and the spin-drying speed is actively reduced. The vibration amplitude of the first washing drum is reduced in such a way that the first washing drum is suitable for a small amount of clothes and the clothes are relatively uniform. In this case, the vibration amplitude of the washing drum is positively correlated with the rotation speed, i.e. the vibration amplitude can be reduced by reducing the rotation speed.
Example 2
This embodiment is a supplement to embodiment 1, in which the second rotation speed is adjusted according to the eccentricity of the laundry to be dehydrated in the first washing drum, and the magnitude of the second rotation speed is inversely related to the magnitude of the eccentricity. The second rotation speed of the present embodiment is not simply a certain rotation speed gear smaller than the first rotation speed, but is a dynamic variation value adjusted according to the eccentricity of the laundry to be dehydrated in the first washing drum. The second rotation speed is changed mainly to adapt to the change of the eccentric amount in the washing drum, so that the washing drum can be dehydrated at the rotation speed as high as possible in a section lower than the first rotation speed as the second rotation speed under the condition that the shaking amount meets the application requirement, so that the first washing drum can remove as much water as possible in the dehydration state at the second rotation speed, and finally, the whole dehydration time is not excessively prolonged.
Example 3
The present embodiment is a supplement to the above-mentioned embodiments, in which the second rotation speed is adjusted according to the vibration amplitude of the whole washing machine, and the magnitude of the second rotation speed is inversely related to the magnitude of the vibration amplitude. The second rotation speed in this embodiment is not focused on parameters such as the washing drum itself or the laundry property, but the vibration amplitude of the whole washing machine. In the process of dewatering of the washing machine, in a certain speed interval, the higher the rotating speed is, the smaller the shaking generated by the washing drum is; meanwhile, for power output, the dehydration of the first washing drum and the dehydration of the second washing drum are two dehydration processes which respectively and independently run, and corresponding vibration with certain frequency is generated in the dehydration processes. The vibration amplitude of the whole washing machine is not the result of the vibration of a certain washing drum alone, but the superposition of the two. In fact, when the second rotation speed is operated at a higher speed than the first rotation speed, the vibration amplitude of the washing machine as a whole may be reduced due to the destructive effect of the mutual vibrations. Therefore, in the embodiment, the second rotation speed is not limited to the interval not higher than the first rotation speed, but the vibration amplitude of the whole washing machine is taken as the adjustment reference, and the control system adjusts the magnitude of the second rotation speed to be inversely related to the magnitude of the vibration amplitude, so that the second rotation speed can be dynamically adjusted along with the vibration amplitude of the whole washing machine. The change of the reference object for speed regulation makes the rotating speed of the first washing drum meet the requirement of low amplitude and stable operation of the washing machine
Example 4
This embodiment is a supplement to the above-described embodiment. In this embodiment, the second rotation speed is the dehydration rotation speed of the first washing drum which is calculated according to the initial and/or real-time weight of the clothes to be dehydrated in the first washing drum of the washing machine during dehydration, and/or the eccentric amount of the clothes to be dehydrated in the first washing drum in the washing drum, and/or the vibration amplitude of the whole washing machine, and meets the requirement of minimizing the whole amplitude of the washing machine. The washing machine in this embodiment has an arithmetic unit and a sensor. The sensor monitors the initial weight of the clothes in the first washing drum during the dehydration of the clothes, and/or the eccentricity of the clothes to be dehydrated in the first washing drum in the washing drum, and/or the vibration amplitude of the whole washing machine, wherein the initial characteristics of the initial weight and the eccentricity of the clothes determine the resonance frequency of the washing machine at the moment. And the calculating unit of the washing machine calculates a second rotating speed which can avoid the resonance frequency of the washing machine according to the correlation between the rotating speed monitored by the sensor and the vibration amplitude of the whole washing machine and the resonance frequency determined by the initial characteristic, and controls the washing drum to dewater at the second rotating speed, so that the resonance caused by dewatering of the washing machine is avoided.
In order to further modify the result of the second speed calculation of this embodiment, in other embodiments, the sensor monitors the real-time weight of the laundry in the first washing tub during the dewatering process and applies this weight to the second speed calculation. In such an embodiment, the characteristic that the weight of the clothes is changed continuously when the dehydration program is executed is fully considered, and the rotating speed corresponding to the current resonance frequency is calculated in real time, so that the control of the second rotating speed is more accurate, and a better shock absorption effect can be achieved.
Example 5
This embodiment is a supplement to the above-described embodiment. In this embodiment, before the first washing drum executes the dehydration program, the second washing drum executes the dehydration program, and after the second washing drum finishes the dehydration, the first washing drum controls the washing drum to execute the dehydration program at a third rotation speed, where the third rotation speed is different from the first rotation speed and the second rotation speed;
preferably, the third rotational speed is greater than the second rotational speed.
After the first washing drum of the invention executes the dehydration program by using the second rotating speed, the dehydration process of the first washing drum can be selected in various ways after the second washing drum finishes dehydration. A first washing drum as described in embodiment 1, after performing a dehydration process using a second rotation speed, controlling the washing drum to perform the dehydration process at the first rotation speed; in the second case, the first washing drum keeps the rotation speed after the second rotation speed is used for executing the dehydration program until the dehydration is finished; in the third case, after the first washing drum performs the spin-drying process at the second rotation speed, the first washing drum is controlled to perform the spin-drying process at the third rotation speed.
The third rotating speed is greater than the second rotating speed or greater than the first rotating speed, namely after the second washing drum finishes the dewatering process, the first washing drum selects a higher rotating speed to finish the rest dewatering work, and the advantage is that the delay time of the first washing drum in the simultaneous dewatering of multiple drums can be reduced to the maximum extent, so that the whole dewatering time can be reduced, and the dewatering efficiency is improved.
Example 6
This embodiment is another alternative to any of the embodiments described above. In this embodiment, before the first washing drum executes the dehydration program, it is determined whether the second washing drum is executing the dehydration program; if not, the second washing drum keeps the original rotating speed to continuously execute the dehydration program; if yes, the second washing drum adjusts the washing drum to execute the dehydration program at a rotating speed different from the original rotating speed. The present embodiment is different from the above embodiment in the rotation speed adjusting scheme, and mainly adopts a method for realizing the technical effect of low amplitude of the whole machine by adjusting the rotation speed of the washing drum after the dewatering, but realizes the technical effect by adjusting the rotation speed of the washing drum before the dewatering. The embodiment enables the whole combination of the rotating speed adjusting modes to be more flexible. Because different control systems of the washing machines are different, some washing machines are convenient to control the rotating speed of the later dewatering, and some washing machines are easier to control the rotating speed of the earlier dewatering.
In the above embodiment, due to the variation of the rotation speed during the dehydration, the dehydration time of each washing drum is adjusted accordingly in order to meet the dehydration requirement.
