Description
Technical Field
The invention relates to the technical field of washing machines, in particular to a washing machine dehydration control method and a washing machine using the same.
Background
Firstly, after the washing machine finishes a dehydration procedure, clothes still drip water; secondly, the washing machine may be displaced and make a loud noise during the dehydration process. The analysis shows that the main reasons for the problems are as follows: 1) the development trend of the existing washing machine is that the volume is smaller and smaller, in order to improve the volume utilization rate of a washing machine roller, the gap between an outer barrel and an inner wall of the existing washing machine is smaller and smaller, so that the outer barrel is easy to touch the inner wall of the washing machine in the high-speed dehydration process, and the noise and displacement of the washing machine are caused. 2) Some high-end clothes are washed by a machine, and a fine washing bag is frequently used. This causes a large eccentricity in the dewatering process and is not balanced at high speed dewatering. 3) Textiles such as down jackets, pillows and the like have large water absorption capacity, are difficult to be uniformly distributed in the roller due to the shape and the like, and cannot be balanced in the high-speed dehydration process. In order to avoid displacement and loud noise, the washing machine continuously tries to rebalance the load until the set time is used up, so that the clothes taken out by a user usually drip; and if the washing machine chooses to forcibly go up high speed, serious shifting and noise conditions may result.
Specifically, as shown in fig. 1, each spinning speed corresponds to a maximum allowable eccentricity value for a particular washing machine. Generally, the minimum final spin speed of most programs of the drum washing machine is 800 rpm, and the eccentricity value of the washing machine is firstly tested at a rotation speed of about 100 rpm. If the eccentricity is greater than the maximum allowable eccentricity for a specific rotation speed while the washing machine is still at the rotation speed, the washing machine may be displaced, jumped, noisy and worn rubber window gaskets, and even the window gaskets may give out a mushy smell. The current solutions are: if the measured eccentricity value is greater than the allowable eccentricity value for the final spin-off, the washing machine attempts to redistribute the load and re-test the eccentricity value until the measured eccentricity value is less than the allowable eccentricity value. Therefore, the problem of large eccentricity caused by uneven load distribution can be solved, but under certain conditions, no matter how the load is redistributed, the actually measured eccentricity value is difficult to be smaller than the allowable eccentricity value, so that the clothes cannot be dehydrated normally.

Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The present embodiment provides a preferable dewatering control method for a washing machine to solve the problems of displacement, noise and clothes drying during the dewatering and dewatering processes of the existing washing machine, as shown in fig. 2, the method includes the following steps:
step S1: distributing the load;
after the washing machine enters the dehydration procedure, the load distribution is very uneven and a high eccentricity value is easy to occur due to different clothes materials and water contents or different positions of the clothes, so that the load is firstly uniformly distributed before the washing machine enters the high-speed dehydration.
S2: actual eccentricity value A of test loadFruit of Chinese wolfberry；
In this step, the actual eccentricity value A of the load is testedFruit of Chinese wolfberryIs carried out at a rotation speed of 100 rpm, and the set value A is finally removedFinal (a Chinese character of 'gan')Also tested at 100 rpm. For example: if it is predicted that the final spin speed can be up to 1000 rpm if the eccentricity is 400 g at 100 rpm, and that the actual eccentricity is 350 g at 100 rpm, it is possible to determine a spin speed up to 1000 rpm. The eccentricity value of the load is tested at the rotating speed of 100 revolutions per minute, which shows that the dehydration at the rotating speed of 100 revolutions per minute is not problematic, otherwise, the washing machine cannot test the eccentricity value, and the condition is not in the range discussed in the application.
S3: comparing the actual eccentricity value AFruit of Chinese wolfberryAnd final set value AFinal (a Chinese character of 'gan')If A is large or smallFruit of Chinese wolfberry≤AFinal (a Chinese character of 'gan')Then the water is raised to the final dehydration rotating speed V according to the original dehydration curveFinal (a Chinese character of 'gan')If A isFruit of Chinese wolfberry＞AFinal (a Chinese character of 'gan')Then, judge A from low to highFruit of Chinese wolfberryAnd each low speed set value AxIf A is large or smallFruit of Chinese wolfberryLess than or equal to a certain AxThen use the AxCorresponding speed VxOperating for a certain time, wherein the time is preferably 0.5-3 minutes, and returning to the step S1;
it is to be noted that, for a specific washing machine, the final spin speed V is for each spinFinal (a Chinese character of 'gan')Corresponding to a maximum allowable eccentricity value, i.e. final set value AFinal (a Chinese character of 'gan'). Final set value A in this exampleFinal (a Chinese character of 'gan')Has a minimum value of A800Corresponding final take-off speed VFinal (a Chinese character of 'gan')At 800 rpm. Of course, the set value A is finally released according to the requirementTerminalCan also be provided with A1000、A1200、A1400And A1600And A is800＞A1000＞A1200＞A1400＞A1600Since the larger the eccentricity value is, the lower the corresponding drum rotation speed is, the final take-off set value A is set as aboveFinal (a Chinese character of 'gan')Corresponding final disengaging rotation speed VFinal (a Chinese character of 'gan')Respectively 1000 rpmClocks, 1200 rpm, 1400 rpm and 1600 rpm, which can be selected according to the use condition of the user.
Further, in step S3, if aFruit of Chinese wolfberry＞AFinal (a Chinese character of 'gan')"after that, step S31 is also provided.
Step S31: judging whether the preset dehydration time is reached, if so, finishing the dehydration, otherwise, continuing the subsequent procedures, namely judging A from low to highFruit of Chinese wolfberryAnd each low speed set value AxOf (c) is used.
Preferably, the low speed set value A is adopted in the inventionxComprises A400And A200And A is200＞A400＞A800Likewise, A400And A200The corresponding rotational speeds were 400 rpm and 200 rpm, respectively. In this step "from Low to high" AFruit of Chinese wolfberryAnd each low speed set value AxThe size of (a) is specifically: first, judge AFruit of Chinese wolfberryAnd A400If A is large or smallFruit of Chinese wolfberry≤A400Then run at 400 rpm for 1 minute to allow the load to shed a significant portion of the water before redistribution; if AFruit of Chinese wolfberry＞A400Then, determine AFruit of Chinese wolfberryAnd A200If A is large or smallFruit of Chinese wolfberry≤A200Then run at 200 rpm for 1 minute, also can strip some water in the load, then redistribute; if AFruit of Chinese wolfberry＞A200Then the dehydration was performed for 1 minute at 100 rpm and then the redistribution was performed.
As can be seen from the above process, the time for the washing machine to dehydrate at a lower rotation speed is 1 minute each time in the present embodiment, because a better effect can be achieved by dehydrating for 1 minute at a low rotation speed; and because the total dehydration time is generally fixed, if the dehydration time at the stage is too long, the dehydration time after the set final dehydration speed is reached can be influenced.
S4: maintaining the final disengaging speed VFinal (a Chinese character of 'gan')Dehydrating;
s5: it is determined whether the set dehydration time has been reached, and if so, the dehydration is terminated, otherwise, the process returns to step S4.
When the washing machine tests the actual eccentricity value AFruit of Chinese wolfberryGreater than the final set value AFinal (a Chinese character of 'gan')When in use, the load is not directly redistributed, but the water is firstly dehydrated at a low speed for a period of time, and part of water in the load is firstly dehydrated, so that the actual eccentricity value A is naturally reducedFruit of Chinese wolfberrySo that the actual eccentricity value A after redistributionFruit of Chinese wolfberryLess than the final set value AFinal (a Chinese character of 'gan')The probability of (a) is greatly increased. If the actual eccentricity value A is presentFruit of Chinese wolfberryIs less than the final set value ATerminalThe dehydration at a specific rotating speed is finished according to the original dehydration curve; if not, the low speed and test procedure is resumed until the time to dehydrate is exhausted.
In addition, the invention also provides a drum washing machine which carries out dehydration by using the dehydration control method.
The method judges according to the sequence that the eccentricity values gradually increase (namely, the speed is from high to low), compares the actual eccentricity value with certain low-speed eccentricity values, and then selects proper rotating speed and dehydration curve for dehydration, and has the advantages of few test steps, quick reaction and high efficiency; the washing machine firstly carries out low-speed dehydration under the condition of high eccentricity value, thereby effectively reducing the collision and vibration between the inner and outer cylinders of the washing machine and the outer wall of the washing machine, avoiding the phenomena of displacement and noise in the dehydration process of the washing machine, and simultaneously improving the dehydration efficiency.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
