Abstract
The invention discloses a method for removing scale in a washing machine, which sprays water to the outer wall of an inner barrel and the outer side of the bottom of the inner barrel of the rotating washing machine through a water spraying port arranged on an outer barrel of the washing machine at a preset time interval in the dewatering process of the washing machine, washes and removes a small amount of dirt formed on each wall surface after the last washing, prevents the dirt on each wall surface from being further accumulated, and keeps the dirt degree at a slight degree.
Description
Technical Field
The invention relates to the field of washing devices, in particular to a method for removing scale of a washing machine.
Background
Washing machines have entered thousands of households, but full-automatic washing machines have the common problem of scale deposition in the interlayer of the washing barrel. As the use time increases, a lot of dirt is formed on the hidden portion between the inner and outer tubs of the washing machine. The dirt is formed by that foam and low-concentration rinsing water (still containing a small amount of detergent and dirt) are attached to each part in the washing tub after the washing is finished, and dissolved substances contained in the foam and the low-concentration rinsing water are separated out and attached to the surface of each washing part to form an extremely thin dirt layer after the water is naturally evaporated. The dirt layer can absorb water and soften in the subsequent washing process, but no friction substance exists in the interlayer, so the dirt attached in the interlayer can not be removed in the subsequent washing, the dirt layer is continuously overlapped and accumulated along with the increase of the washing times, the dirt layer is invisible when being thinned and thickened, and finally the dirt layer is seen. They are not only easy to breed bacteria, but also can partially fall off in the washing process to influence the washing effect, and generate the phenomenon of 'sewage washing'.
Disclosure of Invention
The technical problem to be solved by the present invention is to provide a method for removing the dirt in the washing machine in time, preventing the dirt from further accumulating, and keeping the dirt existing in each space inside the washing tub at a slight degree, aiming at the above-mentioned defects of the prior art.
The principle of centrifugal drying is as follows: the dehydration rate has a functional relation with the rotating speed and the diameter of the inner barrel, and has no relation with the external water injection quantity, and the inner barrels with different diameters have respective dehydration balance point rotating speed r 1. When the rotating speed of the inner barrel is higher than the rotating speed r1 of the dehydration balance point, the water sprayed through the dehydration holes can be immediately thrown out, so that the water spraying to the outer side surface of the inner barrel can not increase the moisture content of the clothes in the barrel when the rotating speed of the inner barrel is higher than r 1.
The industry knows the knowledge that: the rated rotating speed r2 of the dehydration stage is greater than the rotating speed r1 of the dehydration balance point of the machine.
A washing process of a washing machine comprises a plurality of dehydration steps, wherein the non-final dehydration step generally requires 2-3 minutes, and the final dehydration step generally requires 4-5 minutes. In any one or more dewatering processes in the washing process, water is sprayed to the outer wall surface of the rotating inner barrel through the water spraying port to flush dirt formed on various parts of the washing barrel, so that the dirt in the washing machine cannot be further accumulated.
For a better understanding of the method, reference is made to the accompanying figure 1:
the technical scheme adopted by the invention is as follows: a method for removing scale in a washing machine, comprising: spraying water to the outer side of the inner barrel wall and/or the outer side of the bottom of the inner barrel of the washing machine for a preset time period from the time when the inner barrel of the washing machine starts to rotate to the time when the rotation reaches a preset time t 1. The predetermined time period is 0.2-2 minutes.
Further, in the non-last dewatering stage, the preset time t1 is when the inner barrel stops rotating and/or in the last dewatering stage, and the preset time t1 is when the rotating speed of the inner barrel is reduced to a preset value r.
Furthermore, the preset value r is greater than or equal to the dehydration hole, the water sprayed in through the dehydration hole is immediately thrown out and does not enter the inner barrel to soak the clothes, and the corresponding dehydration balance point rotating speed r1 is smaller than or equal to the rated rotating speed r2 of the washing machine in the dehydration stage.
Further, the method for removing the scale of the washing machine comprises the following steps: the water spraying port starts to spray water 0.2-2 minutes before the dehydration program of the washing machine runs to the power-off of the dehydration motor, and stops spraying water when the power-off of the dehydration motor is realized.
Further, the method for removing the scale of the washing machine comprises the following steps: and the water spray opening starts to spray water when the dehydration program of the washing machine runs to the inner barrel reaches the dehydration rated rotating speed, and the water spray is stopped after 0.2-2 minutes of delay.
Further, the method for removing the scale of the washing machine comprises the following steps: the water spraying port starts spraying water when the inner barrel of the washing machine starts rotating, and the water spraying is stopped after 0.2-2 minutes.
Further, the method for removing the scale of the washing machine comprises the following steps: in the non-last dewatering stage, the water spraying port starts to spray water at any time in the period from the time when the inner barrel of the washing machine starts to rotate to the time when the inner barrel stops rotating for 0.2-2 minutes, and the water spraying is stopped after 0.2-2 minutes.
Further, the method for removing the scale of the washing machine comprises the following steps: in the last dewatering stage, the water spraying port starts to spray water at any time within 0.2-2 minutes before the inner barrel of the washing machine starts to rotate until the rotating speed of the inner barrel is reduced to a preset value r, and the water spraying is stopped after 0.2-2 minutes.
Further, the method for removing the scale of the washing machine comprises the following steps:
the water spray opening is arranged on the outer barrel wall and/or the outer barrel bottom of the washing machine;
a self-cleaning program that performs any one and/or more of the methods and/or steps described above.
In the preset time period of the dehydration process, the water is sprayed to the outer wall surface and/or the bottom surface of the inner barrel through the water spraying ports for 0.2-2 minutes, the sprayed water flow scours the outer wall surface and/or the bottom surface of the inner barrel, meanwhile, the water flows through the rotating inner barrel to be beaten and splashed to all the wall surfaces in the interlayer, and dirt left after the last washing is washed and removed. The flushing water flow and the fallen dirt are discharged out of the machine together with the drainage of the inner barrel. Considering the requirement of the last dehydration on the moisture content of the clothes, the washing time in the last dehydration stage is made as follows: a further limitation of "the water spray must be stopped before the inner tub rotation speed drops to the preset value r". Therefore, the method has the characteristics of not increasing the working time of the washing machine, not influencing the dewatering effect and not changing the original structure of the washing machine.
The invention has the technical effects that: the interlayer is washed in the dehydration process, dirt left after the last washing is removed, the dirt is prevented from being further accumulated in the washing machine, and the effect that the scale deposit of the interlayer of the full-automatic washing machine is always kept at a slight degree is achieved.
