Technical Field

The invention relates to the technical field of washing machines, in particular to a technology for removing foam and improving cleaning and self-cleaning capabilities and a washing machine.

Background

The main functions of the washing machine are to wash and rinse the laundry. The washing machine has entered into the full-automatic intelligent era at present, but the problem of foam, the problem of unclean rinsing, and the problem of cleaning of the washing machine are always the hard injuries of the current washing machine. No matter how advanced the washing machine, using detergent will appear some foam in normal washing and rinsing process, because its static suspension characteristic can't be discharged smoothly with water, even after dewatering still stay in the washing machine; from the factors of influencing the environment of rinsing, and the like, the method has the influence of foam retention in the washing process, and also has the influence of lack of necessary dehydration in the middle and much carried objects in clothes. The stagnant dirty components such as foam directly influence the subsequent washing process and the sanitation of the washing machine, and the washed clothes often have wet and slippery feeling.

Disclosure of Invention

The present invention is directed to solving the problems of the prior art and to providing a technique for systematically and effectively removing bubbles and improving the washing and self-cleaning ability of a washing machine, and a washing machine.

The technical scheme of the invention is as follows: the novel working process of the washing machine is established in a program linkage mode, the control of the emission and the discharge process is enhanced, the spraying electromagnetic valve and the spraying water pipe are arranged, the foam detection means is cancelled, the foam suspension retention environment is damaged through the sequential and parallel operations of the washing program, the rinsing program, the drainage program, the dehydration program and the spraying program, the mixed discharge of foam and water to be drained is realized in the discharge process, the foam is effectively removed, the washing environment is purified, and the cleaning and self-cleaning capability of the washing machine is improved.

The technical scheme is that the program linkage and the new working process of the washing machine are established, and the new working process comprises the mixed discharge processes of opening a drainage pump in advance for continuous dynamic discharge before the washing and rinsing processes are finished, and starting a dehydration process, a spraying process and the like in a delayed mode, and is called as desorption-spraying mixed discharge for short.

The technical scheme is that the control of the discharge and the discharge process is enhanced, the washing environment is purified, the washing program or the rinsing program is linked with the drainage program aiming at the static suspension retention characteristic of the foam and the objectivity existing in the washing process, the drainage pump is opened in advance when the inner cylinder rotates, the to-be-drained water is reused, the foam is mixed with the drainage water, and the foam is discharged to the maximum extent in the discharge process.

The dewatering program and the spraying program are countermeasures taken aiming at retained foam after primary drainage and sewage foam components contained in clothes.

The dewatering program is started after the washing or rinsing program is finished, the dewatering program is parallel to the drainage program, the sewage foam contained in the clothes is removed in the process of simulating hand washing and wringing, and meanwhile, the removed water has a certain scouring effect, so that the retained foam and the water are mixed and drained again.

The spraying program is a section of water spraying operation parallel to the dewatering program and the drainage program, and the spraying solenoid valve and the spraying water pipe arranged in the washing machine scour the outer side of the inner barrel by means of water inlet pressure, and meanwhile, the retained foam in the outer barrel is also subjected to powerful spraying scouring under the action of the inner barrel, so that the retained foam is further mixed with water, and a third mixed discharge process is realized.

The foam mixing and discharging process is carried out for three times during each time of water discharging, wherein water to be discharged is utilized twice, and water is sprayed once, the new water consumption amount during the period is very small, and the foam mixing and discharging process is completely different from the traditional 'water discharging process after the inner cylinder stops rotating'.

The improvement of the cleaning and self-cleaning capability refers to the mixed discharging of the dewatering and spraying under the linkage of programs, so that the sewage foam entering a new rinsing process is greatly reduced, the clothes are easily rinsed, and the washing machine is self-cleaned while the spraying and defoaming are carried out.

The washing program, the rinsing program, the drainage program, the dehydration program and the spraying program are in linkage action, and the operation parameters such as time nodes and the like need to be optimized.

The specific implementation mode is as follows: starting a draining pump 7 seconds before the washing program or the rinsing program is finished to continuously and dynamically drain water, continuously rotating the inner cylinder, and discharging a large amount of foam and water after mixing; after the washing or rinsing program is finished, starting a dewatering program after 2 seconds of delay, simulating a hand washing and wringing process, and removing the clothes sewage foam in the specified running time of 180 seconds (the running time of the last dewatering program is not set separately), wherein the foam is continuously discharged after the inner drum rotates to mix with water; the self-starting dehydration program delays for 150 seconds, the spraying electromagnetic valve is opened, the spraying electromagnetic valve is closed after the water is sprayed for 8 seconds under the water supply pressure (the instant rotating speed of the inner cylinder is not lower than 700 revolutions per minute), and the foam remained in the washing machine is mixed with the water again and discharged under the action of the spraying water, so that the foam is removed, the washing environment is purified, and the self-cleaning of the washing machine is completed; after each program linkage is finished, the washing machine closes the drainage pump and enters the next established program.

The present technology is also effective in removing foam due to detergent overdose.

The technology for removing the foam and improving the cleaning and self-cleaning capabilities and the washing machine provided by the invention have the advantages that the pertinence and the limitation are small, the foam detection means is cancelled, the sewage discharge and foam removal operation of the system is directly carried out by utilizing the drainage process, the process is simple, the cost is low, and the efficiency is high. The technology is applied to linkage of the de-spraying and mixed-row program, the traditional washing method of washing → rinsing → dehydrating is thoroughly changed, a brand-new washing technical revolution is realized, foam is removed, the washing is easy to rinse, self-cleaning and maintenance-free, and the comfortable washing is realized; the performance of the washing machine is improved, the market share is improved, the updating of the washing machine is promoted, the energy conservation and environmental protection are enhanced, the service life of the washing machine is prolonged, and the like.

The above description is taken as an example of a drum washing machine, and the others are not listed, and the application of the technology is not limited thereto.
