After flocculation treatment of sewage, the dirt in the sewage becomes floccule and moisture leaving, resulting in flocculation in the flocculation barrel. If the floc adheres to the side wall of the flocculation bucket, it will cause secondary pollution to the subsequent flocculated water. The long-term retention of the floc will cause a large amount of bacteria to be generated in the flocculation bucket. The present invention provides a self-cleaning control method for the flocculation bucket of the washing machine. When the washing machine judges that the flocculation bucket needs to be cleaned, the preset washing procedure of the washing machine is started, and the flocculation bucket can be realized. Self-cleaning to remove the floc retained in the flocculation bucket.

The existing method for cleaning the flocculation barrel adopts a flushing flocculation barrel, or a method of storing water in the flocculation barrel and stirring the water in the barrel, but due to the large viscosity of the floc, the strength of the stirring and the water flow cannot be completely removed. The invention adopts a chemical agent to clean the flocculation barrel, and the chemical agent can be a cleaning agent which is one or more combination of an acidic cleaning agent, an alkaline cleaning agent, a bactericide and a disinfectant, and a mixed cleaning agent is introduced into the flocculation barrel. And the water cleaning liquid, stir the cleaning liquid in the flocculation barrel, and after the stirring, the cleaning liquid is immersed in the flocculation barrel for a predetermined time and then discharged, so that the floc inside the flocculation barrel and the floc attached to the side wall of the flocculation barrel are in the cleaning agent. Under the action, it is discharged with the cleaning liquid, which solves the problem that the flocculation barrel cannot be thoroughly cleaned by rinsing with water or stirring. Moreover, the problem that the water flow flushing hardly covers the complicated structure of the entire barrel wall is solved.

Cleaning the flocculation tank with a cleaning solution mixed with chemicals and water may cause a small amount of chemical-containing cleaning agent to remain in the flocculation tank, which will affect the flocculation effect, and the residual chemical mixed into the washing water will affect the laundry effect or Clothing causes damage. Therefore, in the cleaning process, after the cleaning liquid is discharged from the flocculation tank, the clean water is introduced into the chamber of the detergent box and the flocculation tank into which the cleaning agent has been applied, and is stirred and discharged.

detailed description

The embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is not intended to limit the scope of the invention.

The self-cleaning of the flocculation bucket of the existing washing machine is mostly by flushing and storing the flocculation bucket by using the rinse water before the washing and washing of the washing machine is finished, and assisting the stirring after the water storage process, and separately flushing The water and the water storage are discharged, so that the flocs remaining in the flocculation bucket are cleaned by the flushing water and the water storage, and are discharged to achieve self-cleaning of the flocs in the flocculation bucket. The self-cleaning water used in the flocculation bucket in the above process comes from the washing water of the laundry, that is, the self-cleaning of the flocculation bucket must be carried out after the laundry, and if the washing machine does not carry out the laundry, the self-cleaning of the flocculation bucket cannot be performed, the pair of cleaning flocculation buckets Caused certain limitations.

To solve the problem, the flocculation bucket self-cleaning control method of the washing machine provided by the present invention is a preset program on the main controller of the washing machine, and is independent of the washing program. The washing machine can also perform self-cleaning of the flocculation bucket without performing washing, and the user can Start the flocculation bucket self-cleaning program to control the washing machine to clean the flocculation bucket separately, and the cleaning flocculation bucket is no longer limited by the laundry. The main controller of the washing machine calculates whether the flocculation bucket needs to be cleaned by the time and/or the number of water treatment cycles. When the calculation result indicates that the flocculation bucket needs to be cleaned, the washing machine notifies the user through panel display, sound and light alarm, etc., and can realize the flocculation bucket. Timely cleaning, avoiding the long-term retention of floc in the flocculation bucket to breed a large number of bacteria, which is conducive to washing clothes.

Secondly, the above method uses a water flow to rinse the flocculation barrel wall, and uses a stirring mechanism in the flocculation barrel to generate a stirring water flow to wash the barrel wall of the flocculation barrel cleaning method. Since the flocculant is added with a high molecular polymer, the flocculation is adhered. The property is very strong, and the floc is easily broken by the water flow, and is more likely to adhere to the inner wall of the flocculation bucket, so that the stirring water flow intensity is not too large, and the flushing force of the water flow cannot completely remove the flocculation problem. At the same time, if the flocculation bucket is flushed by the influent water flow, the influent water flow needs to cover the entire bucket wall, but in fact, the water flow flushing is difficult to cover the complicated structure of the entire bucket wall, and if the nozzle flushing is used, the cable debris may block the hidden danger of the filter screen. The water intake is not smooth, which affects the normal flocculation.

In order to solve the above problems, the self-cleaning control method for the flocculation bucket of the washing machine provided by the present invention uses a chemical agent to clean the flocculation bucket, and uses a special chemical agent for the floc property to clean the flocculation bucket, and the chemical agent can be an acidic cleaning agent or an alkaline cleaning agent. a combination of one or more of a bactericide, a disinfectant. When the washing machine informs the user that the flocculation bucket needs to be cleaned through the panel display, sound and light alarm, etc., the user puts the chemical agent into the detergent delivery box. Medium, then start the flocculation bucket self-cleaning process, and the washing machine performs self-cleaning of the flocculation bucket.

As shown in FIG. 1 , the self-cleaning control method of the flocculation bucket of the washing machine provided by the present invention has the following steps:

Step S101, determining whether the flocculation bucket needs to be cleaned;

Step S103, starting a washing program preset by the washing machine;

Step S106, pumping the washing liquid of the washing tub into the flocculation bucket,

Step S109, discharging the cleaning liquid;

In the self-cleaning process described above, after the washing program preset by the washing machine is started, the washing machine executes step S104 to inject a predetermined amount of tap water into the washing tub through the chamber A containing the chemical agent, that is, the cleaning agent. The amount of water is the amount of water when the flocculation bucket reaches the washing water level. At this time, step S105 is performed to stop the water inflow. In the above process, the cleaning agent is flushed into the washing tub with the water, and the cleaning agent and the water are mixed in the washing tub to form a cleaning flocculation bucket. Cleaning solution. Then, in step S106, the water pump pumps the cleaning liquid from the washing tub into the flocculation bucket. In order to fully dissolve and mix the cleaning agent and the water, before the step S106 is performed, the process of mixing the cleaning agent and the water in the washing tub into the cleaning liquid is heated, and the heating also improves the cleaning effect of the cleaning agent on the flocculation barrel.

Steps S106 to S108 are the flocculation barrel cleaning process, and the highly adherent floc attached to the inner wall of the flocculation barrel is peeled off from the inner wall into the cleaning liquid under the action of the cleaning agent, and the stirring process includes the T1 duration. The soaking process with the T2 duration allows the floc attached to the inner wall of the flocculation bucket to fall sufficiently into the cleaning liquid.

In the prior art cleaning process, since the floc is easily broken by the water flow and more adheres to the inner wall of the flocculation bucket, the stirring force cannot be too large, and the flushing force of the water flow cannot completely remove the flocculation problem. The invention uses the chemical agent to clean the flocculation bucket, so the stirring force, the rotation degree and the forward and reverse frequency in the cleaning process can be not required, and the inventor has repeatedly tested and found that the stirring speed is increased and the positive and negative rotation is increased. Frequency It is beneficial to improve the cleaning effect of the flocculation bucket.
