Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Example one
The embodiment provides a rinsing control method of a washing machine, which is suitable for the washing machine with a fixed-frequency motor. Specifically, referring to fig. 1, the rinsing control method of the washing machine specifically includes the following steps:
s101, setting intermittent dehydration processes before and after a spray rinsing process in a rinsing program of the washing machine.
That is, when the motor of the washing machine is a constant frequency motor, the present embodiment is provided with an intermittent dehydration process in the rinsing process. Specifically, the intermittent spinning course is provided before and after a spray rinsing course in a rinsing course of the washing machine. The above-described intermittent dehydration process is performed in which the tub is operated at a preset spin-stop ratio, which is known and determined according to a number of repeated tests. And the intermittent dehydration process is performed for 10s to 60s, preferably 30s.
In the rinsing program of this embodiment, a continuous dehydration process, an inertial dehydration process, and a braking process are sequentially provided after the intermittent dehydration process. The intermittent dehydration process, the continuous dehydration process, the inertial dehydration process and the braking process together form the dehydration process in the rinsing procedure. That is, in the present embodiment, the dehydration process is provided before and after the spray rinsing process.
The continuous dehydration process means that the washing tub is continuously rotated at a second preset rotation speed for a second preset time, wherein the second preset rotation speed and the second preset time are known and determined according to a plurality of repeated tests. Preferably, the second preset time of the continuous dehydration process before the spray rinsing process is 40s, and the second preset time of the continuous dehydration process after the spray rinsing process is 1 minute.
In this embodiment, the spray rinsing process means that the washing tub stops 5s after rotating for every 1s, and stops spraying for 3s after spraying for every 3s, and circulates for 60s according to the above process. The rotating and stopping ratio of the washing barrel, the time of spraying water in, the time of stopping spraying and the cycle time in the spraying rinsing process can be adjusted.
S102, barrel collision judgment is carried out in the dehydration process, and whether the barrel collision occurs after the spray rinsing process is judged.
That is, during the dehydration process, the existence of barrel collision is detected in real time (the barrel collision is determined as the prior art, and the details are not described here). When the barrel collision phenomenon occurs, whether the barrel collision occurs after the spray rinsing process, before the spray rinsing process or in the spray rinsing process is judged.
S103, when the barrel collision happens after the spray rinsing process, the unbalance correction is carried out on the inlet water, and the dehydration process after the spray rinsing process is executed again from the intermittent dehydration process after the spray rinsing process.
When the tub collision occurs after the spray rinsing process, the washing machine feeds water into the washing tub and performs unbalance correction (how to perform unbalance correction is the prior art, and therefore, the description is omitted), and after the unbalance correction, the washing machine starts from the intermittent dewatering process after the spray rinsing process and performs the dewatering process after the spray rinsing process again. Note that, in the continuous dehydration process after the spray rinsing process, the time of the continuous dehydration process is preferably 3 minutes.
It should be noted that, when the tub collision occurs before the spray rinsing process, the washing machine performs unbalance correction on the water supplied into the washing tub, and after the unbalance correction, starts the intermittent dehydration process before the spray rinsing process, and re-executes the dehydration process before the spray rinsing process.
When the tub is collided in the spray rinsing process, the washing machine suspends the current spray rinsing process and continues to execute the current spray rinsing process after suspending for a first preset time. After the first preset time of pause, the clothes are given sufficient water absorption time, and the possibility of barrel collision when the current spray rinsing process is operated again is greatly reduced. Wherein the first predetermined time is known and is determined from a plurality of repeated experiments.
In the embodiment, through the step S102, the problem that the barrel is frequently hit when the large clothes or jeans are rinsed can be avoided, the rinsing efficiency is improved, and water resources are saved.
The invention also provides a washing machine, and by adopting the rinsing control method of the washing machine, the problem that the washing machine frequently collides a barrel can be avoided, the service life of the washing machine is prolonged, the user experience is improved, and water resources are saved.
Example two

Specifically, referring to fig. 2, the rinsing control method of the washing machine specifically includes the following steps:
s201, setting low-speed dehydration processes before and after a spray rinsing process in a rinsing program of the washing machine.
That is, when the motor of the washing machine is a variable frequency motor, the present embodiment is provided with a low-speed dehydration process in the rinsing process. The low-speed spinning course is provided before and after a spray rinsing course in a rinsing course of the washing machine. The washing barrel continuously rotates in the low-speed dehydration process, and the rotating speed of the washing barrel is lower than a first preset rotating speed.
In the rinsing program of this embodiment, a high-speed dewatering process, an inertia dewatering process, and a braking process are sequentially performed after the low-speed dewatering process. The low-speed dehydration process, the high-speed dehydration process, the inertial dehydration process and the braking process together form the dehydration process in the rinsing program. That is, in the present embodiment, the above-described dehydration process is provided before and after the spray rinsing process.
The high-speed dehydration process means that the washing tub continuously rotates for a designated time at a predetermined rotation speed, and the rotation speed of the washing tub is greater than a first preset rotation speed. Wherein the first predetermined speed, the predetermined speed, and the designated time are known and determined from a plurality of repeated tests.
The spray rinsing process in this embodiment means that the washing tub rotates at a spray rotation speed, and the spray is stopped for 3 seconds after the water is sprayed for 3 seconds, and the cycle is performed for 60 seconds according to the above process. The spraying speed of the washing barrel, the time for spraying water, the time for stopping spraying and the cycle time in the spraying rinsing process can be adjusted.
Preferably, the low-speed dehydration process is followed by a high-speed dehydration process, an inertial dehydration process and a braking process in sequence.
S202, barrel collision judgment is carried out in the dewatering process, and whether the barrel collision occurs after the spray rinsing process is judged.
S203, when the barrel collision happens after the spray rinsing process, the water inflow is subjected to unbalance correction, and the low-speed dehydration process after the spray rinsing process is started, and the dehydration process after the spray rinsing process is executed again.
When the tub collision occurs after the spray rinsing process, the washing machine feeds water into the washing tub and performs unbalance correction (how to perform unbalance correction is the prior art, and therefore the description is omitted), and after the unbalance correction, the washing machine starts from the low-speed dewatering process after the spray rinsing process and performs the dewatering process after the spray rinsing process again.
It should be noted that, when the tub collision occurs before the spray rinsing process, the washing machine performs unbalance correction on the water entering the washing tub, and after the unbalance correction, the washing machine starts from the low-speed dewatering process before the spray rinsing process and re-executes the dewatering process before the spray rinsing process.
When the tub is collided in the spray rinsing process, the washing machine suspends the current spray rinsing process and continues to execute the current spray rinsing process after the suspension for a first preset time.
The embodiment also provides a washing machine, and by adopting the rinsing control method of the washing machine, the problem that the washing machine frequently collides the barrel can be avoided, the service life of the washing machine is prolonged, the user experience is improved, and the water resource is saved.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments.
