Example one
As shown in fig. 1, a drum washing machine with filtering and self-cleaning functions comprises an outer drum 2, an inner drum 1, a filter screen 4, an air duct pipe 5, a fan 6 and a heating device.
The direction close to the inner barrel is 'inner' and the direction far away from the outer barrel is 'outer'.
As shown in fig. 1 and 2, an opening is arranged on the cylindrical surface of the outer barrel 2, and the filter screen 4 is arranged in the opening; the air duct pipe 5 is positioned outside the outer barrel, buckled on an opening of the outer barrel 2 and hermetically connected with the outer barrel 2; the fan 6 is generally installed in the air duct 5, and the fan 6 sucks air from the tub while rotating; the inner barrel 1 is arranged in the outer barrel 2, and a plurality of through holes are arranged on the surface of the inner barrel 1.
When the drum washing machine is used for dewatering, the inner barrel 1 rotates at a high speed, clothes can be separated from moisture in the clothes, water drops move to the radial outer side of the inner barrel 1 under the action of centrifugal force and move to the surface of the inner barrel 1 through the through holes, and continuously separate from the surface of the inner barrel 1 at a high speed under the action of the centrifugal force to impact the filter screen 4 and wash trapped matters on the filter screen 4.
In order to ensure that the intercepted matters of the filter screen 4 can be washed away by the water drops thrown out by the inner barrel 1, the dehydration rotating speed adopted by the invention is more than 500 r/min, and the distance between the filter screen 4 and the inner barrel 1 is less than or equal to 30 mm.
Example two
As shown in fig. 1 to 3, the difference from the first embodiment is that the second embodiment further includes a nozzle 3, the nozzle 3 is disposed in the air duct 5, and sprays water toward the filter screen 4 and flows into the outer tub 2, and the water flows to the surface of the inner tub 1 after entering the outer tub 2; in the second embodiment, the filter screen 4 can be washed during dewatering, and when other clothes washing procedures are carried out (for example, when clothes are dried), if the filter screen 4 is judged to be blocked, the intercepted objects of the filter screen 4 can be washed from outside to inside through the spray head 3; when water in the spray head 3 enters the outer barrel 2 from the filter screen 4, the inner barrel 1 rotates at a high speed, water is continuously thrown out, and the filter screen 4 can be washed.
EXAMPLE III
As shown in fig. 1 to 3, the difference from the second embodiment is that the nozzle of the third embodiment is directly inserted into the outer tub 2 to spray water into the outer tub 2, the inner tub 1 rotates at a high speed to throw out the water, and the filter screen 4 is washed. In the third embodiment, the opening of the outer barrel 2 and the filter screen 4 can only be arranged on the cylindrical surface of the outer barrel 2, but not on the end surface of the outer barrel 2; because in the third embodiment, the shower nozzle 3 can't wash filter screen 4, can only rely on the centrifugal force of interior bucket 1 high-speed rotation to get rid of the water droplet to filter screen 4 on wash, and outer bucket 2 is coaxial setting with interior bucket 1 generally, and the water droplet only can wash the face of cylinder of outer bucket 2, and can't wash the terminal surface of outer bucket 2.
As shown in fig. 1 and 4, in the second and third embodiments, the clogging of the filter screen 4 can be determined in various ways, specifically including the following.
The first method comprises the following steps: a first temperature sensor 7 is arranged at the heating device, the temperature of the gas at the heating device is measured, and if the temperature reaches a set value or the temperature change rate meets set conditions, the filter screen 4 is considered to be blocked.
And the second method comprises the following steps: an air velocity sensor is installed in the air duct pipe 5 to measure the air velocity in the air duct pipe 5, and if the air velocity drops to a certain value, it is considered that the filter screen 4 is blocked.
And the third is that: and a sensor for measuring the current and the power of the motor of the fan 6 is arranged, and if the electrical parameter of the motor of the fan 6 reaches a certain value, the filter screen 4 is considered to be blocked.
And fourthly: the second temperature sensor is arranged in the heating device to measure the temperature of the heating device, when the heating device cannot obtain enough air volume for heat dissipation, the temperature can rise, and when the temperature rises to a certain value, the filter screen 4 is considered to be blocked.
By taking a first situation as an example, the control process of the water spraying self-cleaning device is described, when a user runs a drying program, clothes fibers are generated and flow along with the air in the device in a circulating manner, and the clothes fibers flowing through the filter screen 4 are intercepted; when a user runs washing, rinsing, dewatering, barrel cleaning and other programs or a combination of programs, the rotation of the inner barrel 1 can centrifugally throw out water in clothes and hit the surface of the filter screen 4 to achieve the purpose of cleaning. When the clothes dried by a user are very seriously defibered, so that the filter screen 4 is blocked and difficult to ventilate before a certain drying program is finished, the system is inserted into a dewatering action to increase the rotating speed of the inner barrel 1, then the spray head 3 sprays water to the outer surface of the inner barrel 1, and the water is centrifugally thrown out by the rotation of the inner barrel 1 and is hit on the surface of the filter screen 4 to clean the filter screen 4. The filter screen is blocked to reduce ventilation, so that insufficient heat dissipation and too fast temperature rise of the heating device are caused, and the temperature change rate of the heating device can reflect the blocking condition of the filter screen 4. As shown in fig. 5, the cleaning method includes the steps of:
s1: collecting a signal of a first temperature sensor;
s2: processing a signal of the first temperature sensor;
s3: setting a time t, judging whether the signal variation trend of the first temperature sensor meets the set condition or not within the time t, if so, entering S4, and if not, entering S1;
s4: starting self-cleaning, forcibly running a dehydration program by the washing machine, injecting water to the surface of the inner barrel 1 by the spray head 3 when the inner barrel 1 reaches the dehydration rotating speed, and finishing self-cleaning after the time lasts for T;
s5: the washing machine continuously runs the drying program, whether the number of times that the washing machine runs S4 in one drying program reaches n times is judged, if yes, the operation is carried out in S6, and if not, the washing machine continuously runs in a circulating mode from S1 to S3; generally, n.gtoreq.2 (in the present invention, n.2);
s6: the washing machine stops operating and displays a warning code or text on the display window.
