Description
Technical Field
The invention belongs to the technical field of household appliances, and particularly relates to a pulsator washing machine and a control method thereof.
Background
In the washing process of the pulsator washing machine, the rotation of the pulsator stirs clothes to turn over in water and the clothes respectively rub and collide with the pulsator and the inner barrel wall, so that a good washing effect is achieved. The existing pulsator washing machine on the market realizes the stirring and overturning of clothes through the rotation of the pulsator or the common rotation of the pulsator and the inner barrel, but in the actual washing process, because the height of the pulsator is limited, the clothes can only rotate at the bottom of the barrel under the rotating action of the pulsator, the rotation of the inner barrel is periodic positive rotation and reverse rotation, particularly in the washing process of high water level, the clothes can not be overturned sufficiently, the washing force is insufficient, the washing effect is poor, and poor experience is brought to users.
In order to solve the problems, the prior art adopts a power impeller washing machine to change the impeller structure of the washing machine in order to increase the turning force on clothes. However, in the washing process, the impeller has large rotating force, and the abrasion to the clothes is increased in the low water level washing process. The inner part of the sky-wash washing machine is provided with a spraying device which has the function of increasing the mixing degree of detergent, water and clothes, but the problem that the clothes cannot be fully overturned in the washing process cannot be solved.
In order to solve the problems, the prior art adopts a scheme that an air cavity or an air passage is arranged at the bottom of the impeller, and the air cavity or the air passage is hermetically communicated with the impeller, so that air enters the cavity of the impeller through the air cavity or the air passage and enters the inner barrel through holes on the surface of the impeller, the overturning degree of clothes accumulated at the bottom of the inner barrel is increased, the washing effect is improved, and meanwhile, the abrasion to clothes is reduced. However, the air cavity and the air passage are arranged while considering the sealing with the rotary shaft of the impeller and the volume of the motor structure, thereby invisibly increasing the process difficulty and leading the compact barrel bottom space to be more crowded.
In view of the above, the present invention is particularly proposed.

Example 5
In this embodiment, a control method of a pulsator washing machine as described in embodiment 1 or 2 is provided, in order to enhance the structural strength of the bottom of the tub, the distance between the air outlets is relatively large, so that when the inner tub rotates to the water discharge port and passes through the air inlet, the washing machine controls the air supply device to be activated, so that air enters the pulsator cavity through the air inlet and enters the inner tub through the air outlet.
In the embodiment, the washing machine controls the air supply device to be opened all the time or intermittently in the washing and rinsing processes, and simultaneously closes the drain valve; closing the air supply device and the drain valve simultaneously in the dehydration process; and closing the air supply device and opening the drain valve in the water discharging process. Because the gas delivered by the gas delivery device diffuses between the outer barrel and the inner barrel, the method provided by the embodiment sets the gas delivery device to work at a certain frequency, starts gas delivery when the inner barrel rotates to the position where the gas inlet corresponds to the water outlet, and stops gas delivery when the gas inlet is staggered with the water outlet.
In this embodiment, when the inner tub is switched to rotate in the forward and reverse directions, the washing machine controls the inner tub to rotate until the air inlet corresponds to the water outlet, and the air supply device is started to supply air into the inner tub through the air inlet.
In the embodiment, because the inner barrel of the pulsator washing machine rotates forwards and backwards in the washing process, the inner barrel and the outer barrel are temporarily and relatively static in the forward rotation and reverse rotation interval, the inner barrel can be controlled to rotate to the position where the air inlet corresponds to the water outlet, and air supply is started at the moment, so that air is not influenced by transverse water flow and rotation of the inner barrel and is led into the inner barrel more intensively.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
