TL;DR: In this article, a rotatable inner drum and axial pipeline are used to spray washing liquid to the clothes in the inner drum of a washing machine to take away stain and reduce splashing and huge increase of washing foam.
Abstract: The invention discloses a centrifugal washing method and a washing machine. The method includes: enabling clothes in a rotatable inner drum to rotate along with the inner drum and closely attach to the inner wall of the inner drum under the action of centrifugal force, and enabling washing liquid to be sprayed to the clothes continuously from an axial pipeline at the inner center of the inner drum and to penetrate the clothes under the action of the centrifugal force to take away stain, so that the clothes are washed and wear of the clothes is reduced, wherein the liquid level of the washing liquid is constantly lower than the lowest position of the inner drum during washing. The washing machine using the method avoids splashing and huge increase of washing foam caused by the fact that the inner drum in high-speed rotation hits the washing liquid. Meanwhile, water resource is saved, resistance of the washing liquid to the inner drum in high-speed rotation is weakened, power consumption is reduced, and washing is cleaner and more even.

TL;DR: In this paper, the authors described a permanent magnet type air pump, which relates to low-pressure air compression equipment and belongs to a double-cylinder or double-membrane single-phase alternating-current full wave air pump.
Abstract: The invention discloses a permanent magnet type air pump, relates to low-pressure air compression equipment and belongs to a double-cylinder or double-membrane single-phase alternating-current full wave air pump. Driving power of the permanent magnet type air pump is produced through combined action of a magnetic field of a permanent magnet and an electromagnetic field. The two sides of a driving shaft 6 of the permanent magnet type air pump are provided with two permanent magnets 10 correspondingly, the middle of the driving shaft 6 is provided with a coil 4 and a hollow iron core 5 which are fixed to a pump body 3, and the driving shaft 6 can freely move in the hollow iron core 5 in the axial direction. When the coil 4 is connected to a single-phase alternating-current power source, an alternating magnetic pole is produced on the side, facing the permanent magnet, of the iron core 5, and the sides, facing the iron core 5, of magnetic poles of the two magnets on the driving shaft are the same in polarity (N pole or S pole). Due to the fact that the driving shaft 6 does straight reciprocating motion under the effect of attraction and repulsion of the electromagnetic field and the permanent magnet field, two pistons or membranes are driven to achieve air pump suction and compression stroke. Due to the fact that only attraction of the electromagnetic field is used as driving force of the electromagnetic type air pump, the permanent magnet type air pump has the good energy saving effect.
