Bubble resistance-reduction impeller and cleaning machine comprising same

Abstract

The invention discloses a bubble resistance-reduction impeller and a cleaning machine comprising same. The bubble resistance-reduction impeller comprises an impeller body. A first cavity and a secondcavity are formed in the impeller body. The first cavity is located above the second cavity. The second cavity is provided with a plurality of hollow pipes inserted into the first cavity. Each hollowpipe communicates with the second cavity. The first cavity is provided with a plurality of first through holes. The first through holes are coaxial with openings in the upper ends of the hollow pipes.The diameter of the first through holes is slightly greater than the outer diameter of the hollow pipes, so that gaps are reserved between the inner walls of the first through holes and the outer walls of the hollow pipes. The impeller body communicates with an air pump and a water pump. Fluid in the first cavity sprays out of the upper end of the first cavity via the gaps, and fluid in the second cavity sprays out of the upper end of the first cavity via the hollow pipes. The bubble resistance-reduction impeller can spray water and air at the same time, the resistance borne by a water columnsprayed out of the impeller in water can be reduced, the impact loss of the water column is reduced, and the cleaning capacity is improved; and meanwhile, the bubble resistance-reduction impeller hasan air-drying function.

Description

technical field [0001] The invention relates to the technical field of cleaning machines, in particular to a bubble drag-reducing pulsator and a cleaning machine including the pulsator. Background technique [0002] Chinese literature CN203646463U (application date: September 05, 2013) discloses a fruit cleaning machine including a barrel body, and the top of the barrel body is provided with an opening; wheel and a drive mechanism for driving the pulsator to rotate; the pulsator is installed at the bottom of the barrel body for rotation, and the drive mechanism is installed outside the barrel and connected with the pulsator transmission; Silicone convex particles that form a frictional fit with the fruit in the barrel. The function of the pulsator in this technical solution is the same as that of most existing pulsators used in cleaning machines. When the pulsator rotates, it drives the water in the barrel. Rotate to improve the cleaning ability of the washing machine, but ...

[0002] Chinese document CN203646463U (application date: September 05, 2013) discloses a fruit cleaning machine including a bucket body, and the top of the bucket body is provided with an opening; wheel and a drive mechanism for driving the pulsator to rotate; the pulsator is installed at the bottom of the barrel body for rotation, and the drive mechanism is installed outside the barrel and connected with the pulsator transmission; Silicone convex particles that form a frictional fit with the fruit in the barrel. The function of the pulsator in this technical solution is the same as that of most existing pulsators used in cleaning machines. When the pulsator rotates, it drives the water in the barrel. Rotate to improve the cleaning ability of the washing machine, but the existing pulsator only has the function of driving water to rotate, resulting in limited cleaning ability of the existing pulsator, its structure needs to be further optimized, and the cleaning effect needs to be further improved
