Description

Ultrasonic steam cleaner

Technical Field

The invention relates to the technical field of cleaners, in particular to an ultrasonic steam cleaner.

Background

After the range hood is used for a period of time, oil stains can be adhered to the surface of the impeller and the inner wall of the volute, the weight of the impeller is increased, the electric load is caused, the rotating speed of the impeller is influenced, the smoke exhaust and oil absorption capacity is reduced, and even the range hood cannot be normally used. Meanwhile, the inner wall of the volute is more rough due to the adhesion of oil stains, and the optimized air exhaust curved surface of the volute is influenced, so that the noise of the range hood is increased. In the cooking process, the oleic acid glyceride and the unsaturated oil in the edible oil are oxidized and polymerized at a high temperature for a long time to form a paint-like polymer with strong viscosity and toughness; part of the edible oil is gasified, condensed and even carbonized and then attached to the surface of the solid to form film-type dirt with strong stiffness and toughness; tiny dust and fine particles floating in the living environment can also adhere to and deposit on the oil dirt, further increasing the difficulty of removal.

The hot dry cleaning method mainly utilizes a heater to heat and remove oil from the volute, but the existing design only installs heaters such as an electric heating tube, an electric heating wire, an electric heating belt, a PTC and the like at the local parts of a fan and the outer wall, and the inner wall of the volute is easy to generate the problems of uneven heating, poor thermal efficiency, insufficient heat conduction force, large energy consumption and the like. The fan has the advantages that the fan and the outer wall are provided with a plurality of additives, the appearance is influenced, the fan blades and the outer wall are locally heated, dead angles are easily left on the inner wall, oil stains on the surface of the impeller and the inner wall of the volute are not thoroughly removed, and if the heating temperature is too high, the accumulated oil stains are easily combusted, so that certain potential safety hazards exist.
