A self-cleaning smart home electric water heater

Abstract

The invention discloses a self-cleaning type intelligent household electric water heater, which comprises a casing and an inner container arranged in the casing. The inner wall of the inner container is symmetrically fixedly connected with a heating rod and a magnesium rod, and the inner container is fixed relative to the inner wall. A cross bar is connected, the side wall of the cross bar is covered with a ring, and the inner wall of the liner is fixedly connected with the side wall of the ring through a memory spring, the side wall of the ring is fixedly connected with a scraper ring, and the scraper The side wall of the ring is provided with a through hole matched with the heating rod and the magnesium rod. In the present invention, the memory spring is heated and elongated to push the circular ring to move on the cross bar, so that the scraper ring and the inner wall of the through hole can remove the scale on the inner tank, heating rod and magnesium rod, effectively reducing the probability of scale accumulation inside the water heater , Increase the service life of each component inside the water heater.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a self-cleaning electric water heater for smart home. Background technique [0002] Smart home is based on the residence as a platform. It manages residential facilities and family schedules through a variety of advanced technologies, improves home safety and comfort, and realizes an environmentally friendly and energy-saving living environment. Electric water heaters are more environmentally friendly and efficient in heating cold water. equipment, making it more widely used in smart homes. [0003] Because the water contains a lot of mineral metals, scales will be formed when the water is heated, and these scales will adhere to the surface of the heating rod and the inner tank, which will reduce the heating efficiency of the heating rod to the water in the water heater after the water heater is used for a long time It slows down and reduces the heat preservation effect of th...

Problems solved by technology

[0003] Because the water contains a lot of mineral metals, scales will be formed when the water is heated, and these scales will adhere to the surface of the heating rod and the inner tank. After the water heater is used for a long time, the efficiency of the heating rod to heat the water in the water heater will be reduced. It slows down and reduces the heat preservation effect of the inner tank on hot water, and increases the power resource loss. In addition, after a long time of use, the surface of the magnesium rod is easily attached by dirt, which reduces the protective effect of the magnesium rod and speeds up the heating. Accumulation of limescale on sticks
