Abstract

The utility model discloses a non-metal heat transferring rapid water heater. The materials of silicon carbide, etc. with quick heat transfer and good insulating effect are used for making an insulator 4 with a plurality of small round holes in which a resistance wire 5 is penetrated. The interior and the exterior of the insulator 4 are welded and sealed by using a metallic heat transfer pipe 6 and a metallic heat transfer pipe 3, and a heater is formed. Two groups of heaters A and B with the same structure are arranged in the middle of a water storage cylinder 1 in series. A water inlet pipe 10 is arranged in the metallic heat transfer pipe in the group B, a water passing pipe 7 is connected in the metallic heat transfer pipe 6 in the group A in series from the upper end of the group B, and a water outlet pipe 9 is fixedly arranged in the water storage cylinder. The utility model has high heating speed, good energy saving effect, large safety factor and low operating cost.

Description

Nonmetal heat transfer fast water heater

One, technical field: the utility model relates to a kind of nonmetal heat transfer quick electric water heater that is used to heat hot water such as taking a shower, wash one's face or wash clothes, is a kind of household appliances.

Two, background technology: mainly be two kinds of electric heaters on the market now, a kind of is storage-type electric water heater, exists volume big, and power consumption is big, the defective that heat time heating time is long; Another kind of fast water heater, power is big, general power 6000-9000W, heat accumulation does not have a power failure and lowers the temperature immediately.

Three, summary of the invention: the purpose of this utility model provides the electric heater of a kind of energy-conservation, quick, temperature storage, safety.

Technical scheme: the materials such as carborundum that application is conducted heat, insulation effect is good, make heat transfer, the insulator of many outer circular holes, resistance wire is through in the small sircle hole of insulator, two ends seal with insulating materials, insulator has interior external application metal heat transfer pipe welded seal, puts the water cartridge heater again, forms a heater, two groups of heating element structures of A, B are identical, and polyphone is installed in the centre of water storage cylinder; Water inlet pipe is located in the interior metal heat transfer pipe of B group, crosses water pipe and is connected in series with the interior metal heat transfer pipe of A group from B group upper end, and the upper end of outlet pipe is provided with water inlet, and is fixed in the water storage cylinder.

Operation principle: after the energising, two groups of resistance wires of A, B generate heat simultaneously, conduct heat by nonmetal insulator, in being entered by water inlet pipe, running water enters outer metal tube heating after the metal tube preheating, organize to A through water pipe again and enter water storage cylinder again after inside and outside metal tube heats simultaneously, flow out from water storage cylinder upper end outlet pipe.

Compared with prior art, the utility model has following characteristics: the one, utilize that material such as nonmetal carbonization silicon is done to conduct heat, insulator, conduct heat fast, insulate, high temperature resistant, corrosion-resistant, temperature storage is effective, long service life, function little (3000-7000W), energy-conservation obvious, safety coefficient is big.
