Heating body of electric heating tap

Abstract

The invention discloses a heating body of an electric heating tap. The heating body comprises a water inlet channel, a water outlet channel, a water route control system, an upper cover, a water-and-electrical cabin barrel, a lower cover, a hydraulic pressure switch flow channel and an electricity-isolated heat-conducted heating sheet. The upper cover and the lower cover are matched with the water-and-electrical cabin barrel and form a water-electricity isolated closed heating cabin. A cold water inlet channel communicated with the water inlet channel and the hydraulic pressure switch flow channel are disposed in the water-and-electrical cabin barrel, a plurality of isolating blocks are fixedly disposed on the periphery of the water-and-electrical cabin barrel circularly, and the isolating blocks separate the water-and-electrical cabin barrel and the cold water inlet channel or the hydraulic pressure switch flow channel into a plurality of twisted and wounded irreversible water channels. One end of the isolating block between adjacent water channels is a closed structure, and the other end of the isolating block is a hollow jack structure. One end of the hollow jack is communicated with the electricity-isolated heat-conducted heating sheet of an external power supply, and the water route control system controls water to flow in and out of the water channels. The heating body of the electric heating tap has the advantages that electricity-and-heat conversion efficiency is high, safety is good, long time heating without water is bearable, and maintenance is simple and convenient.

Description

Technical field [0001] The invention relates to a heating body of an electric hot water faucet. Background technique [0002] Electric hot water faucet is a perfect combination of water heater and faucet. It is favored by users because of its advantages of saving water and electricity, ready to use, and convenient installation. The heating element is the key part and core technology of the electric faucet, which directly determines the safety, heating effect, thermal efficiency and life of the electric faucet. At present, the heating element of the electric heating faucet on the market is a spiral copper or stainless steel electric heating tube or a nickel-chromium alloy bare-wire heating element using the principle of the water resistance attenuation method. The spiral copper or stainless steel electric heating tube is made of iron-chromium-aluminum heating wire on the central axis of the copper or stainless steel tube. The peripheral wall is insulated with crystalline magnesiu...

AI Technical Summary

Problems solved by technology

If the channel design is unreasonable (the attenuation of water resistance is not in place), the grounding is not in place, or there is a problem with the wiring in the user's home, it will endanger the life of the user at any time

Direct heating of bare wire in water is likely to cause blisters and burn the heating wire, resulting in machine scrapping and casualty accidents, and the surface of bare wire is prone to scaling and oxidation reactions, which reduces the thermal efficiency, heating effect, safety and life of bare wire

Whether it is a spiral copper or stainless steel electric heating tube or a nickel-chromium alloy bare wire heating element that uses the principle of water resistance attenuation method, it cannot be dry-burned. The heating element is not completely covered by water, and it is easy to dry-burn. An explosion will endanger life safety and cause the machine to be scrapped

Whether it is a spiral copper or stainless steel electric heating tube or a nickel-chromium alloy bare wire heating element using the principle of water resistance attenuation method, the heating element is placed in the whole cylinder of water for heating, and the water will flow out without being fully heated or be cooled by cold water. When the water flow rate is increased, the water flowing out will not be hot. The heating method is an instantaneous linear heating and the heating is uneven.

[0003] To sum up, the electric faucet heating element in the prior art has low safety, short life, high consumption, low thermal efficiency, poor heating effect, dry burning, insufficient instantaneous linear heating, uneven heating, and easy scaling. defect
