Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] see figure 1 , the housing 1 of the anti-shock type thermoelectric water heater is provided with an insulated water inlet pipe 5 and an outlet pipe 6, and a heating chamber is arranged between the water inlet pipe 5 and the water outlet pipe 6, and the heating chamber can be arranged in the housing 1. At any position between the water inlet pipe 5 and the water outlet pipe 6, the heating chamber is an insulated pipe-type heating body 2, and the electric heating wire 3 is directly exposed in the pipe-type heating body 2, and is directly connected with the electric heating element flowing through it. The water on the surface of the wire 3 performs heat exchange. Among them, the relationship between the length and radius of the water inlet pipe 5 and the water outlet pipe 6 should satisfy: L>53r 2 . The water inlet pipe 5 and the water outlet pip...

Abstract

The invention relates to electric shock preventing type pyroelectricity water heater. It includes water inlet pipe, outlet pipe, and electric heater. The water inlet and outlet pipes are insulating. There is one heating chamber between them. And the heating chamber is pipeline type heating body. The electric heater is electric heating wire. The relationship of the length and semidiameter of the inlet and outlet pipes must satisfy that the former is 53 times bigger than the latter's square. And they are respectively connected to ports. And the pipeline connector is set between them. It has the advantages of simple structure, low cost, high heating efficiency, and safe.

Description

technical field [0001] The invention relates to an electric shock-proof instant thermoelectric water heater. Background technique [0002] Disclosed in the Chinese patent ZL01139193.6 is a kind of instantaneous heating type high-efficiency electric water heater. It includes: water inlet valve, water pressure switch, integral internal water and electric heating pipe and temperature control device, etc. After the cold water pipe passes through the water inlet valve and water pressure switch, it is directly connected with the integral internal water and electric heating pipe. Since the outer wall of the integral internal water electric heating pipe contains electric heating materials, the required hot water can flow out of the pipe after the electricity is turned on. Since the instant electric water heater of this structure is not equipped with a leakage protection device, it is easy to break down the circuit, which makes the heated water carry a relatively large current, caus...
