Pump-free electric hot water circulating device

Abstract

The invention relates to a pump-free electric hot water circulating device. The device comprises a heating tank, a sealing cover, a water outlet and return pipe and a heating electrode plate and is characterized in that: the upper end of the heating electrode plate is fixedly assembled on the sealing cover of the heating tank, and the lower end of the heating electrode plate is a certain distance away from the inner bottom surface of the heating tank; the sealing cover of the heating tank is provided with the water outlet and return pipe and a pressure relieving nozzle; and the water outlet and return pipe is communicated to the bottom of the tank, and the lower end of the water outlet and return pipe is lower than the lower end of the heating electrode plate. The pump-free electric hot water circulating device has the advantages of no faults of water leakage and electric leakage, automatic backwater, simplified structure, low cost, damage resistance, no noise during working, suitability for low-power household electric heaters and high-power electric boilers and wide application range and can safely and reliably operate.

Description

technical field [0001] The invention relates to a living heating facility, in particular to a pumpless electric hot water circulator. Background technique [0002] At present, household heaters such as electric blankets and electric heaters directly use electric heating wires or electric heating tubes as heat sources, which is very unsafe. Improper use may cause fires. For this reason, the applicant has developed a "silent electrode plate heating hot water circulator" (patent No. 01113944.7), which has the advantages of safe and comfortable use, less power consumption, and low cost. Through use, it is found that there are still the following deficiencies: electrode Adopting the lower installation structure causes leakage of water and electricity; relying on the power-off device to return water results in complex structure, high cost, easy damage, and noise during operation, which is not suitable for high-power electric boilers and has a small scope of application.

[0002] At present, household heaters such as electric blankets and electric heaters directly use electric heating wires or electric heating tubes as heat sources, which is very unsafe. Improper use can easily cause fires.

For this reason, the applicant has developed a "silent electrode plate heating hot water circulator" (patent No. 01113944.7), which has the advantages of safe and comfortable use, less power consumption, and low cost. Through use, it is found that there are still the following deficiencies: electrode Using the lower installation structure, there will be leakage of water and electricity; relying on the power-off device to return water, resulting in complex structure, high cost, easy damage, and noise during operation, which is not suitable for high-power electric boilers and has a small scope of application.
