More safe water heater

Abstract

The invention relates to a more safe water heater which consists of an electric heat source body or other heat source bodies, a heating container adopting a high volatile substance as a heat medium and containing a water heat exchanger and a safety device mounted at the highest position of the heating container and communicated with the interior of the heating container. The more safe water heater utilizes a safety valve containing a pressure switch and a condensation recovery device which are communicated with the interior of the heating container and mounted on the heating container of the water heater, thereby leading the high volatile substance which is taken as the heat medium for heating water in the water heat exchanger, not only keeping the advantage of improving the heat efficiency, but also eliminating the major potential safety problem of extraordinary pressure.

Description

Technical field [0001] The present invention is related to heating equipment using highly volatile substances as heat medium, in particular to a safer water heater. Background technique [0002] At present, the known conventional water heaters generally use a heat source body to directly heat water, and the technology of the safety problem has been solved. Now there is a kind of high volatile substances, such as benzene, ethers, alcohols or their mixtures, as the heat medium of the water heater. Using this highly volatile substance as a heat medium to make a water heater can indeed significantly improve the thermal efficiency. Although the pressure in the chamber of the water heater is lower than normal pressure, due to the presence of a water heat exchanger, the water heat exchanger has quality problems. Or when water seeps out of the water heat exchanger after long-term use, this type of water heater will have a major safety hazard during operation, that is, it cannot ens...

Problems solved by technology

Using this highly volatile substance as a heat medium to make a water heater can indeed significantly improve thermal efficiency. Although the pressure in the chamber of this type of water heater is lower than normal pressure, because there is a water heat exchanger in it, there are quality problems in the water heat exchanger. Or when water leaks out of the water heat exchanger after long-term use, this kind of water heater will have a major safety hazard during operation, that is, it cannot ensure that the water heater chamber is always at normal pressure or below normal pressure
