Heat absorption type fireproof ring of water heater heated by using residual heat of household gas cooker

Abstract

The invention discloses a heat absorption type fireproof ring of a water heater heated by using residual heat of a household gas cooker, comprising a fireproof ring, heat absorption sheets and a spiral pipe, wherein the outer wall of the fireproof ring is tightly connected with the spiral pipe formed by coiling one metal pipe; and the inner wall of the fireproof ring is uniformly distributed with the heat absorption sheets in a radiation shape. The main effect of the heat absorption sheets is to enlarge a heat absorption surface and the heat absorption sheets also play a role in supporting a pan. The fireproof ring also plays an efficient heat conduction role except the fireproof effect, so that the heat absorbed in a cooking process is conducted to the spiral pipe to heat the water in a heating pipe. Two ends of the spiral pipe are connected with a heat-preservation water storage bucket at two ends and above the spiral pipe through two pipes. The heat absorption type fireproof ring disclosed by the invention has the advantages of simple structure, easiness for implementation, environmental friendliness and energy saving, and can increase the residual heat increasing amount under the condition of not influencing cooking.

Description

technical field [0001] The present invention relates to waste heat water heaters, and more particularly relates to a heat-absorbing flame-insulating ring for household gas stove waste heat heating water heaters. [0002] Background technique [0003] With the continuous improvement of people's living standards, water heaters have been widely used not only in cities but also in rural areas. Today's water heaters mainly include electric water heaters, natural gas water heaters, and solar water heaters. The former two consume a lot of electric energy or natural gas, while the latter uses clean solar energy, but it cannot heat water on cloudy days, winter, and nights. However, the utilization rate of heat in people's cooking stoves is very low, and more heat energy goes to the air through the outside of the pot. A kind of equipment of design remains to be explored for this reason, so that can make full use of the superfluous thermal energy of outside the pot. [0004] Conte...

Problems solved by technology

Today's water heaters mainly include electric water heaters, natural gas water heaters, and solar water heaters. The former two consume a lot of electricity or natural gas, while the latter uses clean solar energy, but it cannot heat water in cloudy days, winter, and nights.

However, the stoves that people cook now have a very low heat utilization rate, and more heat energy goes to the air through the outside of the pot.
