Stoves that use waste heat to generate steam

Abstract

The invention relates to a cooking range generating steam by using waste heat. The cooking range a furnace body, a furnace head and a water tank, wherein the furnace body is combined by an inner furnace wall and an outer furnace wall; a hollow region surrounded by the inner furnace wall is a hearth; a plurality of tubular fire bars are uniformly arranged below the hearth at intervals in the furnace body; the furnace head comprises an outer furnace ring, an inner furnace ring and a pot body supporting ring; the lower end of the inner furnace ring is connected to the inner furnace wall; the lower end of the pot body supporting ring is connected to the outer furnace wall; a cavity among the inner wall furnace, the outer wall furnace and the furnace head is a heating cavity; a coil surrounding the hearth is arranged in the heating cavity; a steam pipe communicating with the top of the heating cavity is arranged in the upper part of the water tank; a water outlet pipe communicating with the bottom of the heating cavity is arranged in the lower part of the water tank; a gas outlet pipe is arranged on the top of the water tank; a water inlet is formed between the steam pipe and the water outlet pipe on the water tank; and a float ball water inlet valve is arranged on the water inlet. The cooking range provided by the invention realizes efficient recovery of smoke heat and automatic control of water inflow in a stove using process.

Description

Technical field [0001] The present invention relates to kitchen appliances, in particular to a stove that uses waste heat to generate steam. Background technique [0002] The heating principle of traditional stoves is to heat the bottom of the pot by burning fuel directly in the atmosphere. Although this heating method can also achieve the purpose of heating the cooker, the heat generated by the flame and the high-temperature flue gas will overflow from the gap between the bottom of the pot and the stove, and the heat is not fully utilized, which causes a waste of energy. In the existing market, some improvements have been made to stoves, which can utilize the waste heat of the flue gas from the stoves to produce hot water or steam, but its heat transfer efficiency is low, and the utilization rate of waste heat is not high, resulting in its steam generation speed. The effect is not obvious; and the existing steam energy-saving stoves need to be manually filled with water regular...

Problems solved by technology

Although such a heating method can also achieve the purpose of heating the cooker, the heat generated by the flame and the high-temperature flue gas will overflow from the gap between the bottom of the pot and the stove, and the heat will not be fully utilized, resulting in a waste of energy.

In the existing market, some stoves have been improved, and the waste heat of the flue gas of the stove can be used to generate hot water or steam, etc., but the heat transfer efficiency is low, and the utilization rate of waste heat is not high, resulting in the speed of steam generation. Slow, the effect is not obvious; and the existing steam energy-saving stoves need to manually add water regularly, otherwise it is easy to appear the phenomenon of dry burning, resulting in certain restrictions on the promotion of such products
