Technical Field

The utility model relates to an energy-conserving burner device, especially a thermal efficiency is high, and the heating is even, usable waste heat, the novel energy-conserving gas kitchen range that has waste heat recovery function that the noise is little.

Background

At present, most of flame of commercial stoves transfers heat to the bottom of a pot through air convection, the flame is only instantly contacted with the bottom of the pot, most of heat is dissipated in the air, the heat loss is serious, and the heat efficiency is low. Meanwhile, the gas flame is concentrated at the bottom of the pan, the time for heating the pan uniformly is long, and the problem that the temperature of the bottom of the pan is higher than the temperature of the periphery of the bottom of the pan cannot be solved, so that the pan is easily burnt.

Commercial stoves include commercial energy-saving stoves and commonly adopt bottom air supply waste gas to go up the mode of arranging, and the bottom of a boiler must leave the clearance so that waste gas discharges between the cooking utensils, therefore a large amount of waste heat runs off along with waste gas. Exhaust gas that upwards discharges not only pollutes the kitchen environment, and high temperature waste gas upwards diffuses moreover and increases kitchen limit temperature, and user experience is poor.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a novel energy-saving gas cooking range with the functions of heat recovery, high heat efficiency, even heating, utilization of waste heat and low noise.

The novel energy-saving gas cooking range with the waste heat recovery function comprises a furnace basin, wherein a burner is arranged in the middle of the inside of the furnace basin, a fire gathering ring is arranged on the circumference of the top of the burner, a conical energy gathering ring support is arranged at the top of the fire gathering ring, a hollow energy gathering isolation layer is arranged inside the conical energy gathering ring support, a conical energy gathering ring which is matched with the conical energy gathering ring support and is provided with a plurality of energy gathering bulges is arranged at the top of the conical energy gathering ring support, and a circle of waste gas discharge holes are further formed in the circumference of the conical energy gathering ring; the lower part of the burner and the inside of the furnace basin are sequentially provided with a gas mixing cavity, a long fire tube and a main fire breaking air valve from top to bottom, the bottom of the main fire breaking air valve is connected with an air inlet pipeline, the lower part of the burner and the inside of the furnace basin are also provided with a waste gas cavity which is arranged side by side with the gas mixing cavity and is not communicated with each other, and the waste gas cavity is communicated with the air inlet pipeline and a waste gas outlet arranged on the side surface of the bottom of the furnace basin. The edge of the furnace basin 1 is provided with a flanging which is used for being tightly matched with the bottom of the pot.

According to the novel energy-saving gas cooking range with the waste heat recovery function, after main fire gas and air enter through the air inlet pipeline, the main fire gas and the air are fully premixed in the gas mixing cavity and are upwards sprayed through the burner, and high-temperature blue flame is formed and sprayed to the bottom of a pot and is scattered along the bottom of the pot; one part of heat is heated to the bottom of the pot, and the other part of heat is subjected to energy accumulation and upward reflection through the conical energy accumulation ring to realize secondary radiation heating; flue gas enters the furnace basin through a waste gas discharge hole on the conical energy-gathering ring, downwards flows along the inner wall of the furnace basin, and enters a waste gas cavity through the bottom of the furnace basin, waste gas in the waste gas cavity heats premixed gas in the air inlet pipeline, and waste heat is brought back to the combustor through the premixed gas, so that the high-efficiency utilization of the waste heat is realized; the residual waste gas is finally discharged through a waste gas outlet, and the waste gas can be near a standby cold water container to heat the standby cold water, so that the waste heat can be reused.

According to the novel energy-saving gas stove with the waste heat recovery function, waste heat is fully utilized, a simple flame contact type heating mode is changed into a mode of combining a flame contact type heating mode and a heat radiation type heating mode, and almost all heat is absorbed by the pot bottom, so that heat loss is reduced, and the heat efficiency is comprehensively improved; the pot bottom is prevented from being overheated by a central fire-pressing mode, the combustion distance is increased by fire distribution at the periphery, full combustion is achieved, flame is dispersed, and uniform heating is achieved; through the design of the conical energy-gathering ring and the energy-gathering bulges, the heat generated by flame combustion is collected and gathered on the conical energy-gathering ring, and an energy-gathering isolating layer is added at the lower part of the conical energy-gathering ring, so that the waste caused by downward radiation of the heat is avoided, the heat of the conical energy-gathering ring is upwards radiated to realize efficient heat collection and is gathered at the bottom of the pot for the second time, and the problem of uneven heating is solved; this patent adopts the mode of waste gas down, and the waste gas waste heat is used for heating the gas in advance earlier, and the gas in advance takes the waste heat back to the combustor, promotes waste heat utilization ratio, because lower exhaust mode can not leave the gap between pot and stove basin, increases stove basin seal, on the one hand with the heat blockade in the stove basin, on the other hand has reduced the noise by a wide margin, has improved user experience.
