Regenerative energy-saving gas cooker

Abstract

The invention discloses a regenerative energy-saving gas cooker. The regenerative energy-saving gas cooker comprises a gas cooker main body, a burner, a sealing pot ring, a smoke recovery ring and a heat pipe heat exchanger, wherein the gas cooker main body is provided with a closed heat recovery chamber and a combustion chamber which is arranged at one side of the closed heat recovery chamber and provided with an upper opening; the burner is arranged in the combustion chamber of the gas cooker main body; the sealing pot ring is arranged on the upper opening of the combustion chamber of the gas cooker main body in a sealing manner, so that a closed space is formed in the combustion chamber; the smoke recovery ring is a hollow structural body with a plurality of air inlet holes and a smoke discharging opening and arranged outside the burner in the combustion chamber of the gas cooker main body; the heat pipe heat exchanger is arranged in the closed heat recovery chamber of the gas cooker main body, and is provided with an air inlet, a hot air outlet pipe, a smoke return pipe and a smoke discharging pipe and communicated with the burner and the smoke recovery ring. By adopting the regenerative energy-saving gas cooker, recovery of smoke heat and preheating of combustion-supporting air can be realized by virtue of the heat pip heat exchanger, the waste of waste heat can be avoided, and the heat efficiency can be improved.

Description

technical field [0001] The invention relates to the field of kitchen cooking utensils, in particular to a regenerative energy-saving gas stove. Background technique [0002] In recent years, with the enhancement of people's awareness of energy saving, heat energy recovery technology has been widely used in the construction and operation of large boilers, but this technology has not been applied in the design of small and medium-sized commercial gas stoves. The gas cooktops currently on the market have a large heat loss. The reasons are as follows: First, because the gas cooktops still use the traditional open combustion design, only part of the flame radiation is absorbed by the bottom of the pot, and the rest of the heat is directly emitted to the surroundings. In the air; the second is that the flue gas discharge temperature is too high, generally greater than 250°C, and a large amount of heat is directly discharged with the flue gas without being recycled.

[0002] In recent years, with the enhancement of people's awareness of energy saving, heat recovery technology has been widely used in the construction and operation of large boilers, but this technology has not been applied in the design of small and medium-sized commercial gas stoves

The gas cooktops currently on the market have a large heat loss. The reasons are as follows: First, because the gas cooktops still use the traditional open combustion design, only part of the flame radiation is absorbed by the bottom of the pot, and the rest of the heat is directly emitted to the surroundings. In the air; the second is that the flue gas discharge temperature is too high, generally greater than 250°C, and a large amount of heat is directly discharged with the flue gas without being recycled.

[0003] The utility model patent with the publication number CN201293363 discloses an energy-saving gas stove integrated with oil fume and heat recovery from the bottom. By setting up a heat recovery device, the heat recovery of the flue gas is preliminarily realized, but the gas stove has at least the following deficiencies: First, there is no Given the technical analysis and design scheme of the specific heat exchanger, it is impossible to accurately calculate and evaluate the energy-saving effect; second, a large amount of heat will be directly dissipated into the air; third, the recovery of the flue gas in the pot, although it can increase the recovery heat, but there is oil fume in the flue gas, which is easy to adhere to the heat exchange surface of the heat exchanger, reducing the heat exchange effect
