Problems solved by technology

The air preheater of the above-mentioned device needs to obtain heat from the burner, so it needs to consume a certain amount of heat energy; at the same time, because the device cannot discharge the exhaust gas such as carbon monoxide and carbon dioxide generated during the combustion of gas in time, the exhaust gas gradually accumulates in the isolation cover. Affects the air supply required for full combustion of the gas, and these exhaust gases will eventually overflow around the isolation enclosure, which will pose a safety hazard to human health
[0004] In addition, there is still such a problem in the existing gas stove that the temperature of the pot is easy to be too high when the gas stove burns, and then the food in the pot will produce harmful substances that are not conducive to human health, and even produce a large amount of carcinogens

Embodiment 1

[0031] refer to figure 1 with figure 2 , an energy-saving gas stove, comprising a gas stove body 13, an igniter 14, a burner 1 arranged on the gas stove body 13, a gas conduit 2, and a gas mixing chamber 3, and the igniter 14 is arranged at the gas outlet of the burner 1 , the gas conduit 2 communicates with the gas mixing chamber 3, and the burner 1 communicates with the upper part of the gas mixing chamber 3, which includes a cylindrical burner 11 and an annular ring surrounding the cylindrical burner 11. The burner 12 of the above-mentioned burner 1 is provided with a gas hole 111 on the side wall. The gas stove also includes a waste gas discharge pipe 4, an air duct 5, and a heat exchange device for heat exchange between the inflowing cold air and the discharged hot waste gas. The device 6 and the isolation cover 8 that isolates the combustion hot gas from the outside world, the isolation cover 8 is arranged between the bottom of the pot 7 and the gas stove body 13, one ...

Embodiment 2

[0040] refer to Image 6 with Figure 7 The structure of this embodiment is basically the same as that of the above-mentioned first embodiment, the main difference is that the gas stove of this embodiment also includes a high temperature resistant fire shield 18, and the fire shield 18 is roughly in the shape of an inverted goblet. The fire shield 18 is sleeved on the burner 1, and a funnel-shaped hot gas outlet 181 is formed above the burner 1, and the funnel-shaped hot gas outlet 181 is helpful for the diffusion of the hot gas. The fire shield 18 has a certain barrier effect on the flame, which can avoid the problem of uneven heating of the bottom 7 caused by the direct contact of the flame with the bottom 7 of the pot. out, and the bottom of the pot 7 is heated.

[0041] refer to Figure 7 , the gas cooker also includes a bimetal 19 for sensing combustion heat and a flow control valve 191 controlled by the bimetal 19 . The flow control valve 191 is installed on the gas ...

Embodiment 3

[0044] refer to Figure 8 , the structure of this embodiment is basically the same as that of the above-mentioned embodiment two, and its main difference is that a number of ventilation holes 152 are arranged at intervals on the partition plate 20 of this embodiment, and the bottom of the pot 7 is in contact with the top of the isolation cover 8, and the fireproof There is a gap between the layer 15 and the bottom of the pot 7 . In this way, the combustion hot gas can be filled inside the entire isolation cover 8, thereby increasing the heated area of ​​the bottom of the pot 7, and then improving the thermal efficiency. In addition, the exhaust gas generated by combustion can also flow into the exhaust gas discharge pipe 4 through the vent hole 152, which is more conducive to the discharge of exhaust gas.

Abstract

The invention discloses an energy-saving gas stove, which comprises a gas stove body, a combustor, a gas guide pipe and a gas mixing chamber, wherein the gas guide pipe is communicated with the gas mixing chamber and the combustor is communicated with the upper part of the gas mixing chamber. The gas stove additionally comprises an isolation hood, a waste gas exhaust pipe, an air guide pipe and aheat exchange device, wherein the isolation hood isolates combustion hot gas from the outside and the heat exchange device is used for heat exchange between incoming cold air and exhausted hot waste gas. The invention has the advantages that not only the gas is combusted more fully but also the thermal efficiency is effectively improved because heat contained in the waste gas produced during combustion is used for preheating the cold air participating in combustion, and the impact on body health caused by the waste gas is effectively avoided because the waste gas is fully exhausted. Moreover,since the heat generated by the gas in the closed gas combustion chamber is not rapidly dissipated around, the thermal efficiency of the gas stove is promoted.

Description

technical field [0001] The invention belongs to the technical field of gas stoves, and in particular relates to an energy-saving gas stove that can significantly improve gas combustion efficiency and simultaneously avoid the impact of combustion waste gas on human health. Background technique [0002] Most traditional gas stoves introduce low-temperature gas directly into the burner for combustion. Since the air participating in the combustion has not been preheated, it is not conducive to the complete combustion of the gas, causing the burner to easily carbonize; at the same time, during the combustion process of the gas, the generated Exhaust gases such as carbon monoxide, carbon dioxide, and incompletely burned natural gas spread directly around the cooker, seriously affecting the health of users; moreover, the heat energy generated by the combustion of this open traditional gas stove will also spread a lot around, not only the thermal efficiency is low , and waste a lot ...
