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 ga

Example Embodiment

Example one

1 and 2, an energy-saving gas stove includes a gas stove body 13, an igniter 14, a burner 1, a gas duct 2, and a gas mixing chamber 3 arranged on the gas stove body 13, and the igniter 14 is arranged at At the gas outlet of the combustor 1, the gas conduit 2 communicates with the gas mixing chamber 3, and the combustor 1 is connected to the upper part of the gas mixing chamber 3. It includes a cylindrical burner 11 and a cylindrical burner 11 The annular combustor 12 of the combustor 11 is provided with gas holes 111 on the side walls of the combustor 1. The gas stove also includes an exhaust gas discharge pipe 4, an air duct 5, cold air for inflow and hot exhaust gas discharged A heat exchange device 6 for heat exchange and an isolation cover 8 that separates the hot combustion gas from the outside. The isolation cover 8 is provided between the bottom of the pot 7 and the gas stove body 13, and one end of the exhaust gas exhaust pipe 4 is connected to the isolation...

Example two

6 and 7, the structure of this embodiment is basically the same as that of the first embodiment above. The main difference is that the gas stove of this embodiment also includes a high-temperature resistant fire shield 18, which is roughly inverted Goblet shape. The flame shield 18 is sleeved on the combustor 1, and a funnel-shaped hot gas outlet 181 is formed above the combustor 1. The funnel-shaped hot gas outlet 181 facilitates the diffusion of hot gas. The flame shield 18 has a certain blocking 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. At the same time, the heat formed by the combustion of the gas on the burner 1 is flushed from the hot gas outlet. And heat the bottom 7 of the pot.

Referring to FIG. 7, the gas stove further includes a bimetal 19 for sensing the hot gas of combustion and a flow control valve 191 controlled by the bimetal 19. The flo...

Example three

Referring to Figure 8, the structure of this embodiment is basically the same as that of the above-mentioned second embodiment. The main difference is that the partition 20 of this embodiment is provided with a plurality of vent holes 152 at intervals, and the pot bottom 7 is in contact with the top of the isolation cover 8. , There is a gap between the fire barrier 15 and the bottom of the pot 7. In this way, the combustion hot gas can be filled in the entire isolation cover 8, thereby increasing the heating area of ​​the bottom of the pot 7, thereby improving the thermal efficiency. In addition, the exhaust gas generated by combustion can also flow into the exhaust gas discharge pipe 4 from the vent 152, which is more conducive to the discharge of the 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 a heat 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

An energy-saving gas stove technical field [0001] The invention belongs to the technical field of gas stoves, in particular 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 Traditional gas stove mostly is that low-temperature gas is directly introduced into the burner to burn, because the air participating in combustion is not preheated, it is unfavorable for the complete combustion of gas, causing the burner to be easily carbonized; simultaneously, gas is in the process of burning , the carbon monoxide, carbon dioxide, incompletely burned natural gas and other waste gases produced directly spread 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, but also a lot of energy i...
