Description

Oxygen-increasing vertical gas channel gas stove

technical field

The utility model relates to a cooker for burning coal gas, natural gas, liquefied petroleum gas and artificial gas, in particular to a vertical gas channel gas cooker with the function of increasing oxygen and supporting combustion.

Background technique

Existing various gas-cookers all are to adopt jet nozzle, and air duct is laid flat, and gas is sprayed horizontally at first in a section of relatively long horizontal air duct, and then laterally ejects and burns from the ring-shaped fire cap. There are following weak points in this class gas cooker:

1. An air intake adjustment device must be installed at the inlet of the horizontal airway. The air intake volume cannot be adjusted too large or too small, otherwise the combustion will be poor or the flame will be separated. Since the gas pressure fluctuates during use, it is difficult to adjust the air intake volume properly and match the gas pressure at all times, so the gas cannot be fully combusted or flame-out occurs.

2, the area that the annular flash cap causes flame to radiate heat outwards is large, often exceeds the area of cooker bottom surface, causes heat utilization efficiency to be less than 60%.

3. Because the flame burns from the fire cap for a long time, the temperature of the fire cap and the air passage is higher, and it is easy to rust and form carbon, and the carbon formation falls off and blocks the air passage, so that the gas is leaked, so safety accidents are prone to occur. In addition, insects are easy to crawl into and stay at the airway and valve, which also cause safety accidents due to blockage.

4. There is a gap between the stove surface and the burner, and oil, sundries and water can easily enter the stove, causing pollution, and it is difficult to clean, which is not environmentally friendly and hygienic.

5. Long-term high-temperature carbon formation or deformation in the fire cap and stove, the energy-saving effect will be worse after half a year of use.

6. The main flame burns in the place where there is no water around the bottom of the pot. The cooking is easy to burn and produce oily smoke, which is harmful to human health.

7. In the hot summer, due to the large heat dissipation, the high temperature in the kitchen is very hot, and the heat is unbearable, and it is easy to burn the handle of the cooker.

8. It is difficult to adapt to the use of various pressure gases, and the air conditioning board needs to be adjusted at any time, which is difficult to operate.

Contents of the invention

The purpose of the utility model is to provide a gas stove with a vertical gas channel with oxygen-increasing and combustion-supporting functions, so that the gas can be fully and completely burned, the heat energy utilization rate is high, the safety performance is good, and it is not easy to pollute.

The utility model includes a stove shell, a gas control valve, an ignition device and a flameout protection device. It is connected to the outlet of the gas control valve through a conduit. There are 2 or more large and evenly distributed air inlet holes on the bottom plate of the conical oxygen storage tank. The isolation cylinder with the vertical air channel is nested between the oxygen storage tank and the gas oxygen tank. In the middle of the mixing chamber, the isolation cylinder is fixed with ignition and flameout protection devices. The ignition needle and flameout protection needle are installed on the top plate of the isolation cylinder. The support arm is used to fix the entire combustion device. The conical flash cap with evenly distributed gas injection holes on the top plate is set on the isolation cylinder to form a gas-oxygen mixing chamber. On the conical fire cap, its bottom surface is close to the cooktop of the cooker shell.

The working principle is as follows: the gas is sprayed upwards from the nozzle. According to the principle of low pressure of high-speed air flow in fluid mechanics, the gas will drive the air in the oxygen storage bin through the vertical air channel and enter the inner cavity of the conical cap. The gas and oxygen are mixed in the mixing chamber, and finally ejected from the nozzle hole of the conical fire cap, forming a jet combustion at a height of 5 mm from the conical cap.

Compared with the prior art, the utility model has the following characteristics:

1. The gas is fully and completely burned to save energy.

Because the air inlet holes on the floor of the oxygen storage bin are large or many, the oxygen content in the oxygen storage bin is large, which can fully meet the combustion needs, so the gas is fully and completely combusted, increasing heat energy and saving energy.

2. The thermal efficiency is as high as 80%.

Because the gas is jet-burned at the center of the bottom of the cooker, the heat is concentrated and the radiation is less, so the thermal efficiency is as high as 80%. After testing, compared with some domestic brands of stoves, other brand stoves can boil 10 jin of water with gas, the utility model can boil 16 jin of water, the time is equal, and the energy-saving efficiency is as high as more than 50%.

3. It is safe and reliable, eliminating the phenomenon of airway blockage.

Because the flame burns more than 5 mm away from the conical cap, there is no high temperature at the conical cap and the vertical air passage, so there will be no air passage blockage accident due to carbon formation. In addition, any bugs and sundries cannot stay in the vertical air duct, and will automatically fall out of the stove. In short, no airway blockage will occur, and it is safe and reliable.

4. Clean and hygienic, prolong the service life of the stove.

Since the cooking surface is closed by the conical protective cover, oil, debris and water will not enter the cooking surface, and the oil, debris and water falling on the smooth cooking surface can be easily removed, so the cooking surface can be kept clean and hygienic . In addition, it is difficult for substances such as corrosive gas and salt water to enter the stove, and the stove does not generate high temperature, so the service life of the stove can be extended.

5. There is no high temperature, no carbon formation, no deformation in the fire cap and the stove, and it can maintain high efficiency and energy saving for a long time.

6. The flame is jet-burned from the bottom of the pot to the surroundings, and there is water in the bottom of the pot. Therefore, cooking does not burn the sides and reduces oily smoke, which is beneficial to personal health.

7. Less heat dissipation, the heat energy is absorbed by the cooker. This cooker can reduce the temperature of the kitchen by more than 10 degrees, and the handle of the cooker will not be easily burned, which has a protective effect on the cooker.

8. Sufficient oxygen supply, full combustion, and concentrated combustion, will not cause gas separation and non-combustion. Therefore, all kinds of gases can be completely burned.
