Description

Domestic high-efficiency energy-saving gas range

The utility model discloses a household high-efficiency energy-saving gas cooker which can be used by thousands of households. The household cooking stove is an innovative product on the basis of the traditional household cooking stove, belongs to the technical field of daily necessities, and also belongs to the technical field of daily mechanical products.

At present, domestic and foreign fuel resources are increasingly in shortage and are influenced by the shortage, and the price of household gas is increasing, so that research on gas cookers for saving gas and development of new gas sources are generally concerned. Therefore, the gas cooker develops an energy-saving device of the gas cooker and a far infrared energy-saving cooker, for example, a gas energy-saving device is arranged in a gas input pipe of the gas cooker; a refractory ceramic plate with fine sieve pores is arranged on the gas stove; placing a Ni-Cr metal net on a stove; rotary troughs are additionally arranged on the cooker hood and the adaptive burner nozzle holes to enable gas to be combusted in a rotary mode, and the rotary troughs play a certain energy-saving effect, but the energy-saving principle of the gas cooker is unreasonable, the energy-saving device is matched with the cooker according to a specified special operation method, a user cannot master the energy-saving principle, and the far infrared energy-saving cooker is only practically used for a pan; in addition, the production of the liquefied petroleum gas fuel source has high investment cost, complex production process and rising gas cost; the energy-saving effect of the gas cooker sold in the market is not obvious, the price of the gas is high, and the energy-saving device of the gas cooker needs to be improved.

The utility model aims at: in order to overcome the defects that the structure of the gas cooker is not reasonable enough and the energy (gas) saving efficiency is not obvious, the utility model designs a new high-efficiency energy-saving gas cooker according to the principle of physics, the production cost of the gas cooker is equivalent to that of the existing gas cooker, the gas cooker needs to have high efficiency and energy saving of gas, the energy saving rate of the gas cooker is higher than that of the general gas cooker sold in the market, the gas cooker has safe and reliable combustion when in use, and the pollution to the family environment is reduced; the product of the utility model is produced without changing the production process of the traditional gas cooker, and still reaches the product quality inspection standard of the national CJ4-83 gas cooker, and the traditional gas cooker can be updated.

The technical measures adopted for realizing the purpose of the utility model are as follows: the main components of the fuel gas are propane and propylene, which are combusted with oxygen according to the following reaction equation:

as can be seen from the above formula, oxygen is not available in the combustion, resulting in incomplete combustion of the fuel gas and pollution to the household environment. Therefore, the utility model discloses improve gas cooking utensils structure, increased economizer and improved pot support shape and set up the direction in gas cooking utensils's gas circuit to adapt to different grade type pot (including pan, round bottom iron pan, the aluminium pot of different diameters).

Specifically, the gas cooker of the utility model is formed by combining four main improved parts of an improved special pot support (1), a small burner spray head cover (2) without an upper fire hole, a small burner spray head nozzle (3) and an improved gas economizer (4) with an original gas cooker component, wherein the minimum inner diameter of the pot support (1) is ø mm, the maximum outer diameter is ø mm, the height of the pot support is 26mm, the pot support can be square four corners or circular five corners in production, the pot support inclines downwards for 4-5 degrees, the pot support not only keeps the national standard specified support height of 25mm, but also has the improved unique part, the support height difference is 18mm, therefore, the height difference between a ø 24 cm pot and the small burner is 10mm, the ø cm frying pot and the small burner are about 8mm in optimal heat conduction distance, the top of the unmodified small burner spray head cover is provided with four vertical fire holes which burn upwards, the four fire holes are closed after improvement, theoretically and practically heating the burner is reduced to the optimal position, the optimal heat conduction distance is reduced to the corresponding to the optimal heat conduction distance of the corresponding to the flame of the small burner, the flame is reduced from the flame, the flame is only reduced from the flame generated by the corresponding to the original flame generated by the original flame generated by the flame generated by adding of a linear burner, the flame generated by the linear jet head cover, the linear jet head (ZL, the flame generated by the linear burner, the flame generated by the linear jet head (3, the linear jet nozzle) of the linear burner, the flame generated by the linear burner, the linear burner is replaced linear burner, the.

Compared with the prior art, the utility model, the technological effect who has reached: the domestic high-efficiency gas energy-saving stove is subjected to repeated tests and expert argumentation for more than three years, is subjected to entrusted inspection of a gas appliance station by product quality supervision inspection in Wuhan City, and refers to the national gas stove CJ4-83 standard, and has the following main detection results:

(1) on a J2Y2938 stove of an oil stove electrically heated by using unmodified Guangdong kang Da brand stainless steel, 3000 grams of water is burnt by using an aluminum pot of ø 22 centimeters, the ambient temperature is 30 ℃, the temperature is from 40 ℃ to 80 ℃, the average temperature is three times, the gas consumption is 12.9 grids indicated by a gas meter, the time is 5 minutes and 11 seconds, and the height of a heat receiver from a combustor is 25mm according with the national unified regulation.

(2) When the utility model is used for stove tests, an aluminum pot with ø 22 centimeters is used for burning 3000 grams of water, the ambient temperature is 30 ℃, the average temperature is from 40 ℃ to 80 ℃, the average temperature is three times, the gas consumption is 9.15 grids indicated by a gas meter, the time spent is 5 minutes and 8 seconds, the burning flame is blue, and the height of a heat receiver from a burner is 10 millimeters.

(3) When the utility model is used, the stove is tested, 3000 g of water is burnt by using a stainless steel common frying pan with the diameter of ø 360mm, the continuous ignition is normal, the flame is blue in 30 minutes, the flame phenomenon is not generated, and the unsafe combustion phenomenon of yellow smoke is avoided.

The contrast test shows that the gas saving rate of the utility model can save coal gas by burning 3000 g of water is 29.1%, and the blue flame shows that the heat receiver reduces the high coal gas burning safety and the ignition is normal; the energy-saving effect is obvious, the reconstruction method is simple and easy to implement, the method is an effective way for updating old products, and the method plays a positive role in protecting the environment and the physical and mental health of family personnel and is certainly trusted by the vast number of new and old users.
