Description

Technical Field

[0001] The invention belongs to the technical field of household gas stoves, and in particular relates to a high-efficiency gas stove system with double premixing. Background Art

[0002] A gas stove is a cooking device that uses natural gas, liquefied petroleum gas and other gases as fuel. It is mainly composed of a stove body, a gas nozzle, an ignition device, a stove cover and a control valve. Its working principle is to generate flames after the gas is ignited, directly heating the pot to achieve cooking. However, with the continuous improvement of users' requirements for energy saving and safety of kitchen appliances, traditional stoves have gradually failed to meet users' expectations. Traditional gas stoves use gas fuels such as liquefied petroleum gas, artificial gas, and natural gas, which cannot be fully mixed with air during use, resulting in incomplete fuel combustion and low gas utilization. Therefore, a high-efficiency gas stove system with double premixing is needed.

[0003] Existing gas stoves usually adopt a single premixing method, that is, the gas and air are premixed once through the gas nozzle before combustion. This design improves the combustion efficiency of the gas to a certain extent, but due to the limited mixing effect of the gas and air, it is often difficult to achieve the ideal combustion effect. In addition, the concentration of carbon monoxide (CO) in the exhaust gas generated during the combustion process is high, the emission is not environmentally friendly, and the gas utilization rate is still low. Specifically, this single premixing gas stove includes the following main parts:

[0004] 1. Gas nozzle: used to inject gas into the burner.

[0005] 2. Primary air inlet: When the gas is injected, the air mixes with the gas through the inlet.

[0006] 3. Burner: Gas is mixed with air and ignited in the burner to produce flame for cooking.

[0007] Existing technical problems:

[0008] 1. Low combustion efficiency:

[0009] In the existing gas stove design, the mixing effect of gas and air is limited. The one-time premixing method cannot ensure that the gas and air are fully mixed, resulting in low gas utilization during the combustion process and low combustion efficiency.

[0010] 2. Exhaust emission issues:

[0011] Due to incomplete mixing of gas and air and incomplete combustion, existing gas stoves will produce high concentrations of harmful gases such as carbon monoxide (CO) during use, which not only affects the air quality of the cooking environment, but also poses a safety hazard.

[0012] 3. Insufficient thermal efficiency:

[0013] The uneven mixing of gas and air and the unstable flame temperature lead to insufficient thermal efficiency. Users often need to spend longer time to achieve the desired cooking effect, which affects the user experience.

[0014] 4. High energy consumption:

[0015] The low combustion efficiency directly leads to an increase in gas consumption, which increases energy consumption and user costs. The energy efficiency of traditional gas stoves is difficult to meet the current energy-saving and environmental protection needs.

[0016] These problems show that the existing gas stove design has obvious deficiencies in combustion efficiency, exhaust gas emissions, thermal efficiency and energy consumption, and cannot fully meet the needs of modern users for energy saving, environmental protection, safety and efficiency. Therefore, it is urgent to develop an efficient gas stove system with dual premixing function to solve these problems and improve the overall performance of the gas stove. Summary of the invention

[0017] In view of the problems existing in the prior art, in order to meet and improve the gas utilization efficiency and increase the safety performance, the present invention provides a high-efficiency gas cooktop system with double premixing.

[0018] The present invention is implemented as follows: a high-efficiency gas stove system with double premixing, comprising a stove body, a gas system, and a safety control system;

[0019] The stove body is in the form of a square frame, including a stove head, a bracket, a stove head, a burner head, and a premixing chamber; the inner and outer walls of the stove head and the bracket are made of 304 stainless steel, which is easy to clean; the stove head and the burner head are made of cast iron, which is resistant to high temperature and corrosion; the premixing chamber is located below the burner head, including an upper blade, a lower blade, a rotating shaft and a shell; the upper blade and the lower blade rotate coaxially through the rotating shaft to mix the gas-air mixture more evenly, so as to achieve the effect of secondary premixing;

[0020] The gas system includes a turbocharged premixing fan, a gas check valve, a main gas pipeline, and a normally open flame gas pipeline; the turbocharged premixing fan includes an air inlet, a gas inlet, a gas-air outlet, and a volute, and air and gas enter the fan from their respective inlets and are mixed in the volute under the action of their blades to achieve the effect of first premixing;

[0021] The safety control system includes an integrated valve, a double flameout electromagnetic protection valve, and a control panel; the integrated valve can simultaneously control the gas intake volume and the speed of the fan, and under the action of the control panel, always maintain the optimal ratio to achieve the purpose of full combustion; the double flameout electromagnetic protection valve includes a leakage flameout electromagnetic protection valve, a gas leakage flameout electromagnetic protection valve and a manual regulating valve, which are used to urgently cut off the gas input in the event of leakage or gas leakage to ensure the safety of users.

[0022] Another object of the present invention is to provide a high-efficiency combustion method of a high-efficiency gas cooktop system with double premixing, comprising:

[0023] (1) Turn on the gas delivery switch and rotate the integrated valve. At this time, the turbocharger premixing fan system starts to work. The gas and air enter the volute at the same time and are mixed under the action of the fan to achieve the effect of the first premixing.

[0024] (2) The gas pipeline is divided into two parts, namely, the constant open flame pipeline and the main gas pipeline. The constant open flame pipeline is used for the continuous output of the constant open flame of the stove, thereby reducing the number of large fires; the main gas pipeline passes through the premixing chamber under the stove. Under the action of two blades, the gas-air mixture is evenly mixed to achieve the effect of secondary premixing;

[0025] (3) The rotating integrated valve controls the gas output rate and fan speed at the same time, and under the action of the control panel, always maintains the optimal ratio to achieve the purpose of full combustion.

[0026] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0027] First, the present invention provides a high-efficiency gas stove system with double premixing. A turbocharged premixing fan system and a premixing chamber, i.e., a double premixing device, are provided to make the gas fuel more sufficient. At the same time, a double flameout electromagnetic protection valve and an energy-saving control system are provided to achieve the purpose of efficient combustion and safe use.

[0028] (1) This device is equipped with a turbocharged premixing fan system, which breaks through the traditional single air inlet and sets the gas and air inlets at the fan inlet. The brushless DC variable frequency fan completes the first premixing of the two in the volute;

[0029] (2) This device is equipped with a second premixing system, which is located directly below the burner head. Two fans in the premixing chamber further mix the gas-air mixture to make the gas fuel more complete;

[0030] (3) This device is equipped with an energy-saving control system, and the user can manually change the valve size to control the firepower. By controlling the calculation of the main board, the user can simultaneously control the gas intake volume and the fan speed, so that the two always maintain the best mixing ratio to achieve the purpose of efficient combustion.

[0031] (4) The device is equipped with a double flameout electromagnetic protection valve. By equipping it with a gas sensor and a leakage protector, the device will automatically shut down in time in the event of a gas leak or a leakage, ensuring the safety and health of the user;

[0032] Second, the embodiment of the present invention provides a high-efficiency gas stove system with double premixing, which aims to solve the problems of traditional gas stoves in combustion efficiency, thermal efficiency, exhaust gas emissions, safety, etc. Traditional gas stoves usually use a single premixing technology, which leads to insufficient mixing of gas and air, incomplete combustion, a high concentration of carbon monoxide (CO), low thermal efficiency and high energy consumption. In addition, the safety of traditional gas stoves is poor, lacking an effective safety control system, and unable to respond to dangerous situations such as gas leakage and electric leakage in a timely manner.

[0033] 1. Application of double premixing technology:

[0034] The present invention solves the problem of uneven mixing of gas and air by introducing double premixing technology. First, the turbocharged premixing fan achieves preliminary mixing of gas and air through its volute structure to form a gas-air mixture; second, the upper and lower blades in the premixing chamber further mix the gas evenly to achieve a higher mixing uniformity. The double premixing technology significantly improves combustion efficiency, reduces unburned gas emissions, and improves overall thermal efficiency.

[0035] 2. High efficiency and energy saving:

[0036] Due to the application of double premixing technology, the gas and air are mixed more evenly and burn more fully, which significantly improves the utilization rate of gas, reduces gas consumption, and achieves energy-saving effects. In addition, the design of the integrated valve enables the gas intake volume and fan speed to be automatically adjusted to always maintain the best combustion state, further improving the energy-saving performance of the system.

[0037] 3. Security Improvement:

[0038] The present invention integrates a double flameout electromagnetic protection valve in the gas stove system, which can quickly cut off the gas supply in the event of a power or gas leak to avoid safety accidents. At the same time, the integrated valve and control panel equipped in the system further ensure the stability and safety of combustion by accurately controlling the ratio of gas to air.

[0039] 4. Environmental protection improvement:

[0040] By optimizing the mixing ratio of gas and air and the combustion process, the present invention effectively reduces the emission of harmful gases such as carbon monoxide, improves the combustion emission quality, and meets the current environmental protection requirements. The system reduces the harmful components in the exhaust gas through full combustion and reduces pollution to the environment.

[0041] 5.Structural optimization:

[0042] The present invention uses high temperature resistant and corrosion resistant materials, such as 304 stainless steel for the stove body and cast iron for the stove head and burner, which not only increases the durability of the system but also facilitates cleaning and maintenance. The design of the premixing chamber and turbocharged premixing fan is also optimized to ensure the stability and efficiency of the entire system.

[0043] Through the above technical advances, the present invention greatly improves the performance of gas stoves, solves the problems of incomplete combustion, low energy efficiency, poor safety, etc. of traditional gas stoves, and has significant innovation and application prospects.

[0056] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0057] like Figure 1 As shown, an embodiment of the present invention provides a high-efficiency gas stove system with double premixing, comprising a stove body 1, a gas system 2, and a safety control system 3;

[0058] like Figure 5 As shown, the stove body 1 is a square frame as a whole, including a stove head 11, a bracket 12, a stove head 13, a burner head 14, a premixing chamber 15 ( Figure 6 ); the inner and outer walls of the stove top head 11 and the bracket 12 are made of 304 stainless steel, which is easy to clean; the stove head 13 and the burner head 14 are made of cast iron, which is resistant to high temperature and corrosion; the premixing chamber 15 is located below the burner head 14, and includes an upper blade 151, a lower blade 152, a rotating shaft 153 and a shell 154. The upper blade 151 and the lower blade 152 rotate coaxially through the rotating shaft 153 to mix the gas-air mixture more evenly to achieve the effect of secondary premixing;

[0059] The gas system 2 includes a turbocharger premixing blower 21 ( Figure 2 ), a gas check valve 22, a main gas pipeline 23, and a constant open flame gas pipeline 24; Figure 3 , 4 As shown, the turbocharger premixing fan 21 includes an air inlet 211, a gas inlet 212, a gas-air outlet 213, and a volute 214. Air and gas enter the fan from their respective inlets and are mixed in the volute 214 under the action of their blades to achieve the effect of primary premixing.

[0060] The safety control system 3 includes an integrated valve 31, a double flameout electromagnetic protection valve 32, and a control panel 33; Fig. 9 As shown, the integrated valve 31 can simultaneously control the gas intake and the speed of the fan, and under the control of the electric plate 33, always maintain the best ratio to achieve the purpose of full combustion; Figure 7 As shown, the dual flameout electromagnetic protection valve 32 includes an electric leakage flameout electromagnetic protection valve 321, a gas leakage flameout electromagnetic protection valve 322 and a manual regulating valve 323, which are used to urgently cut off the input of gas in the event of electric leakage or gas leakage to ensure the safety of users.

[0061] The high-efficiency gas stove system provided by the embodiment of the present invention realizes efficient combustion and safety control through double premixing technology. First of all, the design of the stove body ensures the durability and easy cleaning of the overall structure. The stove head and burner are made of cast iron material, which can withstand high temperature and corrosion, so that the system can still maintain stable operation in a high temperature environment. The premixing chamber is located below the burner, and upper and lower blades are arranged inside. Through the coaxial rotation of the rotating shaft, the secondary full premixing of gas and air is realized, thereby ensuring the uniform mixing of the gas, laying the foundation for efficient combustion.

[0062] In the gas system, the turbocharger premixing fan plays a key role. Air and gas enter the fan from separate inlets and are premixed for the first time in the volute through the action of the blades. This preliminary mixing process allows the gas and air to be evenly combined, thereby improving the combustion efficiency and reducing the exhaust gas emissions caused by incomplete combustion. The premixed gas-air mixture enters the premixing chamber through the outlet of the fan for further mixing.

[0063] The safety control system ensures the safety of the system through multi-level protection measures. The integrated valve is responsible for adjusting the gas intake and the speed of the fan. With the help of the control panel, the mixing ratio of gas and air is always kept in the best state, thus achieving the effect of full combustion. In addition, the double flameout electromagnetic protection valve can quickly cut off the gas supply when the system detects leakage or gas leakage to prevent accidents. At the same time, the manual regulating valve also provides users with manual operation methods in emergency situations, further improving the safety of the system.

[0064] In summary, this high-efficiency gas stove system not only improves combustion efficiency and thermal energy utilization by optimizing the mixing process of gas and air, but also makes significant improvements in user safety. This design enables the system to provide stable, efficient and safe combustion effects in actual use, and is suitable for various home and commercial kitchen scenarios.

[0065] like Figure 8 As shown, an embodiment of the present invention provides a high-efficiency combustion method of a high-efficiency gas stove system with double premixing, comprising:

[0066] (1) Turn on the gas delivery switch and rotate the integrated valve. At this time, the turbocharger premixing fan system starts to work. The gas and air enter the volute at the same time and are mixed under the action of the fan to achieve the effect of the first premixing.

[0067] (2) The gas pipeline is divided into two parts, namely, the constant open flame pipeline and the main gas pipeline. The constant open flame pipeline is used for the continuous output of the constant open flame of the stove, thereby reducing the number of large fires; the main gas pipeline passes through the premixing chamber under the stove. Under the action of two blades, the gas-air mixture is evenly mixed to achieve the effect of secondary premixing;

[0068] (3) The rotating integrated valve controls the gas output rate and fan speed at the same time, and under the action of the control panel, always maintains the optimal ratio to achieve the purpose of full combustion.
