Description

Technical Field

[0001] The utility model relates to a burner for a gas stove, in particular to a fully up-draft gas burner. Background Art

[0002] As a key component in cooking equipment, the design and performance of a gas burner directly affect cooking efficiency, safety, and energy utilization efficiency. As an important design of a gas burner, the up-draft burner adopts a top-air supply method to improve the problems of low combustion efficiency and poor safety of traditional burners. However, although the up-draft burner performs excellently in some aspects, its design and structure still have the following deficiencies.

[0003] 1. In an up-draft burner, the nozzle seat usually includes one or more nozzles that inject gas into the gas burner for preliminary mixing with air. The design of the nozzles is crucial for the mixing effect. If the nozzle design is unreasonable, it will lead to uneven mixing of gas and air, affecting combustion efficiency and stability.

[0004] 2. To increase the heat load, the gas burner of an up-draft burner is usually equipped with two or more ejector pipes that are responsible for fully mixing gas and air. The number and design of the ejector pipes are key factors in improving combustion efficiency. However, an increase in the number of ejector pipes often leads to a large volume of the burner, which not only increases the manufacturing cost but may also affect the installation and layout of the burner.

[0005] 3. In some designs, to reduce the volume of the gas burner, the length of the ejector pipe is intentionally shortened. Although this design can reduce the volume of the burner, the shortened ejector pipe may cause the gas flow rate to be too fast, reducing the mixing time of gas and air, thereby affecting the mixing effect. If the mixing is not sufficient, it will lead to incomplete combustion, low thermal efficiency, and may also produce more harmful emissions. Therefore, it is necessary to make further improvements. Summary of the Utility Model

[0006] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a fully up-draft gas burner with a simple structure, convenient use, capable of achieving full and uniform mixing of gas and air, and effectively improving combustion efficiency.

[0007] The object of the utility model is achieved in the following way: A fully upward air intake gas burner head, which comprises a base. A mixing tube is horizontally arranged on the base. A gas nozzle is installed at one open end of the mixing tube. The other open end of the mixing tube is communicated with a main mixing groove. The main mixing groove is in a crescent shape with an open upper end. A mixing seat is covered and installed on the base. An outer ring mixing groove and an inner ring mixing groove with open tops are arranged on the mixing seat. An outer air inlet communicating with the main mixing groove is opened at the bottom of the outer ring mixing groove. The outer ring mixing groove and the inner ring mixing groove are communicated through an air intake groove. An outer ring burner cap and an inner ring burner cap are respectively covered on the outer ring mixing groove and the inner ring mixing groove. Gas is sprayed into the mixing tube through a gas nozzle. After the gas is uniformly mixed in the mixing tube, the main mixing groove, the air intake groove, the outer ring mixing groove and the inner ring mixing groove, it is sprayed out from the air outlet holes on the outer ring burner cap or the inner ring burner cap for combustion.

[0008] Further: A positioning clamping table extends upward on the mixing seat. Correspondingly, a positioning groove is arranged on the outer ring burner cap. After the outer ring burner cap is installed, the positioning groove is clamped into the positioning clamping table for fixation.

[0009] Further: The cross section of the positioning clamping table is in a "7" shape and is located on the inner circle of the outer ring mixing groove.

[0010] Further: A central mixing groove is also arranged at the center position of the top of the base. Correspondingly, the bottom of the inner ring mixing groove is hollowed out and communicated with the central mixing groove.

[0011] Further: A positioning table extends downward from the bottom of the inner ring mixing groove. The positioning table extends into the central mixing groove to play a role in central positioning of the mixing seat.

[0012] Further: The air intake groove includes an upper open groove arranged on the base and a lower open groove arranged at the bottom of the mixing seat. After the mixing seat is butted with the base, the upper open groove and the lower open groove enclose a rectangular hollow air intake groove.

[0013] Further: The gas nozzle is installed on a nozzle seat. The nozzle seat is horizontally installed at the air intake end of the mixing tube. The nozzle seat and the mixing tube are spaced apart to form an air intake groove therebetween.

[0014] Further: An air intake seat extends downward from the nozzle seat. The interior of the air intake seat is hollowed out to form an air inlet pipe. The gas nozzle is installed at the air outlet end of the air inlet pipe.

[0015] The beneficial effects of the utility model are: 1. The structure is simple, the production cost is low, and the market competitiveness is improved.

[0016] 2. In this design, the gas is sprayed into the ejector tube through the gas nozzle and is preliminarily mixed with air. The design of the ejector tube ensures that the gas and air start to mix before entering the main mixing tank, guaranteeing the preliminary mixing uniformity. The preliminary mixing in this step lays the foundation for subsequent more thorough mixing and significantly improves the combustion efficiency.

[0017] 3. The preliminary mixed gas of gas and air enters the main mixing tank. Since the volume of the main mixing tank is significantly larger than that of the ejector tube, the flow rate of the mixed gas is significantly reduced. This design greatly reduces the kinetic energy of the mixed gas and provides a stable environment for the gas and air to mix more fully. The reduction in flow rate not only improves the mixing effect but also avoids the problem of incomplete combustion caused by too high a gas flow rate.

[0018] 4. The gas that has been preliminarily and fully mixed in the main mixing tank partially enters the outer ring mixing tank, inner ring mixing tank, and intake tank directly and is mixed again. This primary and secondary mixing process ensures that the mixed gas has reached a very high mixing uniformity before entering the burner cap. Through the multi-level and multi-channel design, the mixed gas can enter the burner cap more evenly, thereby further improving the combustion sufficiency and efficiency.

[0019] 5. The above design concept ensures the full mixing of gas and air at multiple stages and multiple positions, enabling the gas to burn fully, reducing the phenomenon of incomplete combustion, and significantly improving the combustion efficiency. This not only improves the thermal efficiency of the gas burner head, saves energy, but also reduces the emission of harmful gases and improves the environmental friendliness.

[0025] The present utility model will be further described in detail below with reference to the accompanying drawings. A fully upward air intake gas stove burner, which comprises a base 1, an ejector tube 2 is horizontally arranged on the base 1, a gas nozzle 3 is installed at one open end of the ejector tube 2, and the other open end of the ejector tube 2 is communicated with a main gas mixing groove 4. The main gas mixing groove 4 is in a crescent shape with an upper opening; a gas mixing seat 5 is covered and installed on the base 1. An outer ring gas mixing groove 51 and an inner ring gas mixing groove 52 with top openings are arranged on the gas mixing seat 5. An outer air intake 53 is opened at the bottom of the outer ring gas mixing groove 51 and is communicated with the main gas mixing groove 4. The outer ring gas mixing groove 51 and the inner ring gas mixing groove 52 are communicated through an air intake groove 54. An outer ring burner cap 6 and an inner ring burner cap 7 are respectively covered on the outer ring gas mixing groove 51 and the inner ring gas mixing groove 52; gas is sprayed into the ejector tube 2 through a gas nozzle. After the gas is uniformly mixed in the ejector tube 2, the main gas mixing groove 4, the air intake groove 54, the outer ring gas mixing groove 51 and the inner ring gas mixing groove 52, it is sprayed out from the air outlet holes on the outer ring burner cap 6 or the inner ring burner cap 7 for combustion.

[0026] In one embodiment: a positioning clamping platform 55 extends upward on the gas mixing seat 5. Correspondingly, a positioning groove 61 is arranged on the outer ring burner cap 6. After the outer ring burner cap 6 is installed, the positioning groove 61 is clamped into the positioning clamping platform 55 for fixation.

[0027] In one embodiment: the cross section of the positioning clamping platform 55 is in a "7" shape and is located on the inner circle of the outer ring gas mixing groove 51.

[0028] In one embodiment: a central gas mixing groove 11 is further arranged at the central position of the top of the base 1. Correspondingly, the bottom of the inner ring gas mixing groove 52 is hollowed out and communicated with the central gas mixing groove 11.

[0029] In one embodiment: a positioning platform 56 extends downward at the bottom of the inner ring gas mixing groove 52. The positioning platform 56 extends into the central gas mixing groove 11 to play a role in central positioning of the gas mixing seat 5.

[0030] In one embodiment: The intake air groove 54 includes an upper opening groove 12 provided on the base 1 and a lower opening groove 57 provided at the bottom of the air mixing seat 5. After the air mixing seat 5 is docked with the base 1, the upper opening groove 12 and the lower opening groove 57 enclose a rectangular hollow intake air groove 54.

[0031] In one embodiment: The gas spray head 3 is installed on the spray head seat 31. The spray head seat 31 is installed in parallel at the air intake end of the ejector pipe 2. The spray head seat 31 and the ejector pipe 2 are spaced apart, and an intake air groove 54 is formed therebetween.

[0032] In one embodiment: The spray head seat 31 extends downward to form an intake air seat 32. The interior of the intake air seat 32 is hollow to form an intake pipe, and the gas spray head 3 is installed at the air outlet end of the intake pipe.

[0033] Working principle: In this case, gas is sprayed into the ejector pipe 2 through the gas spray head 3. A gas spray head 3 is installed at one open end of the ejector pipe 2, and the gas is sprayed into the ejector pipe 2 at a high speed. During this process, the surrounding air is introduced and preliminarily mixed with the gas. The ejector pipe 2 serves as a channel for the preliminary mixing of gas and air, ensuring that the gas has been mixed with a certain amount of air before entering the main air mixing groove 4.

[0034] The preliminarily mixed gas enters the main air mixing groove 4 from the other open end of the ejector pipe 2. The main air mixing groove 4 is in the shape of a crescent with an upper opening, and its volume is significantly larger than that of the ejector pipe 2. Due to the relatively large volume of the main air mixing groove 4, the flow rate of the mixed gas entering it is significantly reduced, and the kinetic energy decreases, thereby providing a stable environment for the gas and air to mix more fully. In the main air mixing groove 4, the reduction of the gas flow rate and the stable mixing environment ensure a higher mixing uniformity of the gas and air, laying a foundation for the subsequent combustion process.

[0035] The fully mixed gas is diverted from the main air mixing groove 4 into the outer ring air mixing groove 51, the inner ring air mixing groove 52, and the intake air groove 54. The outer ring air mixing groove 51 and the inner ring air mixing groove 52 are respectively covered and installed with an outer ring burner cap 6 and an inner ring burner cap 7. An outer air intake port 53 is opened at the bottom of the outer ring air mixing groove 51, which is communicated with the main air mixing groove 4 to ensure that the gas can smoothly enter the outer ring air mixing groove 51. In addition, the outer ring air mixing groove 51 and the inner ring air mixing groove 52 are communicated through the intake air groove 54, so that the mixed gas is uniformly mixed again before entering the burner cap.

[0036] The gas uniformly mixed in the outer ring air mixing groove 51 and the inner ring air mixing groove 52 is respectively ejected from the air outlet holes on the outer ring burner cap 6 and the inner ring burner cap 7 for combustion. This design makes the combustion of the burner cap more stable and uniform, and the flame presents an ideal shape. Since the gas and air have been fully mixed before entering the burner cap, the combustion process is very complete, efficient, reducing the phenomenon of incomplete combustion and improving the combustion efficiency.

[0037] Among them, a positioning boss 55 extends upward on the gas mixing base 5. Correspondingly, a positioning groove 61 is provided on the outer ring burner cap 6. After the outer ring burner cap 6 is installed, the positioning groove 61 is snapped into the positioning boss 55 for fixation. The cross-section of the positioning boss 55 is in the shape of a "7" and is located on the inner circle of the outer ring gas mixing groove 51. This design ensures the precise positioning and stability of the burner cap during installation.

[0038] In addition, a positioning platform 56 extends downward from the bottom of the inner ring gas mixing groove 52. The positioning platform 56 extends into the central gas mixing groove 11 to play a role in central positioning of the gas mixing base 5. The air inlet groove 54 includes an upper opening groove 12 provided on the base 1 and a lower opening groove 57 provided at the bottom of the gas mixing base 5. After the gas mixing base 5 is docked with the base 1, the upper opening groove 12 and the lower opening groove 57 enclose a rectangular hollow air inlet groove 54. The open structure enables the product to be cast without a complex core-pulling structure during molding, which is beneficial to reducing production costs.

[0039] Furthermore: The gas nozzle 3 is installed on the nozzle seat 31. The nozzle seat 31 is installed in parallel at the air inlet end of the ejector pipe 2. The nozzle seat 31 and the ejector pipe 2 are spaced apart to form the air inlet groove 54 therebetween. The nozzle seat 31 extends downward with an air inlet seat 32. The interior of the air inlet seat 32 is hollow to form an air inlet pipe. The gas nozzle 3 is installed at the air outlet end of the air inlet pipe. This design ensures the stable connection between the gas nozzle and the ejector pipe and the smooth flow of gas.

[0040] In summary, through the ingenious structural design, the present invention realizes the multi-level and full mixing of gas and air, ensures the efficient and full combustion of gas, and improves the combustion efficiency and stability. This design not only optimizes the performance of the gas burner head but also improves the safety and convenience of use, having broad application prospects and market value.

[0041] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the claims of the present invention.
