Description

Flame visibility and safety gas burner

The invention mainly discloses a combustion device, in particular a gas combustion device which utilizes a flow guiding component to improve flame visibility and safety.

Traditional space heating devices are divided into two categories: electricity and non-electricity. Both devices have their own advantages and disadvantages. In general, an air-conditioning device that is heated by combustion can generate a large amount of heat in a short period of time without increasing the electrical load of the regional power system. Typical commercial heating and heating facilities include electrical heating and fireplaces, and fire pits. The number of indoor air conditioners that are heated by combustion at high latitudes is no less than that of electrically heated air conditioners. Outdoors such as gardens and terrace heating units are dominated by combustion heating. Since the electric heater equipment must be equipped with a high-load circuit and a heating pipeline system, the equipment itself is expensive and must use the power input energy, and high load current needs to be considered. Therefore, in addition to the company's office, the home user is used. not much. In the middle and high latitudes, especially in the high latitude countries, the general home heating and heating devices use more burner combustion heating devices, which are convenient to use and the overall cost is lower. Traditional indoor and outdoor combustion furnaces are often fueled by cordwood, pellets, or propane natural gas. In recent years, due to environmental considerations, natural gas is the cleanest source of energy compared to the combustion efficiency and carbon dioxide emissions of wood, fuel blocks, and natural gas, and it has the lowest carbon emissions per unit of heat. The use of wood has gradually become considered a less environmentally friendly fuel. Take 2012 sales as an example. More than 70% of newly sold fireplaces in North America Use natural gas as a fuel. However, in recent years, the flame-burning device is not only simply heated, but also has a combination of decoration and atmosphere. Therefore, the combustion device with high efficiency and aesthetics of flame is gradually gaining importance in the market.

At present, the gas flame burning device controls or changes the shape of the flame to change the nozzle distribution mode, or the device plus the transparent mask as the diversion, and the introduction of the external airflow control by the chimney effect or the change of the flame shape is more common. However, in addition to the swirling shape of the flame, the flame can only extend upward in a line manner, and cannot change in the lateral direction. There are also shortcomings in the common flame scale, easy to accumulate gas, and the device accumulates high heat. The main reason is that the mask can shield part of the external airflow and prevent the flame from being directly affected by the ambient airflow, so as to maintain a specific flame shape. However, the use of such a semi-closed mask is accompanied by the disadvantage of air non-circulation and overheating. Since the general mask needs to provide a shielding function, generally only the upper and side openings are open for air circulation. If the opening is too large, the main function of shielding the airflow is lost; if the opening is too small, it can provide better airflow shielding effect, but it also causes heat and exhaust gas generated during combustion to be easily lost. If the fresh air is not replenished in time in the mask, the flame will be extinguished, or black smoke or even toxic gas will be generated due to incomplete combustion. At the same time, if the air flow in the mask is insufficient, effective heat dissipation cannot be achieved. When the heat generated during combustion cannot be balanced by the heat dissipation capability that can be achieved by the device, the longer the use time, the higher the temperature of the device as a whole.

If the transparent mask is not used, the nozzle is sprayed in a way that is susceptible to ambient airflow, the flame is not controlled, and the flame pattern is extremely limited. Rather than the two common ways of changing the shape of the flame, the more specific way is to actively control the flame shape by electromagnetic, but the structure of such a device is complicated and expensive, and is currently limited to controlling the flame with a small combustion scale, due to no mask, It is also susceptible to environmental airflow and is currently limited to the experimental phase. There are no commercial products.

Please refer to the "VORTEX TYPE GAS LAMP" patent of U.S. Patent No. 7,097,448, which discloses a scroll type gas lamp for combustible gas to generate an upward vortex flame, the vortex flame being located around It is limited to the boundary of the vortex air. During the operation, there is an interface between the vortex air without gas and the central region surrounded by gas, and the gas is burned inside. The gas lamp has an axis and includes: a base having a surface extending laterally along the central axis; a shield including a first and a second axially extending section Each block has an upper end and a lower end, and the lower end of each block is fluid-tightly coupled to the base, each block forming a cut-off wall, and the cut-off wall has an arc inner wall and an arc shape An outer wall, the first and second blocks alternately overlapping and their edges are adjacent to each other and spaced apart to form tangential air ports, thereby forming an axially extending chamber, the chamber being ported The sides are open; the first and second blocks are arranged and arranged at the base and surround the entrance of the combustible gas; the gas combines with the air entering from the port for combustion, the burning gas forms a flame, flame and arc The inner walls are separated, and the air does not allow gas to flow to the ports.

However, with the shroud of the above structure, the outside air enters the inside of the shroud via the opposite two ports. Such a design can only provide continuous combustion of the flame, and is susceptible to instability caused by the air flow around the device in practical applications, resulting in instability. It is difficult to maintain a stable flame height and a vortex shape, and the flame flame effect can be formed only when the flame scale is within a certain range. If the flame scale is small or the shield length is not long enough, a remarkable rotating flame effect cannot be formed. Only a small portion of the externally inhaled cold air flows through the surface of the combustion device, which causes the device to accumulate high temperatures. In addition to this, since the bottom of the device is a closed end, a semi-closed region is formed near the combustion head with the surrounding glass. Since the combustion device is started, gas supply must be started first, and an appropriate concentration of ignition is formed in the gas to smoothly ignite the device. If the ignition is too early, the gas concentration will be too low to be able to click, and because the gas specific gravity is greater than the air, it is easy to accumulate in The bottom of the device. If it is too late, it may cause a gas explosion due to excessive gas concentration. Or when the device is just turned off but immediately starts to burn, it cannot be ignited smoothly due to internal oxygen deficiency, and it is easy to cause gas accumulation and the risk of gas explosion. Therefore, in general, to ensure safety, it is necessary to use an electric control valve with continuous ignition function and automatic gas shut-off to avoid the danger of gas explosion, but the price of the electric control valve is much higher than that of the manual ignition device.

Please refer to U.S. Patent No. D621873 "FIRE TORNADO LAMP", which discloses a seat body and a translucent cover. The peripheral ring of the seat body is provided with a plurality of air holes communicating with the inside of the transmissive cover, and the radial position of the air holes is inclined. The light transmissive cover is arranged in alignment, and the longitudinal position of the air hole is in an upright shape and is located in the body. When the outside air enters the interior of the transmissive cover via the obliquely aligned air holes, the air forms a swirling flow that provides the air required by the flame to allow the flame to continue to burn and form a rotating effect.

However, since the air inlet is located on the plane and above the combustion port, the direction of the air intake is perpendicular to the direction of combustion of the flame, and the rotating flame effect can only be formed when the flame scale is large enough. If the flame scale is small, it cannot be formed obviously and stably. Rotating flame effect. And only a small part of the externally inhaled cold air flows through the surface of the combustion device, causing the glass tube and the device to accumulate high temperatures. Also, since the bottom of the device is a closed end, and a semi-closed region is formed in the vicinity of the combustion head with the surrounding flow guiding passage and the glass, there is a problem that the gas is easily accumulated at the bottom as described above. In general, to ensure safety, an electronically controlled valve with continuous ignition and automatic shut-off of gas must be used to avoid the risk of gas explosion.

Please continue to refer to the patent application "Improvement of Combustion Device for Outdoor Flame Heater" of Chinese Patent No. M461769, which is a burner with a gas distribution chamber in the middle of the burner and a plurality of flame holes on the top surface and gas distribution. The periphery of the chamber forms a flange surface and can be coupled to the base; the upper cover of the burner has a cover body, and an air flow distribution chamber is defined between the cover body and the burner, and a plurality of air flow holes are arranged around the cover body, and the upper part is provided with a plurality of air flow holes a recessed mounting hole is provided for embedding the bottom end of the glass tube and located at the plurality Above the flame hole and the air distribution chamber, the gas is mixed with the air to form a fire-like fire net, which improves the combustion efficiency, so that the flame rises up to a better height in the glass tube by the chimney effect. According to to enhance the heating effect.

However, the burner having the above structure is provided with a glass tube above the gas distribution chamber for causing a chimney effect, and in order to allow air to enter the glass tube from below the glass tube, the cover and the burner must have an air flow distribution chamber. For the air to circulate, the burner is easily exposed to the wind when it is placed outdoors. When the burner is hit by the wind, the wind directly blows directly into the flame hole of the gas distribution chamber through the air distribution chamber, which easily affects the combustion conditions. With flame shape. In the case of combustion, the gas is injected into the tube by pressurized gas to increase the flame height. Due to the high injection velocity of the pressurized gas, it is not easy to control the ignition timing in the glass tube, and a turbulent flame is formed after the combustion, and only a small part of the externally sucked cold air flows through the surface of the combustion device, causing the glass tube and the device to accumulate high temperature. . Also, since the bottom of the device is a semi-closed end, a semi-closed region is formed near the combustion head with the surrounding air intake holes and the glass. If the ignition is not properly performed, after the gas supply starts, if the ignition time is too late or the first time after starting the gas supply, the high concentration gas may accumulate at the bottom of the device. If the user continues to manually supply the gas without knowing it. Continuous ignition may cause the local gas concentration to be too high and the risk of gas explosion. In general, to ensure safety, an electronically controlled valve with continuous ignition and automatic shut-off of gas must be used to avoid the risk of gas explosion. The price of the electronically controlled valve is much higher than that of the manual ignition device.

In view of the above-described deficiencies in the conventional structure, the inventors have invented a combustion apparatus which can stabilize the flame and which is still relatively safe in increasing the combustion scale, which overcomes all the disadvantages of the above-mentioned conventional structure.

Please refer to FIG. 5 and FIG. 6 for further use of the first embodiment of the present invention for improving the visibility of the flame and the safety of the gas burner. The intake head 23 can be connected to the gas tank 90 or the gas line by the user, and the gas can flow to the gas pipe 24 via the gas inlet pipe 23, and flows out through the gas outlet 245 of the gas pipe 24, via the two A concentrating piece 25 concentrates the gas into the flow guiding assembly 30 for the user to ignite and extends the gas in the planar direction, so that the combustion device 10 only needs to burn a small amount of gas to obtain a strong Visual effect.

When the combustion device 10 is blown by the external airflow, the flow guiding assembly 30 bears the brunt, and the airflow flows through the flow guiding assembly 30 to change direction, thereby avoiding the flame being blown by the airflow when the burning end 22 of the burner 20 is burned. And extinguished. After the airflow is blocked by the flow guiding component 30, part of the airflow will be turned, and part of the airflow will be from the bottom side of the first supporting member 31 and the second supporting member 32 and via the first guiding member 33 and the The gap between the second flow guiding members 34 flows into the interior of the flow guiding assembly 30, and the flow direction is turned to flow from bottom to top, rather than directly flowing to the flame to cause combustion instability.

In addition, since the combustion generates high heat and the air in the vicinity of the combustion end 22 of the burner 20 is heated and reduced in density, buoyancy is generated to cause the hot air to flow upward, so that the semi-closed region in the flow guiding assembly 30 is so-called a stack effect, and a negative pressure is generated on a side of the first flow guiding member 33 and the second flow guiding member 34 close to the burner 20, and the first supporting member 31 and The space on the bottom side of the second support member 32 is connected to the outside of the flow guiding assembly 30 to take in a fresh air flow. The first flow guiding member 33 and the second flow guiding member 34 form a stable air curtain between the flame and the combustion device 10, and the air curtain can effectively provide heat dissipation for the flow guiding assembly 30 of the combustion device 10. .

If the combustion scale becomes larger, the introduced airflow will be relatively adjusted due to the enhanced chimney effect, in addition to providing sufficient oxygen to complete the combustion reaction of the combustion device 10, and at the same time, the heat dissipation effect is enhanced. Since the direction of the airflow is not directly blown to the flame, not only does the combustion instability not occur, but the strength of the introduced airflow becomes stronger, thereby improving the stability of the flame, and greatly reducing the situation in which the combustion scale is increased to cause the flame to be unstable.

Since the first flow guiding member 33 and the second flow guiding member 34 can guide the airflow and change the direction on average, the airflow blown to the combustion device 10 can smoothly pass through the first flow guiding member 33 and the second flow guiding member. 34 a gap between each other forms a heat dissipation airflow, and the heat dissipation airflow has a heat dissipation effect, and the first flow guiding member 33 and the second flow guiding member 34 can conduct heat to the combustion device 10 due to heat generated by combustion. It is transmitted away from the direction of the burner 20. When the fresh air is introduced into the flow guiding assembly 30, the heat of the surface of the first flow guiding member 33 and the second flow guiding member 34 is taken away, because the first guiding member 33 and the second guiding member The large surface area of 34 is equivalent to an increase in the heat dissipating area, so that the temperature of the combustion apparatus 10 can be effectively prevented from being excessively high. When the heat-dissipating airflow continues to flow to the vicinity of the burner 20, the heat-dissipating airflow is heated by the flame of the burner 20 to generate a chimney effect, forming an ascending airflow, which can accelerate the flow of the air and avoid accumulation of hot air inside the combustion device 10, Greatly enhance the effect of heat dissipation.

Since the flow guiding assembly 30 further has the first deflector 35 and the second deflector 36, when the airflow flows into the flow guiding assembly 30, the airflow direction is turned from the bottom to the top, The first baffle 35 and the second baffle 36 are blown to prevent the airflow from directly hitting the combustion end 22 of the burner 20. And because the first baffle 35 is away from the side of the burner 20 toward the first support member 31 and extends upward in the direction of the plumb bob, the combustion of the airflow to the flame is further prevented from causing combustion instability.

The first air guiding plate 35 and the second air guiding piece 36 respectively pass through the first air guiding hole 351 and the second air guiding hole 361, the first air guiding hole 351 and the second air guiding flow. The hole 361 can supply airflow, ensure the smooth flow of the airflow and accelerate the flow of the air, avoid the accumulation of hot air inside the combustion device 10, greatly enhance the heat dissipation effect, and at the same time, the air flow speed is fast, and the gas rise after the volatilization can be quickly driven. .

Moreover, since the components of the flow guiding assembly 30 can be completed by sheet metal work, the parts of the flow guiding assembly 30 are made very easy, and the connection between the parts can be screwed to make the flow guiding assembly 30 Assembly work is very easy to accomplish.

Please refer to FIG. 7 to FIG. 9 for a perspective view and an exploded perspective view of a second embodiment of the gas combustion apparatus for improving flame visibility and safety according to the present invention. The second embodiment is substantially the same as the first embodiment. The main difference between the second embodiment and the first embodiment is that the horizontal section 242a of the air duct 24a extends in the curved direction in this embodiment. The horizontal section 242a of the air tube 24a is annular and the ends are opposite to each other. The number of the at least one first current collecting piece 25a is two in the embodiment, and the two ends of the two first current collecting pieces 25a are butted against each other. And in the form of an annular shape, the number of the at least one second current collecting piece 26a in the present embodiment is two, and both ends of the two second current collecting pieces 26a abut each other to form an annular shape.

The number of the at least one first support member 31a is two in the embodiment, the two ends of the two first support members 31a abut each other to form an annular shape, and the at least one second support member 32a is in the present embodiment. The number of the two second support members 32a is abutted to each other to form an annular shape, and the number of the at least one first baffle 35a in the embodiment is two, the two The two ends of the first baffle 35a abut each other to form an annular shape, the number of the at least one second baffle 36a in the embodiment is two, and the two of the two second baffles 36a The ends abut each other and form an annular shape.

The flow guiding assembly 30a having the structure of the present invention can be designed into various shapes according to the user's requirements, so that the flame generated by the combustion device 10a can exhibit various shapes, and the first current collecting piece 25a, the first The second current collecting piece 26a, the first supporting piece 31a, the second supporting piece 32a, the first guiding piece 35a and the second guiding piece 36a can be assembled by using a plurality of parts, so that the guiding component Even if the design is a complex shape, 30a does not increase the difficulty of processing during assembly or assembly.

As far as the above is concerned, it can be concluded that the present invention has the following advantages:
