Description

Technical Field

[0001] This utility model relates to the field of gas stove technology, and in particular to a burner assembly for a gas stove. Background Technology

[0002] Currently, gas stoves are widely used. Their main working principle is to guide gas through a gas pipe to the burner head of the stove, where it mixes with air to form a combustible mixture, which is then ignited. The burner cap, which covers the burner head, then guides the gas to burn evenly, resulting in a uniform flame.

[0003] However, after the gas is introduced into the burner ring of the furnace base, the gap between the burner ring and the furnace base is relatively large, and the combustible gas often overflows through the gap, causing the flame on the burner ring to backfire.

[0004] In addition, a certain amount of air needs to be mixed in during the gas introduction process to achieve complete combustion. Since the burner base is usually installed at the bottom of the gas stove, the air introduction channel is also usually set at the bottom. This can easily lead to insufficient air supply, resulting in incomplete combustion. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a burner assembly and a gas stove, which can be provided with a gas guide chamber and an air inlet channel on the burner base. The gas guide chamber can introduce air from the side to achieve gas mixing, thereby increasing the amount of air mixed in. After mixing, the gas is directly guided to the burner cap for combustion through the air inlet channel, thereby improving combustion efficiency.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A burner assembly for a gas stove, comprising,

[0008] A furnace base is provided with a gas guiding chamber and an air inlet channel. A gas inlet is provided on the side of the furnace base and is connected to the side of the gas guiding chamber. An air inlet is provided at the top of the gas guiding chamber and is connected to the top side of the furnace base. One end of the air inlet channel is formed as an air inlet end communicating with the gas guiding chamber, and the other end of the air inlet channel is formed as an air outlet end.

[0009] A fire cover, which is placed on top of the furnace base.

[0010] Furthermore, the air inlet is connected to the top of the furnace base; the furnace base is provided with a first air guide baffle, which surrounds the outer periphery of the air inlet, and the side of the first air guide baffle is provided with an air guide notch, which is connected to the air inlet.

[0011] Furthermore, the gas guide notch and the gas inlet are located on the same side of the furnace base and are distributed vertically.

[0012] Furthermore, the first gas guide baffle includes a first wall segment and two second wall segments, one end of the two second wall segments is connected to the first wall segment, and the other end of the two second wall segments extends to the outer periphery of the furnace base and is spaced apart to form the gas guide gaps.

[0013] Furthermore, the second wall segment is inclined towards the first wall segment from the outside in.

[0014] Furthermore, a second gas guide baffle is provided at the bottom end of the fire cover, which is used to abut against the first gas guide baffle after the fire cover is sealed to the top of the furnace base.

[0015] Furthermore, the gas guiding chamber includes two gas guiding end walls and two gas guiding side walls, one of the gas guiding side walls being connected to one end of the two gas guiding end walls, and the other gas guiding side wall being connected to the other end of the two gas guiding end walls; the gas inlet is connected to one of the gas guiding side walls, and the gas inlet is connected to the other gas guiding side wall.

[0016] Furthermore, the air guide end wall gradually slopes from the outside to the inside.

[0017] Furthermore, the distance between the two air-guiding sidewalls is D, and the value of D ranges from 18mm to 30mm.

[0018] A gas stove, including the aforementioned burner assembly.

[0019] In summary, this utility model has the following technical effects:

[0020] 1. Insert the burner base into the gas panel mounting position through the bottom of the gas stove. The burner base structure is located below the gas panel. The top cover of the burner base passes through the gas panel and covers the burner cap. Since the gas inlet of the burner base is located on the side of the burner base, the gas pipe can be connected to the gas guide chamber through the side of the burner base, making it convenient for users to connect the pipe from the side of the gas stove.

[0021] 2. Since the air inlet of the gas guide chamber runs through the side of the burner base, the air enters the gas guide chamber from the side of the burner base. This means that the amount of air supplied is less than if it is supplied from the bottom of the gas stove or other locations. The installation is more flexible and the requirements for the cabinet are lower. Even if the space at the bottom of the cabinet is limited or the sealing is good, air can still be supplied from the side, which reduces the possibility of the combustion effect being affected by unreasonable cabinet design.

Detailed Implementation

[0027] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] See Figures 1-4 This utility model discloses a burner assembly for a gas stove, including a burner base 10 and a burner cap 20. The burner base 10 has a gas guide chamber 11 and an air inlet channel. A gas inlet 12 is provided on the side of the burner base 10, and the gas inlet 12 communicates with the side of the gas guide chamber 11. Additionally, an air inlet 111 is provided at the top of the gas guide chamber 11, and the air inlet 111 connects to the top side of the burner base 10.

[0031] Specifically, one end of the air intake channel is formed as an air intake end 14 that communicates with the air guide chamber 11, and the other end of the air intake channel is formed as an air outlet end. The burner cap 20 is placed on the top of the furnace base 10, and the air outlet end guides the combustible gas to the position of the burner cap 20 for combustion.

[0032] Based on the above structure, when using the burner assembly of the gas stove of this utility model, the burner base 10 is inserted into the installation position of the gas panel through the bottom end of the gas stove. The structure of the burner base 10 is located below the gas panel. The top cover of the burner base 10 extends through the gas panel and covers the burner cap 20. Since the gas inlet 12 of the burner base 10 is located on the side of the burner base 10, the gas pipe can be connected to the gas guide chamber 11 through the side of the burner base 10, which is convenient for the user to connect the pipe from the side of the gas stove.

[0033] Since gas stoves in the current technology are generally installed in cabinets, if the air inlet of the burner base 10 is set at the bottom, the bottom of the cabinet needs to have enough space and ventilation to ensure that air can enter smoothly. However, if the cabinet is well sealed or the space is narrow, it will affect the air intake effect, resulting in incomplete combustion and the production of harmful gases such as carbon monoxide.

[0034] Therefore, in this embodiment, since the air inlet 111 of the air guide chamber 11 passes through the side of the stove base 10, the air enters the air guide chamber 11 of the stove base 10 from the side of the stove base 10. This means that the amount of air supplied is less than that supplied from the bottom of the gas stove or other locations. The installation is more flexible and the requirements for the cabinet are lower. Even if the space at the bottom of the cabinet is limited or the sealing is good, air can still be supplied from the side, which reduces the impact of unreasonable cabinet design on the combustion effect to a certain extent.

[0035] In use, gas is introduced into the gas inlet 12 through the gas pipe so that the gas enters the gas guide chamber 11. At the same time, after the gas enters the gas guide chamber 11, air can be added through the air inlet 111. In the gas guide chamber 11, the air and gas are fully mixed. Then, the gas enters the air intake channel through the air intake end 14 and is discharged to the burner cap 20 through the gas outlet end for combustion. In this way, the flame of the burner cap 20 burns fully and stably.

[0036] Furthermore, the aforementioned air inlet 111 is connected to the top of the furnace base 10, meaning that during processing, the air guide cavity 11 is directly connected to the end face of the furnace base 10, making processing easier and lower in cost.

[0037] After the air inlet 111 of the air guide cavity 11 extends to the top of the furnace base 10, since the air needs to be introduced from the side of the furnace base 10, a first air guide baffle 13 is provided on the furnace base 10. The first air guide baffle 13 surrounds the outer periphery of the air inlet 111, and the side of the first air guide baffle 13 is provided with an air guide notch 131, which is connected to the air inlet 111.

[0038] After assembly, when the burner cap 20 is installed on the furnace base 10, the bottom end of the burner cap 20 can abut against the first gas guide baffle 13. In this way, the top of the air inlet 111 is blocked by the burner cap 20, and the gas guide gap 131 of the first gas guide baffle 13 can be filled with air into the air inlet 111, and then into the gas guide chamber 11 to mix with the gas introduced by the gas inlet 12. This ensures that the amount of air supplied enters through the gas guide gap 131, preventing the gas concentration from being too low due to excessive air supply, which could lead to unstable combustion such as flame flickering, flashing, or even extinguishing.

[0039] Specifically, in order to allow air to be introduced from the side, the burner cap 20 is sealed to the top of the furnace base 10, which can also form an introduction interval around the periphery of the air guide cavity 11. However, this situation will lead to an excessive amount of air introduced, resulting in unstable combustion. At the same time, the gas introduced by the gas inlet 12 will also leak from the air inlet 111 of the air guide cavity 11, resulting in backfire. Therefore, the first air guide baffle 13 is set to partially surround the air inlet 111 of the air guide cavity 11, and air can be supplemented from the side through a single air guide gap 131.

[0040] Of course, if the air inlet 111 is not provided with the first air guide baffle 13, the top of the air guide cavity 11 can be set as a blind end, and the air inlet 111 can be provided on the side of the top of the air guide cavity 11.

[0041] Furthermore, the gas guide gap 131 and the gas inlet 12 are located on the same side of the furnace base 10 and are distributed vertically. In this way, the gas and air are both introduced on the same side of the gas guide chamber 11, and the introduction paths are relatively consistent. This makes it convenient for the gas to be fully mixed after introduction before entering the air inlet end 14 of the air inlet channel, so that the combustible gas is fully mixed and burned, resulting in more complete combustion.

[0042] Furthermore, in this embodiment, the first gas guide baffle 13 includes a first wall section 132 and two second wall sections 133. One end of the two second wall sections 133 is connected to the first wall section 132, and the other end of the two second wall sections 133 extends to the outer periphery of the furnace base 10 and is spaced to form gas guide gaps 131. In this way, the first gas guide baffle 13 can form a three-directional baffle structure from one first wall section 132 and two second wall sections 133. Air can be replenished by entering through the gas guide gaps 131, thus forming a stable air inlet flow direction and reducing gas leakage.

[0043] Furthermore, the second wall section 133 is inclined towards the first wall section 132 from the outside in, so that the gap between the two second wall sections 133 gradually narrows from the outside in. When air is introduced, the air can flow through the two second wall sections 133. The air can be introduced through the large gap in the air guide, and then gradually narrows after entering, so that the narrowed air can be squeezed downwards after the air is introduced, and fully mixed with the gas. Since the gas is below the air guide chamber 11, the space between the two second wall sections 133 on the inner side is small, and the air is introduced from above. This can effectively prevent the gas from leaking out from the upper air guide gap 131.

[0044] Furthermore, a second gas guide baffle 21 can be provided at the bottom of the burner cap 20. The second gas guide baffle 21 is used to abut against the first gas guide baffle 13 after the burner cap 20 is sealed to the top of the furnace base 10. When the burner cap 20 is sealed to the top of the furnace base 10, the second gas guide baffle 21 protruding from the bottom of the burner cap 20 abuts against the first gas guide baffle 13 protruding from the top of the furnace base 10. In this way, the air replenishment space formed at the air inlet 111 is formed by the upper and lower second gas guide baffles 21 and the first gas guide baffle 13. The air replenishment interval formed in this way is relatively large. Compared with the air replenishment interval formed by directly surrounding the first gas guide baffle 13, the air replenishment volume is larger, so it mixes more fully with the fuel gas and the combustion is more complete.

[0045] Furthermore, the aforementioned gas guiding chamber 11 includes two gas guiding end walls 113 and two gas guiding side walls 112. One gas guiding side wall 112 is connected to one end of the two gas guiding end walls 113, and the other gas guiding side wall 112 is connected to the other end of the two gas guiding end walls 113. The gas inlet 12 is connected to one of the gas guiding side walls 112, and the gas inlet 14 is connected to the other gas guiding side wall 112. Thus, when gas is introduced into the gas inlet 12, the gas is introduced through one gas guiding side wall 112 and then guided through the two gas guiding end walls 113 to the gas inlet 14 of the other gas guiding side wall 112. Since the gas is guided by the wall surface, the gas flow rate is stable, and the gas flowing on the wall surface can be fully mixed with air before entering the gas inlet 14, thus making the gas mixing more thorough.

[0046] Similarly, the gas guide end wall 113 gradually slopes from the outside inwards. After the gas enters through the gas inlet 12, the gas flows through the two gas guide end walls 113. Since the two gas guide end walls 113 gradually slope from the outside inwards, the gas gradually narrows towards the intake end 14 during the introduction process. At the relatively outer position of the two gas guide end walls 113, it can be fully mixed with air. After mixing, it gradually narrows and concentrates at the intake end 14 of the intake channel. The combustible gas enters the intake channel in a concentrated manner, reducing leakage.

[0047] Furthermore, the distance between the two air guide sidewalls 112 is D, and the value of D ranges from 18mm to 30mm. Within this range, the cavity space formed by the inner diameter of the air guide chamber is relatively reasonable, and the gas and air can be fully mixed before entering the air intake end, while the amount of air mixed in will not be too large.

[0048] Example 2,

[0049] A gas stove includes the burner assembly of Embodiment 1. The burner assembly is installed on the stovetop of the gas stove. Specifically, during assembly, the burner base 10 is inserted through the bottom of the gas stove into the mounting position of the gas panel. The structure of the burner base 10 is located below the gas panel. The top cover of the burner base 10 extends through the gas panel and covers the burner cap 20. Since the gas inlet 12 of the burner base 10 is located on the side of the burner base 10, the gas pipe can be introduced into the gas guide chamber 11 through the side of the burner base 10, making it convenient for the user to connect the pipe from the side of the gas stove.

[0050] Since gas stoves in the current technology are generally installed in cabinets, if the air inlet of the burner base 10 is set at the bottom, the bottom of the cabinet needs to have enough space and ventilation to ensure that air can enter smoothly. However, if the cabinet is well sealed or the space is narrow, it will affect the air intake effect, resulting in incomplete combustion and the production of harmful gases such as carbon monoxide.

[0051] Therefore, in this embodiment, since the air inlet 111 of the air guide chamber 11 passes through the side of the stove base 10, the air enters the air guide chamber 11 of the stove base 10 from the side of the stove base 10. This means that the amount of air supplied is less than that supplied from the bottom of the gas stove or other locations. The installation is more flexible and the requirements for the cabinet are lower. Even if the space at the bottom of the cabinet is limited or the sealing is good, air can still be supplied from the side, which reduces the impact of unreasonable cabinet design on the combustion effect to a certain extent.

[0052] In use, gas is introduced into the gas inlet 12 through the gas pipe so that the gas enters the gas guide chamber 11. At the same time, after the gas enters the gas guide chamber 11, air can be added through the air inlet 111. In the gas guide chamber 11, the air and gas are fully mixed. Then, the gas enters the air intake channel through the air intake end 14 and is discharged to the burner cap 20 through the gas outlet end for combustion. In this way, the flame of the burner cap 20 burns fully and stably.

[0053] Of course, it should be noted that the other structures of the burner assembly in this embodiment are the same as those in Embodiment 1, and the other structures of the gas stove are all existing technologies. The gas ignition structure and working principle are the same as those of existing technologies, and will not be described in detail here.

[0054] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
