[Technical field]

[0001] The present application relates to the field of ovens, and in particular to a single-ejection tube burner head and a gas oven. [Background technology]

[0002] In the existing gas pizza oven, the gas burner head is generally in the shape of a long tube. In order to ensure the combustion uniformity and stability of the gas in the long tube gas burner head and prevent the flame separation phenomenon, a double ejector tube structure is generally used. However, the gas burner head with a double ejector tube will result in high cost, which is not conducive to controlling the overall cost of the gas oven and affects the market competitiveness of the product. Therefore, it is urgent to design a burner head with relatively low cost, stable combustion and no flame separation phenomenon. [Contents of the utility model]

[0003] In order to effectively reduce costs and ensure the combustion stability of the burner when gas is burned, the present application provides a single-ejector tube burner and a gas grill using the single-ejector tube burner.

[0007] In the single-ejector-tube furnace head as described above, the buffer zone is a cylindrical closed end located at one end of the air inlet pipe.

[0008] In the single-ejector-tube burner as described above, the air inlet pipe is located at the end of the gas main pipe.

[0009] As described above, in the single-ejector-tube type burner head, a furnace body assembly frame is provided at one end of the gas main pipe away from the air inlet pipe.

[0012] The present application also provides a gas grill, comprising a furnace body, on which the single-ejection tube type furnace head as described above is provided.

[0013] In the gas grill as described above, the gas main pipe is located outside the furnace body, and the ejector pipe is located outside the furnace body.

[0014] As described above, the gas oven has a baking area and a first fire baffle between the baking area and the gas main pipe in the oven body, and a second fire baffle above the gas main pipe in the oven body.

[0015] Compared with the prior art, this application has the following advantages:

[0016] The utility model discloses a single-injection-tube type burner head which only adopts a single injection tube to convey the mixed gas to the air inlet pipe, and has a simple structure and low cost.

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] When the embodiments of the present application mention ordinal numbers such as "first" and "second", unless they do express the meaning of order according to the context, they should be understood as being merely for the purpose of distinction.

[0023] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0024] Example: Figure 1 In the gas oven shown in the figure, the gas oven comprises an oven body 100, and the oven body 100 is provided with Figure 2 The single ejector tube type burner shown. The single ejector tube type burner comprises a gas main pipe 1 and an air inlet pipe 2 connected to the gas main pipe 1. In this embodiment, the gas main pipe 1 is in a straight tube shape. The shape of the gas main pipe 1 can also be an arc tube shape, as long as it can adapt to the shape of the furnace body 100; one end of the air inlet pipe 2 is connected to an ejector tube 3, and the other end of the air inlet pipe 2 is provided with a buffer zone 4 connected to the air inlet pipe 2. The connecting portion 5 between the gas main pipe 1 and the air inlet pipe 2 is located between the ejector tube 3 and the buffer zone 4. Furthermore, the gas main pipe 1 is located inside the furnace body 100, and the ejector tube 3 is located outside the furnace body 100. The single-injector-tube burner of this embodiment only uses a single injector tube 3 to convey the mixed gas to the air inlet pipe 2, which has a simple structure and low cost. Since the gas main pipe 1 is in the shape of a long tube, in order to ensure that the gas main pipe 1 has enough mixed gas, the injector tube 3 needs to convey the mixed gas with a relatively high pressure to the air inlet pipe 2 and the gas main pipe 1 to ensure that the gas main pipe 1 is completely covered with the mixed gas, so as to ensure the overall combustion uniformity of the gas main pipe 1. Meanwhile, by providing a buffer zone 4 at one end of the air inlet pipe 2, it can be ensured that when the injector tube 3 and the air inlet pipe 2 convey the high-pressure mixed gas to the gas main pipe 1, the position of the gas main pipe 1 near the air inlet pipe 2 will not have mixed gas with excessive pressure, thereby ensuring that the gas on the gas main pipe 1 will not have a flame-off phenomenon when burning, and ensuring the combustion uniformity and stability of the gas burner when burning.

[0025] Furthermore, the gas main pipe 1, the air intake pipe 2 and the ejector pipe 3 are integrally formed. The integrally formed design makes the connection between the gas main pipe 1, the air intake pipe 2 and the ejector pipe 3 tighter, reduces the risk of gas leakage and improves safety. At the same time, this structure is more stable when subjected to gas pressure and is not prone to deformation or damage.

[0026] Furthermore, the buffer zone 4 is a cylindrical closed end located at one end of the intake pipe 2. The cylindrical closed end provides a stable space for the mixed airflow. When the gas and air are mixed in the ejector pipe 3 and enter the buffer zone, the airflow will slow down due to the expansion of the space, thus becoming more stable. This helps to ensure the stability and uniformity of the gas during the combustion process.

[0027] Furthermore, the air inlet pipe 2 is located at the end of the gas main pipe 1. By directly arranging the air inlet pipe 2 at the end of the gas main pipe 1, the entire burner structure can be made more compact and the occupied space can be reduced, which is beneficial to optimizing the overall volume of the gas oven and making it easier to make it lighter.

[0028] Furthermore, in order to conveniently fix the gas main pipe 1 in the furnace body 100, a furnace body assembly rack 6 is provided at one end of the gas main pipe 1 away from the air inlet pipe 2. The furnace body assembly rack 6 provides a mounting and fixing position for the gas furnace body, so that the gas burner head can be stably installed at a desired position. This structure greatly simplifies the installation process, improves the installation efficiency, and ensures the stability of the gas burner head during use.

[0029] Furthermore, the gas main pipe 1 is provided with a gas outlet group 11 distributed along the length direction of the gas main pipe 1. By distributing the gas outlet group 11 along the length direction of the gas main pipe 1, it is possible to ensure uniform distribution of the gas in the combustion area. This uniform distribution helps to achieve more stable and efficient combustion, thereby improving combustion efficiency and reducing gas waste. Preferably, the gas main pipe 1 is provided with a plurality of rows of gas outlet groups 11, and the plurality of rows of gas outlet groups 11 are distributed at intervals along the circumference of the gas main pipe 1.

[0030] Furthermore, if Figure 3 As shown, a baking area 101 and a first fire baffle 102 located between the baking area 101 and the gas main pipe 1 are provided in the furnace body 100, and a second fire baffle 103 located above the gas main pipe 1 is provided in the furnace body 100. The first fire baffle 102 is located between the baking area 101 and the gas main pipe 1, and can effectively adjust the direction and distribution of the flame to ensure that the baking area 101 obtains evenly distributed heat. This even heat distribution helps to improve the baking effect, so that the food can be evenly heated, and avoid local overheating or under-baking.

[0031] The working principle of this embodiment is as follows:

[0032] The single-injector-tube burner of this embodiment only uses a single injector tube 3 to convey the mixed gas to the air inlet pipe 2, which has a simple structure and low cost. Since the gas main pipe 1 is in the shape of a long tube, in order to ensure that the gas main pipe 1 has enough mixed gas, the injector tube 3 needs to convey the mixed gas with a relatively high pressure to the air inlet pipe 2 and the gas main pipe 1 to ensure that the gas main pipe 1 is completely covered with the mixed gas, so as to ensure the overall combustion uniformity of the gas main pipe 1. Meanwhile, by providing a buffer zone 4 at one end of the air inlet pipe 2, it can be ensured that when the injector tube 3 and the air inlet pipe 2 convey the high-pressure mixed gas to the gas main pipe 1, the position of the gas main pipe 1 near the air inlet pipe 2 will not have mixed gas with excessive pressure, thereby ensuring that the gas on the gas main pipe 1 will not have a flame-off phenomenon when burning, and ensuring the combustion uniformity and stability of the gas burner when burning.

[0033] As described above, multiple implementation methods are provided in combination with specific contents, and the specific implementation of this embodiment is not limited to these descriptions. Any method, structure, etc. similar to or identical to this embodiment, or some technical deductions or replacements made based on the concept of this embodiment, shall be considered as the protection scope of this embodiment.
