Description

Technical Field

[0001] The utility model relates to the technical field of gas burner manufacturing, in particular to a burner with a large load and equipped with a sensor. Background Art

[0002] Gas burners are a type of combustion device that is widely used in various kitchen stoves. As the market demands for high-load burners, there is an urgent need to increase the load and improve the performance of existing products.

[0003] However, in practical applications, existing stove burners generally have the following defects:

[0004] 1. After the load is increased, the fire hole area is insufficient and the fire hole area needs to be increased, but the fire cover diameter cannot be increased.

[0005] 2. After the load increases, insufficient primary air will cause yellowing and other problems.

[0006] 3. The width of the fire hole of the fire cover is too narrow and difficult to process. The commonly used fire hole width is usually 1mm.

[0007] 4. The staggered arrangement of the upper and lower layers of fire holes will cause the upper and lower flames to cross when the width of the fire holes increases, resulting in poor combustion performance.

[0008] 5. The burner body ejector cannot meet the air demand after the load increases.

[0009] Therefore, how to solve the defects of insufficient fire hole area, difficult fire hole processing, and insufficient air injection of the burner after increasing the load has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0010] In view of the above-mentioned defects of the prior art, the utility model provides a burner with a large load and equipped with a sensor, the purpose of which is to solve the defects of insufficient fire hole area, difficult fire hole processing and insufficient air injection of the burner after the load is increased.

[0011] To achieve the above object, the utility model discloses a burner with a large load and capable of carrying a sensor, comprising a cylindrical fire cover and a burner body located below the fire cover;

[0012] The annular side wall of the fire cover is provided with a plurality of strip-shaped main fire holes;

[0013] Each of the main fire holes is a rectangular hole extending radially from a corresponding position of the annular side wall and penetrating the annular side wall;

[0014] The height of each of the main fire holes is 70% or 2 / 3 of the height of the annular side wall;

[0015] The ejector of the burner body is a variable cross-section tube, and includes an air intake contraction portion near the inlet of the burner body;

[0016] The outlet diameter of the air intake contraction portion is 1 / 3 to 1 / 2 of the inlet diameter;

[0017] The diameter of the connection between the ejector and the burner body is 1 to 1.5 times the outlet diameter of the air intake contraction portion;

[0018] A temperature sensor is provided in the middle of the fire cover, and the real-time temperature of the pot bottom during combustion is collected through the temperature sensor.

[0019] Preferably, the height of each of the main fire holes is between 5 mm and 7 mm, and the width perpendicular to the height is between 1.2 mm and 1.5 mm.

[0020] Preferably, the outlet diameter of the air suction contraction portion is 6.5 mm±10%, and the inlet diameter is 15 mm±10%.

[0021] Preferably, a mounting hole of 22 mm to 26 mm is provided in the middle of the fire cover, and the temperature sensor is arranged through the mounting hole.

[0022] Beneficial effects of the utility model:

[0023] After the area of ​​the fire hole of the utility model is increased, the height of the main fire hole of the fire cover is increased. In order to facilitate processing and production, the width of the fire hole is increased to make the airflow distribution more uniform.

[0024] The utility model improves the size of the air intake contraction part of the ejector, reduces the resistance when air enters, thereby increasing the air volume, improving the combustion performance, reducing the smoke, etc.

[0025] The utility model is equipped with a temperature sensor to solve the safety hazards caused by forgetting to turn off the fire and excessive oil temperature during actual use.

[0026] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 A structural schematic diagram of an embodiment of the utility model is shown. DETAILED DESCRIPTION

[0028] Example

[0029] like Figure 1 As shown, the burner with a large load and equipped with a sensor comprises a cylindrical fire cover 1 and a burner body 2 located at the lower part of the fire cover 1;

[0030] The annular side wall of the fire cover 1 is provided with a plurality of strip-shaped main fire holes 11;

[0031] Each main fire hole 11 is a rectangular hole extending radially from a corresponding position of the annular side wall and penetrating the annular side wall;

[0032] The height of each main fire hole 11 is 70% or 2 / 3 of the height of the annular side wall;

[0033] The ejector of the burner body 2 is a variable cross-section tube, and includes an air intake contraction portion 21 near the inlet of the burner body 2;

[0034] The outlet diameter of the air intake contraction 21 is 1 / 3 to 1 / 2 of the inlet diameter;

[0035] The diameter of the connection between the ejector and the burner body 2 is 1 to 1.5 times the outlet diameter of the air intake contraction portion 21;

[0036] A temperature sensor 3 is provided in the middle of the fire cover 1, and the temperature sensor 3 is used to collect the real-time temperature of the pot bottom during combustion.

[0037] In practical applications, since the diameter of the fire cover 1 cannot be changed, the height of the main fire hole 11 needs to be increased. However, simply increasing the height of the main fire hole 11 will cause the strip-shaped main fire hole 11 to be too long and easy to break, and is also difficult to manufacture.

[0038] Therefore, in order to ensure the area of ​​the main fire hole 11 and reduce the difficulty of processing, it is also necessary to increase the width of the main fire hole 11 to increase the strength of the main fire hole 11 to ensure that the main fire hole 11 of the product is not easily damaged.

[0039] Compared with the prior art, the main fire hole 11 of the utility model is wider and higher, which can ensure the area of ​​the main fire hole 11 and reduce the difficulty of processing, and the enlarged main fire hole 11 can increase the heat load.

[0040] The ejector of the burner body 2 adopts a variable cross-section tube, which can improve the single air ejection amount after the load is increased.

[0041] A temperature sensor 3 is provided in the middle of the fire cover 1, which can realize the function of automatically shutting down the fire when the oil temperature is too high during use.

[0042] In some embodiments, the height of each main fire hole 11 is between 5 mm and 7 mm, and the width perpendicular to the height is between 1.2 mm and 1.5 mm.

[0043] In practical applications, the size of the main fire hole 11 can meet the requirement of a maximum firepower of 5.2 kW.

[0044] In some embodiments, the outlet diameter of the suction constriction 21 is 6.5 mm±10%, and the inlet diameter is 15 mm±10%.

[0045] In practical applications, the variable cross-sectional size of the air intake contraction portion 21 of the burner body 2 can reduce the resistance loss when air enters and increase the single air injection amount.

[0046] In some embodiments, a mounting hole with a diameter of 22 mm to 26 mm is provided in the middle of the fire cover 1, and the temperature sensor 3 is arranged through the mounting hole.

[0047] In practical applications, a mounting hole of 22mm to 26mm works best. If the mounting hole is too large, it is easy for overflowing liquid to flow into the interior of the cooker and become difficult to clean. If the mounting hole is too small, it will not be conducive to the heat dissipation of the sensor and may cause malfunction.

[0048] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
