Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of burners, and more specifically, to a three-ring burner structure for preventing dry burning. Background Technology
[0002] Currently, most existing anti-dry-burning stoves use the mature contact sensing technology of telescopic temperature sensors. The working principle is to contact the bottom of the pot with the telescopic temperature sensor so that the sensor can detect the temperature of the pot. When the temperature of the bottom of the pot exceeds the set normal operating temperature, the main control board determines that the pot has overheated due to dry burning.
[0003] However, existing telescopic temperature sensors are all installed inside the flame ring, and the upper part of the telescopic temperature sensor protrudes relative to the flame ring, making the telescopic temperature sensor susceptible to being burned by the flame. This causes the telescopic temperature sensor to heat up rapidly during use, leading to misjudgments. Moreover, since the telescopic temperature sensor is a contact detection type, its surface is easily oxidized after long-term burning, resulting in reduced thermal conductivity and malfunctions. Utility Model Content
[0004] In order to overcome the defects of the existing technology, this utility model provides a three-ring burner structure to prevent dry burning, so as to solve the problems in the existing technology.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a three-ring burner structure for preventing dry burning, including a base and a burner body mounted on the base. A telescopic temperature sensor that can be moved up and down is installed on the base. A fire ring is provided on the burner body. The telescopic temperature sensor is installed inside the fire ring. A heat insulation unit is provided on the fire ring. The heat insulation unit is arranged around the outer side of the upper part of the telescopic temperature sensor.
[0006] In the above-mentioned anti-dry-burning three-ring burner structure, the fire ring part includes an outer fire ring, an inner fire ring and a central fire ring. A secondary air supply hole is opened in the middle of the central fire ring. The upper part of the telescopic temperature sensor is inserted into the secondary air supply hole. The heat insulation unit is installed on the upper end face of the central fire ring.

The heat insulation ring is arranged around the outer side of the upper part of the telescopic temperature sensor, and at least one heat dissipation hole is provided at the lower end of the heat insulation ring.
[0008] In the aforementioned anti-dry-burning three-ring burner structure, the heat dissipation holes are strip-shaped holes.

[0012] The beneficial effects of this utility model are that by setting the telescopic temperature sensor inside the flame ring and having a heat insulation unit at the upper end of the flame ring, the heat insulation unit can surround the upper part of the telescopic temperature sensor. During the jet combustion process in the flame ring, the flame can be isolated by the heat insulation unit to prevent the flame from directly burning the telescopic temperature sensor and causing malfunction or damage.

Detailed Implementation
[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0019] Combination Figures 1 to 4 The illustrated anti-dry-burning three-ring burner structure includes a base 1 and a burner body 2 mounted on the base 1. A telescopic temperature sensor 6, which can be adjusted vertically, is installed on the base 1. The burner body 2 has a flame ring section, which includes an outer flame ring 3, an inner flame ring 4, and a central flame ring 5. The telescopic temperature sensor 6 is installed inside the central flame ring 5, and a heat insulation unit is provided on the central flame ring 5, surrounding the upper outer part of the telescopic temperature sensor 6. In this embodiment, by placing the telescopic temperature sensor 6 inside the central flame ring 5 and having a heat insulation unit at the upper end of the central flame ring 5, the heat insulation unit can surround the upper part of the telescopic temperature sensor 6. During the jet combustion process of the central flame ring 5, the flame can be isolated by the heat insulation unit, preventing the flame from directly burning the telescopic temperature sensor 6 and causing malfunction or damage. Moreover, it effectively improves the accuracy of detection and reduces the phenomenon of false judgment.
[0020] It is worth noting that the central fire ring 5 is provided with an inclined surface, and jet holes are opened on the inclined surface to spray out premixed gas for combustion, so that the flame forms a ring flame, and the ring flame is located on the outside of the heat insulation unit.
[0021] In this embodiment, a secondary air supply hole 7 is provided in the middle of the central fire ring 5. The upper part of the telescopic temperature sensor 6 is inserted into the secondary air supply hole 7, and the heat insulation unit is installed on the upper end face of the central fire ring 5. During the combustion process of the premixed gas sprayed out by the central fire ring 5, the secondary air supply hole 7 can supply air from bottom to top, so that the air first contacts the telescopic temperature sensor 6, thereby removing the heat on the telescopic temperature sensor 6, reducing the temperature of the telescopic temperature sensor 6, and preventing it from being exposed to high temperature for a long time, which would affect its service life.
[0022] Specifically, the heat insulation unit in this embodiment includes a heat insulation ring 8 installed on the upper end face of the central fire ring 5. The heat insulation ring 8 is arranged around the outer side of the upper part of the telescopic temperature sensor 6. Heat dissipation holes 9 are provided on both sides of the lower end of the heat insulation ring 8. This allows air to be output not only from the upper end but also from the heat dissipation holes 9 during the process of replenishing air through the secondary air replenishment hole 7, so that the heat in the secondary air replenishment hole 7 can be dissipated quickly, thereby reducing the temperature of the telescopic temperature sensor 6.
[0023] It is worth noting that the heat dissipation hole 9 in this embodiment is a strip-shaped hole, which has higher heat dissipation efficiency.
[0024] In some embodiments, the flame ring can be a single-ring flame ring, applied in a single-ring burner structure.
[0025] In this embodiment, a clearance hole is provided in the middle of the base 1. Positioning posts 10 are provided on both sides of the lower end of the clearance hole. A sensor mounting base 11 is sleeved on the positioning posts 10. The telescopic temperature sensor 6 is located in the clearance hole, and the lower part of the telescopic temperature sensor 6 passes through the sensor mounting base 11. The telescopic temperature sensor 6 can move up and down within the sensor mounting base 11. This allows the telescopic temperature sensor 6 to be installed on the sensor mounting base 11 through the clearance hole, and the telescopic temperature sensor 6 can move up and down within the sensor mounting base 11 to adjust its height to adapt to the bottom height of different cookware.
[0026] In this embodiment, the sensor mounting base 11 includes a mounting block 12. Sockets 13 are provided on both sides of the upper end of the mounting block 12. Each socket 13 has a corresponding insertion hole 14. A cover plate 17 is screwed onto one side of the mounting block 12. The lower end of the telescopic temperature sensor 6 is movably mounted between the mounting block 12 and the cover plate 17, allowing the telescopic temperature sensor 6 to be easily mounted on the base 1. A pipe 15 is provided inside the mounting block 12, containing multiple slots 16. The cover plate 17 has multiple corresponding holes 18. The lower end of the telescopic temperature sensor 6 passes through the pipe 15, and a protruding ring 19 is provided on the outer wall of the lower end of the telescopic temperature sensor 6. The protruding ring 19 engages between the holes 18 and slots 16, allowing the telescopic temperature sensor 6 to be fixed inside the pipe 15. Simultaneously, the cover plate 17 can be loosened to adjust the position of the protruding ring 19 between each hole 18 and slot 16, thereby adjusting the height of the telescopic temperature sensor 6.
[0027] It is worth noting that the telescopic temperature sensor 6 is existing technology and will not be described in detail here.
[0028] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
