The length L of 4 is greater than the width W of the main flame holes 4 , so that the main flame holes 4 are formed in a long and narrow shape (strip shape) along the transverse width direction B. As shown in FIG.

The top plate 12 is divided into a middle part C and two end parts D along the longitudinal direction A. The two end parts D are respectively located at opposite ends of the middle part C, and the main flame holes 4 are distributed in the middle part C of the top plate 12. and edge part D. The width W of the main flame holes 4 disposed at the edge portion D of the top plate 12 is relatively small, that is, the width W of the main flame holes 4 disposed at the edge portion D of the top plate 12 can be appropriately reduced. The width W of the main flame holes 4 at the edge portion D of the top plate 12 is preferably 0.5 mm to 0.65 mm to form an optimal size. The width W of the main flame holes 4 arranged in the middle portion C of the top plate 12 is relatively large, and the width W of the main flame holes 4 arranged in the middle portion C of the top plate 12 is preferably more than 0.65 mm, so that the The width W of the main flame holes 4 at the edge portion D of the top plate 12 is smaller than the width W of the main flame holes 4 arranged at the middle portion C of the top plate 12 . Preferably, the number of the main flame holes 4 disposed on each edge portion D of the top plate 12 is 2 to 6, such as 2, 3, 4, 5 or 6, which can be used to Better thermal insulation.

Since the width W of the main flame holes 4 disposed at the edge portion D of the top plate 12 is smaller than the width W of the main flame holes 4 disposed at the middle portion C of the top plate 12, this will make the main flame holes 4 disposed in the top plate 12 The flames generated by the main flame holes 4 at the edge portion D are smaller, that is, the flames generated by the main flame holes 4 near the two ends of the burner are smaller.

The gas channel 2 communicates with the gas inlet 3 and the main flame holes 4 , that is, one end of the gas channel 2 communicates with the gas inlet 3 , and the other end of the gas channel 2 communicates with the main flame holes 4 . The gas can be fed through the gas inlet 3, mixed with air, and then passed through the main flame holes 4 to generate flames. The gas is first mixed with the air at the gas inlet 3, and the incompletely burned gas is then added to the flame. The main flame holes 4 are mixed with air for the second time.

In addition, the burner body 1 can also be provided with two auxiliary flame holes 5, the two auxiliary flame holes 5 are located on both sides of the top plate 12, the two auxiliary flame holes 5 are long and narrow, and the two auxiliary flame holes 5 are along the longitudinal direction. A extends. In this embodiment, the two side plates 11 of the burner body 1 are connected to a flame shield 13 near the upper end respectively. The two flame shield plates 13 are located on the outer sides of the two side plates 11 respectively, and the two auxiliary flame holes 5 are formed on the two side plates 11. Between the two flame shielding plates 13 , that is, the outer side of each side plate 11 is correspondingly provided with a flame shielding plate 13 , and an auxiliary flame hole 5 is formed between each side plate 11 and the outer flame shielding plate 13 . The gas channel 2 is connected to the gas inlet 3 and the two auxiliary flame holes 5, that is, the other end of the gas channel 2 is also connected to the two auxiliary flame holes 5. The other ends of the gas channel 2 can pass through the two side plates respectively. The through hole 14 on the 11 communicates with the two auxiliary flame holes 5 . The gas can be fed through the gas inlet 3, mixed with air, and then passed through the two auxiliary flame holes 5 to generate a flame, and the flame formed on the auxiliary flame holes 5 can be used to provide ignition effect and remain formed on the main flame hole 4. the main flame. In this embodiment, a reinforcing rib 15 is provided on each of the two flame protection plates 13 near the upper end. The two reinforcing ribs 15 each have an inner surface 151 and an outer surface 152 (as shown in FIG. 5 ). 151 and the outer surface 152 both extend outward and protrude out of the flame protection plate 13 , and the inner surface 151 and the outer surface 152 can be concave arc surfaces and convex arc surfaces, respectively. The two reinforcing ribs 15 respectively protrude from the outer sides of the two flame-preserving plates 13 , and the two reinforcing ribs 15 extend horizontally for a predetermined length, which can be used to increase the strength of the two flame-preserving plates 13 .

The burners can be combined side by side to form a burning device. The burning device can be installed in a casing 6 (as shown in Fig. 6 and Fig. 7 ) so as to be installed in a gas water heater. It is arranged below the water tank so as to use the burning device to heat the water in the water tank, so as to generate hot water for consumers to use.

[Advantageous effects of the embodiment]

The beneficial effect of the present invention is that the burner for a gas water heater provided by the present invention includes a burner body, a gas channel, a gas inlet and a plurality of main flame holes. The top plate of the burner body is divided into a middle part and two end parts along the longitudinal direction, the main flame holes are distributed in the middle part and the edge parts of the top plate, and the main flame holes are arranged at the edge parts of the top plate.
