Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a burner and a gas water heater. Background Art

[0002] At present, gas water heater refers to a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water.

[0003] In the operation of the burner of the gas water heater, it is usually necessary to add secondary air at the bottom of the burner fire grate. The secondary air flows from between the two fire grate sheets to the top of the burner fire grate to provide the oxygen required for combustion, and can also promote the combustion process and improve the combustion efficiency. Since the gap between the burner fire grate sheets cannot be guaranteed to be consistent during assembly, the secondary air intake resistance of each part of the burner fire grate is inconsistent, which makes the combustion thermal efficiency of each part of the burner fire grate inconsistent. Therefore, the existing practice is to set a distribution plate for secondary air distribution at the bottom of the burner, and set air intake holes of different sizes or shapes at different parts of the distribution plate to balance the secondary air intake resistance of each part of the burner fire grate, so as to achieve uniform and stable combustion thermal efficiency of each part of the burner fire grate. However, when installing the distribution plate, it is necessary to screw and install multiple screws separately, which is cumbersome and time-consuming. When the distribution plate needs to be disassembled, replaced or maintained, the screws need to be loosened again, which makes the disassembly and assembly of the distribution plate inconvenient and the disassembly and assembly efficiency is low.

[0037] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0038] In the burner of the gas water heater, a sheet metal part, namely the secondary air distribution plate, is installed at the bottom of the fire bar by screws. When installing the distribution plate, multiple screws need to be screwed and installed separately, which is cumbersome and time-consuming. When the distribution plate needs to be disassembled, replaced or maintained, the screws need to be loosened again, making the disassembly and assembly of the distribution plate inconvenient and low in efficiency.

[0039] To solve the above problems, Figure 1 to Figure 4 As shown, this embodiment proposes a burner, which includes a fire bar 1 and a distribution plate 2. The first mounting plate 11 and the second mounting plate 12 are fixedly mounted on opposite sides of the fire bar 1, respectively. The first mounting plate 11 is provided with a first clamping portion 111, and the second mounting plate 12 is provided with a second clamping portion 121. The distribution plate 2 is provided with an air inlet 20 and is covered on the bottom of the fire bar 1 to distribute secondary air. The third clamping portion 21 and the fourth clamping portion 22 are respectively provided on opposite sides of the distribution plate 2. The third clamping portion 21 is clamped and matched with the first clamping portion 111, and the fourth clamping portion 22 is clamped and matched with the second clamping portion 121, so that the distribution plate 2 is fixedly mounted on the bottom of the fire bar 1. When the distribution plate 2 is installed at the bottom of the fire bar 1, the distribution plate 2 is fixedly installed on the fire bar 1 through the snap-fitting of the first snap-fitting portion 111 and the third snap-fitting portion 21 as well as the snap-fitting of the second snap-fitting portion 121 and the fourth snap-fitting portion 22. The distribution plate 2 can be quickly installed without using fasteners such as screws, and it is convenient to quickly remove the distribution plate 2 from the fire bar 1, making the disassembly and assembly operation of the distribution plate 2 simple and easy, reducing the disassembly and assembly time and workload of the distribution plate 2, and improving the disassembly and assembly efficiency of the distribution plate 2.

[0040] Specifically, a first mounting plate 11 is provided at the front side of the bottom of the fire bar 1, and a second mounting plate 12 is provided at the rear side of the bottom of the fire bar 1. A third clamping portion 21 is provided at the front end of the distribution plate 2, and a fourth clamping portion 22 is provided at the rear end of the distribution plate 2. First, the first clamping portion 111 is clamped and matched with the third clamping portion 21 to clamp and install the front end of the distribution plate 2 on the front end of the fire bar 1, and then the rear end of the distribution plate 2 is pressed so that the fourth clamping portion 22 is clamped and matched with the second clamping portion 121 to clamp and install the rear end of the distribution plate 2 on the rear end of the fire bar 1, thereby realizing the clamping installation of the distribution plate 2 on the fire bar 1.

[0041] like Figure 1 and Figure 2As shown, at least two first clamping parts 111 are arranged at intervals on one side of the bottom end of the first mounting plate 11, and at least two third clamping parts 21 are arranged at intervals on the distribution plate 2, and the first clamping parts 111 and the third clamping parts 21 are clamped and matched one by one. At least two second clamping parts 121 are arranged at intervals on the second mounting plate 12, and at least two fourth clamping parts 22 are arranged at intervals on the distribution plate 2, and the fourth clamping parts 22 and the second clamping parts 121 are clamped and matched one by one. By providing multiple groups of first clamping parts 111 and third clamping parts 21 that are clamped and matched, the stability of the front end installation of the distribution plate 2 is improved. At the same time, by providing multiple groups of fourth clamping parts 22 and second clamping parts 121 that are clamped and matched, the stability of the rear end installation of the distribution plate 2 is improved, thereby achieving reliable installation of the distribution plate 2 and avoiding the circumferential edge of the distribution plate 2 from warping.

[0042] Specifically, in this embodiment, there are two first clamping parts 111 and two second clamping parts 121, and the first clamping parts 111 and the second clamping parts 121 are arranged opposite to each other. In other embodiments, the number and position of the first clamping parts 111 and the second clamping parts 121 can be flexibly adjusted, which is not specifically limited here.

[0043] In an optional embodiment, the first clamping portion 111 is a clamping arm, the third clamping portion 21 is a clamping slot, and the clamping arm is clamped in the clamping slot. In another optional embodiment, the first clamping portion 111 is a clamping slot, and the third clamping portion 21 is a clamping arm. Specifically, Figure 3 As shown, the first clamping portion 111 includes a curved portion 1111 and a horizontal portion 1112, and the first mounting plate 11 is extended to be provided with the curved portion 1111, and the curved portion 1111 is clamped in the clamping slot. The horizontal portion 1112 is connected to the curved portion 1111 and pressed against the lower surface of the distribution plate 2. The first clamping portion 111 of this embodiment is an L-shaped snap arm, and the front end of the distribution plate 2 is clamped and installed in the groove body surrounded by the first clamping portion 111 and the first mounting plate 11. The curved portion 1111 is clamped in the clamping slot to limit the front end of the distribution plate 2 in the left and right directions. At the same time, the horizontal portion 1112 presses the distribution plate 2 against the bottom of the fire bar 1 to limit the front end of the distribution plate 2 in the up and down directions, so as to ensure that the front end of the distribution plate 2 is reliably installed, avoid positional displacement, and improve the installation accuracy of the distribution plate 2.

[0044] Specifically, the card slot penetrates the front end of the distribution plate 2 to form an opening, and the snap arm is slidably snapped into the card slot through the opening. When the distribution plate 2 is installed, first align the opening of the third snap-fitting portion 21 with the corresponding first snap-fitting portion 111, and then push the distribution plate 2 from the back to the front, so that the bent portion 1111 slides from the opening into the third snap-fitting portion 21, and the front end of the distribution plate 2 can be installed, making the installation operation simple and efficient.

[0045] like Figure 4As shown, the distribution plate 2 is further provided with a fifth clamping portion 23, and the fifth clamping portion 23 is clamped and matched with the second mounting plate 12. Through the above arrangement, the connection strength and stability between the rear end of the distribution plate 2 and the second mounting plate 12 are further improved.

[0046] In one embodiment, if Figure 4 and Figure 5 As shown, the fifth clamping portion 23 includes a first side plate 231, a bending portion 232 and a second side plate 233. The top end of the first side plate 231 is connected to the distribution plate 2. The bottom end of the first side plate 231, the bending portion 232 and the second side plate 233 are sequentially connected to form a U-shaped bend with the opening facing upward, and the second mounting plate 12 is clamped in the U-shaped bend. The first side plate 231 and the second side plate 233 of the U-shaped bend are spaced apart in the left-right direction, so that when the second mounting plate 12 is clamped and matched with the U-shaped bend, the distribution plate 2 can be installed in a limited position in the left-right direction.

[0047] Furthermore, the width of the U-shaped bend is h, and the thickness of the second mounting plate 12 is H, then 0.8≤h / H<1. Since the width of the U-shaped bend is slightly smaller than the thickness of the second mounting plate 12, that is, the distance between the first side plate 231 and the second side plate 233 is slightly smaller than the thickness of the second mounting plate 12, the first side plate 231 and the second side plate 233 can clamp the second mounting plate 12, thereby achieving stable installation of the second mounting plate 12 and the U-shaped bend, and further enhancing the installation strength of the rear end of the distribution plate 2 and the second mounting plate 12.

[0048] like Figure 5 As shown, one of the first side plate 231 and the second side plate 233 is provided with a fourth clamping portion 22 toward the inside of the U-shaped bend, and the other of the first side plate 231 and the second side plate 233 is provided with a avoidance hole 2311 directly opposite to the fourth clamping portion 22. The second clamping portion 121 of this embodiment is a positioning hole, and the fourth clamping portion 22 is clamped in the positioning hole. Further, the projection area of ​​the avoidance hole 2311 on the second mounting plate 12 is larger than the opening area of ​​the positioning hole. Since the second clamping portion 121 is located inside the U-shaped bend, the size of the distribution plate 2 along the front-to-back direction is reduced, and the compactness of the structure of the distribution plate 2 is improved. By providing the avoidance hole 2311, the fourth clamping portion 22 can be prevented from interfering with the first side plate 231, so that the fourth clamping portion 22 has a sufficient length, so that the fourth clamping portion 22 can be stably clamped in the positioning hole, and the fourth clamping portion 22 with too short a length can be prevented from escaping from the positioning hole.

[0049] In one embodiment, the second clamping portion 121 is one of a convex bulge and a positioning hole, and the fourth clamping portion 22 is the other of the convex bulge and the positioning hole, and the convex bulge is clamped in the positioning hole. In this embodiment, the second clamping portion 121 is a positioning hole, and the fourth clamping portion 22 is a convex bulge. Specifically, Figure 4 and Figure 5 As shown, the fourth clamping portion 22 is a convex bump, and a convex bump is integrally formed on the second side plate 233. By punching the convex bump on the second side plate 233, the processing difficulty of the fourth clamping portion 22 is reduced, and the processing efficiency of the distribution plate 2 is improved. In another embodiment, the second clamping portion 121 can also be a convex bump, and the fourth clamping portion 22 corresponds to a positioning hole.

[0050] This embodiment also provides a gas water heater, which includes the above-mentioned burner. The distribution plate 2 is fixedly mounted on the fire bar 1 by the first clamping part 111 and the third clamping part 21 and the second clamping part 121 and the fourth clamping part 22, so that the distribution plate 2 can be quickly installed without using fasteners such as screws, and the distribution plate 2 can be quickly removed from the fire bar 1, making the disassembly and assembly operation of the distribution plate 2 simple and easy, reducing the disassembly and assembly time and workload of the distribution plate 2, and improving the disassembly and assembly efficiency of the distribution plate 2.

[0051] The gas water heater has a powerful central heating function for the home, can meet the heating needs of multiple rooms, and can provide a large flow of constant temperature sanitary hot water for use in home bathing, kitchens, etc. Since the gas water heater is an existing mature product, the specific structure and working process of the gas water heater will not be described in detail.

[0052] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments.
