[0041] A gas water heater is a device that heats water by releasing heat through gas combustion. A good ratio of air and gas (air-fuel ratio) needs to be maintained during the combustion process to achieve stable and sufficient combustion. In the related art, a temperature sensor is used to detect the flame temperature to adjust and control the air-fuel ratio. However, since the temperature sensor is not associated with the fire grate, when there is a deviation in the assembly of the fire grate or the installation of the temperature sensor, the temperature sensor is prone to deviation from the burner fire grate, resulting in inaccurate and poor consistency of the detected flame temperature, causing misregulation problems.

[0042] Based on this, the utility model proposes a burner, which is applied to gas equipment, and is intended to associate a temperature detection device with a fire grate, so that the temperature detection device can be fixed relative to the fire grate, so that the detection part of the temperature detection device is located in the flame zone required for detection, so as to ensure the accuracy of flame temperature detection and improve the control accuracy of air-fuel ratio adjustment. It can be understood that the gas equipment is not limited to a specific type of equipment, such as a gas water heater, a boiler, a wall-mounted boiler, etc. The burner will be described in the following by way of example.

[0043] like Figure 1 and Figure 2 As shown, the burner includes a housing 100 , a plurality of fire bars 200 and at least one temperature detection device 400 .

[0044] A plurality of fire bars 200 are arranged side by side on the shell 100, and a fire hole 201 is provided on the top surface of the fire bar 200 to form a flame zone above the fire hole 201; at least one fire bar 200 is provided with a limiting bracket 300; at least one temperature detection device 400 is installed on the shell 100, and a detection part 410 of the temperature detection device 400 is limited to the flame zone of the corresponding fire bar 200 by the corresponding limiting bracket 300.

[0045] It can be understood that the shell 100 plays a role in supporting and installing multiple fire bars 200. Multiple fire bars 200 are arranged side by side in the shell 100, and a fire outlet 201 is provided on the top thereof. After the gas and air are mixed in the fire bar 200, they are ejected from the fire outlet 201 on the top and ignited and burned to form a flame zone in the area above the fire outlet 201. In order to detect the flame temperature, this embodiment installs at least one temperature detection device 400 on the shell 100, and at the same time, a limiting bracket 300 is provided on at least one fire bar 200. The limiting bracket 300 can limit the detection part 410 of the temperature detection device 400, so that the detection part 410 is always in the flame zone of its corresponding fire bar 200, so as to accurately detect the temperature of the corresponding flame zone.

[0046] It should be noted that the limit bracket 300 in this embodiment is fixed on the fire grate 200, and the detection part 410 of the temperature detection device 400 is limited on the limit bracket 300, that is, the detection part 410 of the temperature detection device 400 is associated with the position of the fire grate 200. When the position of the fire grate 200 shifts during the assembly process, the limit bracket 300 fixed on the fire grate 200 will drive the detection part 410 of the temperature detection device 400 to shift together, so that the relative position of the detection part 410 and the flame zone of the fire grate 200 remains unchanged, thereby ensuring the consistency and stability of the temperature detection device 400 in detecting the flame temperature of the fire grate 200, ensuring the accuracy of the flame temperature detection, and further improving the accuracy of the air-fuel ratio adjustment of the burner.

[0047] In actual application, the number of fire bars 200 provided with the limiting bracket 300 can be determined according to the actual situation. For example, one of the fire bars 200 can be provided with the limiting bracket 300, or several of the fire bars 200 can be provided with the limiting bracket 300, or all of the fire bars 200 can be provided with the limiting bracket 300. Accordingly, the number and installation position of the temperature detection device 400 can be determined according to the actual situation. For example, when all the fire bars 200 are not opened in partitions, the limiting bracket 300 of one of the fire bars 200 can correspond to one temperature detection device 400; when multiple fire bars 200 are opened in partitions, a temperature detection device 400 can be provided in each area, etc. The number and installation position of the temperature detection device 400 are not specifically limited here.

[0048] In actual application, the specific structure of the limit bracket 300 can be determined according to the actual situation, for example, it can be a block, plate, strip or other special-shaped structure, as long as it can limit the temperature detection device 400 and limit its detection part 410 to the corresponding flame area. The limiting method of the detection part 410 by the limit bracket 300 can also be determined according to the actual situation, for example, it can be an axial hole limit, a baffle limit or other limiting methods. The connection method between the limit bracket 300 and the fire bar 200 can be welding fixation, buckle fixation, screw fixation or other fixing methods, and its specific fixing method is not limited here.

[0049] In practical applications, the temperature detection device 400 can be a high-temperature thermocouple, a temperature sensor, etc. The temperature detection device 400 can have a probe part (i.e., the detection part 410 in this embodiment) and an electric control part (which can be built into the fixing part 420), wherein the probe part can be located above the fire outlet 201 to detect the flame temperature of the flame zone, and the rear-end electric control part outputs the corresponding flame temperature detection signal to the corresponding control device in the gas equipment. The temperature detection device 400 and the housing 100 can be installed by welding, snap-fitting, screwing or other fixing methods.

[0050] In the burner of the utility model technical solution, a plurality of fire bars 200 are arranged side by side on the shell 100, and a fire outlet hole 201 is provided on the top surface of the fire bar 200 to form a flame zone above the fire outlet hole 201. By arranging a limiting bracket 300 on at least one fire bar 200 and arranging at least one temperature detection device 400 on the shell 100, the temperature detection device 400 can cooperate with the limiting bracket 300 so that its detection part 410 can be limited by the limiting bracket 300 to the flame zone of the corresponding fire bar 200, so that when the position of the fire bar 200 and the shell 100 is offset, the temperature detection device 400 can move with the fire bar 200, so that the detection part 410 of the temperature detection device 400 can still be in the flame zone of the corresponding fire bar 200 without being offset from the corresponding flame zone, so that the flame temperature can be accurately detected, the accuracy of the flame temperature detection is guaranteed, and the accuracy of the air-fuel ratio adjustment can be improved.

[0051] In one embodiment of the present application, Figure 1 and Figure 2 The limiting bracket 300 is fixedly arranged on one side of the fire bar 200 in the length direction; the detection part 410 is located in the flame zone on one side of the fire bar 200 in the length direction.

[0052] It is understandable that the fire hole 201 is located on the top surface of the fire bar 200, and its corresponding flame zone is located above the top of the fire bar 200. In this embodiment, by fixing the limit bracket 300 on one side of the length direction of the fire bar 200, there will be no interference with the fire hole 201 and the flame zone, thereby ensuring the uniformity of the flame. At the same time, the detection part 410 of the temperature detection device 400 is limited in the corresponding flame zone by the limit bracket 300 on one side of the length direction, so that other parts of the temperature detection device 400 except the detection part 410 will not be directly burned by the flame, further improving the reliability of the temperature detection device 400 and extending its service life.

[0053] In one embodiment of the present application, Figure 1 and Figure 2 The top surface of the fire bar 200 has a main fire hole 201a and side fire holes 201b arranged on both sides of the main fire hole 201a in the width direction. A main flame zone is formed above the main fire hole 201a, and a side flame zone is formed above the side fire holes 201b; the detection part 410 of the temperature detection device 400 is located in the side flame zone.

[0054] It can be understood that the side fire holes 201b are respectively provided on both sides of the main fire hole 201a on the top surface of the fire bar 200. On the one hand, the gas outlet area on the top of the fire bar 200 can be increased to make the flame more uniform. On the other hand, the side fire holes 201b play a role in assisting combustion and stabilizing the flame. In actual application, the flame temperature of the side flame zone above the side fire holes 201b is lower than the flame temperature of the main flame zone above the main fire hole 201a. By locating the detection part 410 of the temperature detection device 400 in the side flame zone, it can be avoided that the main flame temperature is too high and affects the life of the detection part 410. Such a setting is conducive to improving the life of the temperature detection device 400.

[0055] In one embodiment of the present application, Figure 1 , Figure 2 , Figure 4 as well as Figure 5 The limiting bracket 300 is provided with a limiting through hole 301 extending along the length direction of the fire bar 200, and the temperature detection device 400 is inserted and matched in the limiting through hole 301 so that the detection part 410 extends into the corresponding flame area.

[0056] This embodiment illustrates the limiting cooperation mode of the limiting bracket 300 and the temperature detection device 400. The limiting bracket 300 is provided with a limiting through hole 301, and the temperature detection device 400 is inserted and matched in the limiting through hole 301. The two are limited by the shaft hole. It can be understood that the limiting through hole 301 corresponds to the flame zone of the fire bar 200 to be detected, and the axis extension line of the limiting through hole 301 can extend to the corresponding flame zone, so that when the temperature detection device 400 is inserted in the limiting through hole 301, its detection part 410 can extend into the corresponding flame zone for detection.

[0057] It can be understood that since the temperature detection device 400 is limited by the axial hole of the limiting bracket 300, when the position of the fire grate 200 is offset, the limiting bracket 300 can drive the temperature detection device 400 to offset along with the fire grate 200 through the limiting through hole 301, so that the detection part 410 is always in the corresponding flame zone, ensuring the detection accuracy.

[0058] In one embodiment of the present application, Figures 2 to 5 as well as Figure 7 The temperature detection device 400 also includes a fixing portion 420 , one end of which is fixedly connected to the housing 100 , and the other end is installed in the limiting through hole 301 , and the detection portion 410 is disposed at one end of the fixing portion 420 away from the housing 100 .

[0059] In this embodiment, the fixing portion 420 serves to fix the temperature detection device 400 to the housing 100. The detection portion 410 is disposed at one end of the fixing portion 420, and when the fixing portion 420 is passed through the limiting through hole 301, the detection portion 410 can smoothly extend into the corresponding flame zone.

[0060] Specifically, Figures 3 to 7 The fixing part 420 is an axial structure, and a boss 430 is provided on the outer peripheral wall of the fixing part 420; the shell 100 is provided with a mounting hole 101 corresponding to the limiting through hole 301, and the fixing part 420 is sequentially penetrated through the mounting hole 101 and the limiting through hole 301, and the boss 430 is abutted against the outer wall surface of the shell 100.

[0061] In this embodiment, a boss 430 is provided on the outer peripheral wall of the fixing portion 420, and the boss 430 plays a role of abutting and limiting the housing 100. During installation, the detection portion 410 and the fixing portion 420 are sequentially inserted into the installation hole 101 and the limiting through hole 301 until the boss 430 abuts against the outer wall surface of the housing 100, completing the pre-installation of the temperature detection device 400, and then the boss 430 is fixed to the housing 100 by welding, screwing or clamping.

[0062] Furthermore, if Figure 3 and Figure 7 the outer diameter of the boss 430 is larger than the aperture of the mounting hole 101, so that the boss 430 can block the gap between the mounting hole 101 and the fixing portion 420.

[0063] It can be understood that the outer diameter of the detection part 410 is smaller than the outer diameter of the fixing part 420, and the outer diameter of the fixing part 420 is smaller than the aperture size of the mounting hole 101. This arrangement makes it easier for the detection part 410 and the fixing part 420 to be inserted into the mounting hole 101, thereby improving assembly efficiency.

[0064] By setting the outer diameter of the boss 430 to be larger than the aperture of the mounting hole 101, when the temperature detection device 400 is installed in place, the boss 430 can completely block the mounting hole 101, so that the gap between the mounting hole 101 and the fixing part 420 is blocked, so that external airflow will not enter the burner through the gap between the mounting hole 101 and the fixing part 420, affecting the stability of the burning flame of the fire grate 200 there.

[0065] In one embodiment of the present application, Figure 2 , Figures 4 to 6The limiting bracket 300 includes a connecting plate 310 and a limiting plate 320. The connecting plate 310 is fixedly connected to one side of the fire bar 200 in the length direction. One end of the limiting plate 320 is connected to the connecting plate 310, and the other end is extended away from the connecting plate 310 along the width direction of the fire bar 200. The limiting through hole 301 is provided on the limiting plate 320.

[0066] This embodiment illustrates the structure of the limit bracket 300, and the connecting plate 310 serves to install and connect the limit plate 320 and the fire bar 200. The connecting plate 310 and the fire bar 200 can be fixed by welding or snapping. The limit plate 320 and the connecting plate 310 are arranged at an angle, one end of the limit plate 320 is connected to the connecting plate 310, and the other end extends along the width direction of the fire bar 200. Then, the limit plate 320 is located on one side of the fire bar 200 in the width direction, so that the limit through hole 301 corresponds to the flame zone on one side of the fire bar 200, so that the detection part 410 of the temperature detection device 400 is located in the side flame zone at the top of the fire bar 200, avoiding the main flame temperature from being too high, which is conducive to improving the life of the temperature detection device 400.

[0067] Specifically, Figure 2 , Figures 4 to 6 A limiting groove 202 is provided on one side of the fire bar 200 in the length direction, and a first flange 311 is provided on the side of the connecting plate 310 away from the limiting plate 320. The first flange 311 is buckled in the limiting groove 202 so that the limiting plate 320 and the side edge of the fire bar 200 in the length direction are abutted against each other; a second flange 312 is provided on the top edge of the connecting plate 310, and the second flange 312 is buckled in the top edge of the fire bar 200.

[0068] During actual installation, the first flange 311 is buckled with the limiting groove 202, so that the limiting plate 320 abuts against the side edge of the fire bar 200 in the length direction, thereby realizing the limiting of the limiting bracket 300 and the fire bar 200 in the length direction of the fire bar 200; the second flange 312 is buckled with the top edge of the fire bar 200, thereby realizing the limiting of the limiting bracket 300 and the fire bar 200 in the height direction and width direction of the fire bar 200; thereby, the pre-installation of the limiting bracket 300 and the fire bar 200 is realized, which is more conducive to the welding and fixation of the limiting bracket 300 and the fire bar 200, and further improves the assembly efficiency.

[0069] In practical application, the limiting bracket 300 is an integral part, the connecting plate 310 can be formed by bending the edge of the limiting plate 320, and the first flange 311 and the second flange 312 can be formed by bending the edge of the connecting plate 310. Such a configuration can simplify the molding process of the limiting bracket 300 and further improve the production efficiency of the burner.

[0070] The utility model also provides a gas device, which includes a heat exchanger and a burner. The specific structure of the burner refers to the above embodiment. Since the gas device adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0071] Optionally, the combustion equipment may also be a gas water heater, a boiler, a wall-mounted boiler or the like.

[0072] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
