[0039] In one technical solution of the present invention, in the vertical direction, the height of the air inlet hole is lower than the combustion surface of the burner.

[0040] In this technical solution, high-temperature flue gas or high-temperature air will be generated above the top of the burner due to the combustion of the flame. The air inlet is set below the combustion surface of the burner to prevent high-temperature flue gas or high-temperature air from entering the first guide channel, thereby reducing the temperature of the gas in the first guide channel and improving the thermal insulation effect of the partition and the air mold.

[0042] In this technical solution, the extension direction of the insulation part is at a certain angle to the outlet direction of the first air outlet, so that the gas blown out of the first air outlet will exert a certain pressure on the insulation part while moving along the insulation part, thereby forming an insulating air film on the surface of the insulation part. The insulating air film can slow down the speed at which the air inside the frame transfers heat to the insulation part, thereby reducing the temperature of the insulation part.

[0043] In one technical solution of the present invention, the angle between the heat insulating portion and the side wall of the frame is greater than or equal to 3 degrees and less than or equal to 30 degrees.

[0044] In this technical solution, the angle between the outlet direction of the first air outlet and the insulation part is 3 to 30 degrees, so that the gas flowing out of the first air outlet can evenly form a layer of insulation air film on the insulation part, thereby reducing the temperature of the insulation part.

[0045] In one technical solution of the present invention, the burner is an atmospheric burner, including a flame bar assembly, which is arranged parallel to the insulation.

[0048] In one technical solution of the present invention, the height of the heat insulation portion above the burner is greater than or equal to 40 mm and less than or equal to 120 mm.

The cooling gap is provided between the first insulating portion and at least a portion of the inner wall of the frame. When air flows through the cooling gap, the temperature of the first insulating portion is lowered, further reducing the amount of heat transferred from the interior of the frame to the frame through the first insulating portion.

[0054] In this technical solution, air is blown out from the air outlet after passing through the cooling gap and blown toward the first thermal insulation part. While cooling the first thermal insulation part, a thermal insulation air film can also be formed on the surface of the first thermal insulation part. The thermal insulation air film can reduce the amount of heat transferred from the inside of the frame to the first thermal insulation part, further reduce the temperature of the first thermal insulation part, and thereby reduce the amount of heat transferred from the inside of the frame through the first thermal insulation part to the frame, thereby reducing heat loss inside the frame and improving the heating efficiency of the burner.

The second air outlet is provided on the sub-insulation section connected to the second insulation section, allowing the gas in the second air guide channel to be blown toward the second insulation section, thereby cooling the second insulation section.

DETAILED DESCRIPTION

[0094] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0095] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0096] Refer to the following Figures 1 to 17 Gas appliances according to some embodiments of the present invention are described.

[0097] Example 1:

[0098] like Figures 1 to 3 As shown, the gas equipment 10 is provided with a heat exchanger 60, a burner 500 and a fan 30 from top to bottom, wherein the burner 500 is arranged on the inner side of the frame 100, the fan 30 is arranged on the outer side of the frame 100, the heat exchanger 60 can be arranged outside the frame 100 or inside the frame 100, and the heat exchanger 60 can also be partially arranged inside the frame 100 and the other part is arranged outside the frame 100.

[0099] Specifically, if Figures 1 to 3 As shown, the frame 100 defines a chamber 11, the burner 500 is located on the lower side of the chamber 11, and the fan 30 is installed on the outer side of the frame 100, with the outlet of the fan 30 facing the burner 500. That is, when the fan 30 is activated, air is drawn into the chamber 11 and mixed with the fuel gas entering the burner 500 to form an air-fuel mixture to be burned. The air-fuel mixture is ignited in the burner 500, and the resulting high-temperature flue gas enters the upper side of the chamber 11 and flows to the heat exchanger 60, heating the water therein.

[0100] In order to prevent the heat of the high-temperature flue gas from being conducted out of the frame 100 and causing damage to the components of the gas equipment 10, a partition 200 is further provided on the inner side of the frame 100. The partition 200 is spaced apart from at least a portion of the inner wall of the frame 100, thereby constructing an air duct 50. For example, when the frame 100 is a square frame, the partition 200 is spaced apart from at least one side wall (at least one of the left wall, right wall, front wall and rear wall) of the frame 100. In other words, the frame 100 is arranged around the circumference of the partition 200, thereby constructing one or more circumferentially distributed air ducts 50 through the frame 100 and the partition 200. The air duct 50 can form a single-cavity air duct in the circumferential direction, or it can form a plurality of mutual air ducts in the circumferential direction.

[0101] Among them, part of the air sent by the fan 30 flows into the air duct 50, and the other part flows into the burner 500. That is, part of the air enters the burner 500 to participate in combustion, and the other part enters the air duct 50 to cool the frame 100 to prevent the frame 100 from overheating.

[0102] After many experiments, the inventors found that after the air flows for a distance in the air duct 50, the air temperature will rise to a relatively high temperature, making it impossible to cool the frame 100, resulting in failure of local cooling of the frame 100. Under the effect of heat conduction, the already cooled part of the frame 100 will inevitably be heated again, and ultimately the purpose of cooling the frame 100 cannot be achieved.

[0103] In this embodiment, the partition 200 is provided with a plurality of air outlet holes 52 in the direction of flow of the air duct 50. Thus, as the air flows in the air duct 50, multiple air streams are ejected into the chamber 11 step by step, thereby forming an air film on the inner side of the partition 200. This air film can block the hot air from flowing toward the partition 200, thereby preventing the air temperature in the air duct 50 from rising too high and failing to cool the frame 100.

[0104] In short, according to the gas device 10 of an embodiment of the present invention, an air duct 50 for air-cooling the frame 100 is constructed between the frame 100 and the partition 200, and the partition 200 is provided with a plurality of air outlet holes 52 in the flow direction of the air duct 50, thereby forming an air film on the inner side of the partition 200 to block the hot air from flowing toward the partition 200, thereby improving the air cooling effect of the air in the air duct 50 on the frame 100, effectively preventing high temperature from being conducted to the outside of the frame 100, and improving the service life of the components of the gas device 10.

[0105] The chamber 11 defined by the frame 100 is a closed chamber 11 . A fan 30 is provided outside the frame 100 to supply air into the frame 100 .

[0106] The fan 30 is arranged below the frame 100. The air sent into the frame 100 by the fan 30 moves upward from the bottom of the chamber 11. Part of the air enters the burner and mixes with the gas in the burner and burns at the fire grate; the other part of the air enters the air duct 50 and continues to move upward in the air duct 50, and then flows out from the air outlet 52 to form a flowing air film on the inner side of the partition 200.

[0107] Example 2:

[0108] like Figures 1 to 4 As shown, a plurality of turning portions 41 are formed on the partition 200. The turning portions 41 protrude from the inside to the outside, and the air outlets 52 are formed on the turning portions 41. Figure 15 As indicated by the wind direction arrows, the airflow flows from bottom to top along the air duct 50. After encountering the turning portion 41, a portion of the airflow is directed toward the burner 500, that is, it flows out through the air outlet 52 provided in the turning portion 41. In other words, the turning portion 41 intercepts the airflow in the air duct 50, diverting a portion of the airflow out of the air outlet 52, thereby forming an air film on the inner wall of the partition 200, blocking the hot air flow from flowing toward the frame 100.

[0109] In an optional embodiment, if Figures 1 to 4As shown, the turning portion 41 includes a first section 411 extending outward horizontally, a second section 412 connected to the first section 411 at one end and extending vertically upward, and a third section 413 connected to the second section 412 at one end and extending obliquely in the vertical direction. The air outlet 52 is formed in the first section 411. The obstruction of the first section 411 of the turning portion 41 abruptly reduces the flow area of the air duct 50, allowing some airflow to flow out of the air outlet 52 while the remaining airflow continues upward and out of the air outlet 52 of the other turning portion 41. Furthermore, the oblique extension of the third section 413 gradually increases the flow area of the air duct 50, allowing the airflow to flow upward more smoothly.

[0110] Example 3:

[0111] The air outlet holes 52 are horizontally extending strip-shaped holes. The strip-shaped air outlet structure can maximize the air outlet surface, so that an air film can be formed on the entire circumferential inner wall surface of the partition 200, blocking the hot air flow from approaching the frame 100, further preventing the frame 100 from overheating.

[0112] In an optional example, the air outlet holes 52 are evenly distributed along the circumferential direction of the partition, thereby forming a uniform air film on the entire circumferential inner wall surface of the partition 200, blocking the hot air flow from approaching the frame 100, and ensuring that the temperatures of various parts of the entire frame 100 are similar.

[0113] Example 4:

[0114] The air inlet area of the air duct 50 is larger than the air outlet area. Specifically, the total air inlet surface area on the lower side of the air duct 50 is larger than the total air outlet surface area of the air outlet holes 52 on the partition 200. This ensures that sufficient air flows throughout the air duct 50, preventing the air from being unable to continue flowing upward due to insufficient air flow at a certain height of the air duct 50, causing heat in the combustion chamber to flow back into the air duct 50. Optionally, the air inlet holes 214 of the air duct 50 are arranged around the burner 500.

[0115] In an optional embodiment, the ratio of the air inlet area to the air outlet area of the air duct 50 is between 5:2 and 4:3. To obtain a preferred ratio of air inlet area to air outlet area, the inventors conducted a large number of experiments. This is because the input air provided by the fan 30 is mainly used for the combustion of the burner 500. If a portion of the air is transported into the air duct 50 while the air intake of the fan 30 remains unchanged, this will inevitably lead to a reduction in the air intake of the burner 500, which may affect whether the gas in the burner 500 can be fully burned, that is, whether it will cause excessive waste gas emissions. Therefore, after comprehensively considering various factors, the inventors set the ratio of the air inlet area to the air outlet area of the air duct 50 to between 5:2 and 4:3, which can ensure that there is sufficient air in the air duct 50 and that the gas is fully burned.

[0116] Embodiment 5:

[0117] like Figures 1 to 3 As shown, the air inlet surface of the air duct 50 is lower than the combustion surface of the burner 500. In this way, the smoke generated by the combustion surface is blocked by the partition 200 and can be collected in the chamber 11 to prevent the smoke from acting on the frame 100.

[0118] In an optional embodiment, if Figures 1 to 3 As shown, a hollow boss 42 is further provided on the upper portion of the partition, extending toward the frame 100. The cavity of the hollow boss 42 forms an air outlet 52. The hollow boss 42 can force the airflow to bend before flowing upward, forming a vortex zone at the upper portion of the air duct 50. This allows the airflow to reach the top of the air duct 50 and then flow out of the air duct 50 through the hollow boss 42, thereby ensuring that the upper portion of the air duct 50 can also be cooled while forming an air film on the partition 200.

[0119] Considering that the airflow has relatively low pressure when it reaches the top of the duct 50, the distance between the hollow boss 42 and the top surface of the duct 50 should not be too long, as this may result in insufficient air pressure to push the airflow to the top of the duct 50. Preferably, the distance between the hollow boss 42 and the top surface of the duct 50 is d, the height of the duct 50 is h, and d / h is between 1 / 20 and 1 / 10. This allows an air film with good pressure to be formed on the inner wall of the partition 200, and air can be delivered to the top of the duct 50, thereby achieving a better cooling effect and ensuring that the temperature rise of the frame 100 is within a controllable range.

[0120] Example 6:

[0121] like Figures 1 to 3 As shown, the gas equipment 10 is provided with a heat exchanger 60, a burner 500 and a fan 30 from top to bottom, wherein the burner 500 is arranged on the inner side of the frame 100, the fan 30 is arranged on the outer side of the frame 100, the heat exchanger 60 can be arranged outside the frame 100 or inside the frame 100, and the heat exchanger 60 can also be partially arranged inside the frame 100 and the other part is arranged outside the frame 100.

[0122] Specifically, if Figures 1 to 3 As shown, the frame 100 defines a chamber 11, the burner 500 is located on the lower side of the chamber 11, and the fan 30 is installed on the outer side of the frame 100, with the outlet of the fan 30 facing the burner 500. That is, when the fan 30 is activated, air is drawn into the chamber 11 and mixed with the fuel gas entering the burner 500 to form an air-fuel mixture to be burned. The air-fuel mixture is ignited in the burner 500, and the resulting high-temperature flue gas enters the upper side of the chamber 11 and flows to the heat exchanger 60, heating the water therein.

[0123] In order to prevent the heat of the high-temperature flue gas from being conducted out of the frame 100 and causing damage to the components of the gas equipment 10, a partition 200 is further provided on the inner side of the frame 100. The partition 200 is spaced apart from at least a portion of the inner wall of the frame 100, thereby constructing an air duct 50. For example, when the frame 100 is a square frame, the partition 200 is spaced apart from at least one side wall (at least one of the left wall, right wall, front wall and rear wall) of the frame 100. In other words, the frame 100 is arranged around the circumference of the partition 200, thereby constructing one or more circumferentially distributed air ducts 50 through the frame 100 and the partition 200. The air duct 50 can form a single-cavity air duct in the circumferential direction, or it can form a plurality of mutual air ducts in the circumferential direction.

[0124] Among them, part of the air sent by the fan 30 flows into the air duct 50, and the other part flows into the burner 500. That is, part of the air enters the burner 500 to participate in combustion, and the other part enters the air duct 50 to cool the frame 100 to prevent the frame 100 from overheating.

[0125] After many experiments, the inventors found that after the air flows for a distance in the air duct 50, the air temperature will rise to a relatively high temperature, making it impossible to cool the frame 100, resulting in failure of local cooling of the frame 100. Under the effect of heat conduction, the already cooled part of the frame 100 will inevitably be heated again, and ultimately the purpose of cooling the frame 100 cannot be achieved.

[0126] In this embodiment, the partition 200 is provided with a plurality of air outlet holes 52 in the direction of flow of the air duct 50. Thus, as the air flows in the air duct 50, multiple air streams are ejected into the chamber 11 step by step, thereby forming an air film on the inner side of the partition 200. This air film can block the hot air from flowing toward the partition 200, thereby preventing the air temperature in the air duct 50 from rising too high and failing to cool the frame 100.

[0127] In short, according to the gas device 10 of an embodiment of the present invention, an air duct 50 for air-cooling the frame 100 is constructed between the frame 100 and the partition 200, and the partition 200 is provided with a plurality of air outlet holes 52 in the flow direction of the air duct 50, thereby forming an air film on the inner side of the partition 200 to block the hot air from flowing toward the partition 200, thereby improving the air cooling effect of the air in the air duct 50 on the frame 100, effectively preventing high temperature from being conducted to the outside of the frame 100, and improving the service life of the components of the gas device 10.

[0128] Embodiment seven:

[0129] like Figures 1 to 4 As shown, a plurality of turning portions 41 are formed on the partition 200. The turning portions 41 protrude from the inside to the outside, and the air outlets 52 are formed on the turning portions 41. Figure 2As indicated by the wind direction arrows, the airflow flows from bottom to top along the air duct 50. After encountering the turning portion 41, a portion of the airflow is directed toward the burner 500, that is, it flows out through the air outlet 52 provided in the turning portion 41. In other words, the turning portion 41 intercepts the airflow in the air duct 50, diverting a portion of the airflow out of the air outlet 52, thereby forming an air film on the inner wall of the partition 200, blocking the hot air flow from flowing toward the frame 100.

[0130] In an optional embodiment, if Figures 1 to 4 As shown, the turning portion 41 includes a first section 411 extending toward the sidewall of the frame, and a second section 412 connected to the first section 411 at one end and extending upward. The air outlet 52 is formed in the first section 411. Due to the obstruction of the first section 411 of the turning portion 41, the flow area of the air duct 50 is suddenly reduced, allowing part of the airflow to flow out of the air outlet 52, while the remaining part of the airflow continues to flow upward and out of the air outlet 52 of the other turning portion 41. In addition, the obliquely extending third section 413 gradually increases the flow area of the air duct 50, allowing the airflow to flow upward more smoothly.

[0131] Embodiment 8:

[0132] The air outlet holes 52 are horizontally extending strip-shaped holes. The strip-shaped air outlet structure can maximize the air outlet surface, so that an air film can be formed on the entire circumferential inner wall surface of the partition 200, blocking the hot air flow from approaching the frame 100, further preventing the frame 100 from overheating.

[0133] In an optional example, the air outlet holes 52 are evenly distributed along the circumferential direction of the partition, thereby forming a uniform air film on the entire circumferential inner wall surface of the partition 200, blocking the hot air flow from approaching the frame 100, and ensuring that the temperatures of various parts of the entire frame 100 are similar.

[0134] Embodiment 9:

[0135] The air inlet area of the air duct 50 is larger than the air outlet area. Specifically, the total air inlet surface area on the lower side of the air duct 50 is larger than the total air outlet surface area of the air outlet holes 52 on the partition 200. This ensures that sufficient air flows throughout the air duct 50, preventing the air from being unable to continue flowing upward due to insufficient air flow at a certain height of the air duct 50, causing heat in the combustion chamber to flow back into the air duct 50. Optionally, the air inlet holes 214 of the air duct 50 are arranged around the burner 500.

[0136] In an optional embodiment, the ratio of the air inlet area to the air outlet area of the air duct 50 is between 5:2 and 4:3. To obtain a preferred ratio of air inlet area to air outlet area, the inventors conducted a large number of experiments. This is because the input air provided by the fan 30 is mainly used for the combustion of the burner 500. If a portion of the air is transported into the air duct 50 while the air intake of the fan 30 remains unchanged, this will inevitably lead to a reduction in the air intake of the burner 500, which may affect whether the gas in the burner 500 can be fully burned, that is, whether it will cause excessive waste gas emissions. Therefore, after comprehensively considering various factors, the inventors set the ratio of the air inlet area to the air outlet area of the air duct 50 to between 5:2 and 4:3, which can ensure that there is sufficient air in the air duct 50 and that the gas is fully burned.

[0137] Embodiment 10:

[0138] like Figures 1 to 3 As shown, the air inlet surface of the air duct 50 is lower than the combustion surface of the burner 500. In this way, the smoke generated by the combustion surface is blocked by the partition 200 and can be collected in the chamber 11 to prevent the smoke from acting on the frame 100.

[0139] In an optional embodiment, if Figures 1 to 3 As shown, a hollow boss 42 is further provided on the upper portion of the partition, extending toward the frame 100. The cavity of the hollow boss 42 forms an air outlet 52. The hollow boss 42 can force the airflow to bend before flowing upward, forming a vortex zone at the upper portion of the air duct 50. This allows the airflow to reach the top of the air duct 50 and then flow out of the air duct 50 through the hollow boss 42, thereby ensuring that the upper portion of the air duct 50 can also be cooled while forming an air film on the partition 200.

[0140] Considering that the airflow has relatively low pressure when it reaches the top of the duct 50, the distance between the hollow boss 42 and the top surface of the duct 50 should not be too long, as this may result in insufficient air pressure to push the airflow to the top of the duct 50. Preferably, the distance between the hollow boss 42 and the top surface of the duct 50 is d, the height of the duct 50 is h, and d / h is between 1 / 20 and 1 / 10. This allows an air film with good pressure to be formed on the inner wall of the partition 200, and air can be delivered to the top of the duct 50, thereby achieving a better cooling effect and ensuring that the temperature rise of the frame 100 is within a controllable range.

[0141] Example 11:

[0142] The partition is connected to the side wall of the frame, and the partition includes: an insulating portion arranged obliquely to the side wall of the frame, an end of the insulating portion away from the side wall of the frame is bent outward to form a turning portion, and / or an end of the insulating portion close to the side wall of the frame is bent inward to form a turning portion.

[0143] The partition also includes a guide part, one end of the guide part is connected to the frame, and the other end of the guide part is connected to the insulation part. An air inlet hole 214 of the air duct is formed on the guide part. The guide part and the side wall of the frame enclose a first guide channel. A first air outlet is provided on the guide part. The first air outlet is connected to the first guide channel and faces the insulation part.

[0144] Example 12:

[0145] like Figure 5 and Figure 9 As shown, the thermal insulation portion 220 includes a first thermal insulation segment 222 and a second thermal insulation segment 226 .

[0146] like Figure 7 As shown, the first air outlet 212 faces the first thermal insulation section 222, the first thermal insulation section 222 and the frame 100 enclose a second guide channel 400, the second guide channel 400 is connected to the first guide channel 300, and a second air outlet 224 is provided on the first thermal insulation section 222, the second air outlet 224 is connected to the second guide channel 400; the second air outlet 224 faces the second thermal insulation section 226.

[0147] In this embodiment, if Figure 6 and Figure 7 As shown, the air blown out from the first air outlet 212 can be blown toward the first insulation section 222, cooling the first insulation section 222 while also forming an air mold on the first insulation section 222, thereby lowering the temperature of the first insulation section 222. A second guide channel 400 is provided between the first insulation section 222 and the frame 100. The air flowing in the second guide channel 400 can further cool the first insulation section 222, further lowering the temperature of the first insulation section 222. The first insulation section 222 is provided with a second air outlet 224 connected to the second guide channel 400. The air in the second guide channel 400 can be blown from the second air outlet 224 toward the second insulation section 226, cooling the second insulation section 226 while also forming an air mold on the second insulation section 226, thereby lowering the temperature of the second insulation section 226.

[0148] The heat insulating portion 220 includes at least two heat insulating sections, namely a first heat insulating section 222 and a second heat insulating section 226 , which further reduce the temperature of the heat insulating portion 220 and enhance the cooling effect of the heat insulating portion 220 .

[0149] Example 13:

[0150] like Figure 8 and Figure 9 As shown, the lower part of the first insulation section 222 is connected to the guide part 210 and is arranged opposite to the first air outlet 212. The upper part of the first insulation section is connected to the second insulation section 226 and is provided with the second air outlet 224. The top of the first insulation section 222 is bent and connected to the frame.

[0151] like Figure 8 and Figure 9 As shown, the first thermal insulation section 222 is connected to the second thermal insulation section 226 , and one end of the second thermal insulation section 226 connected to the first thermal insulation section 222 is in contact with the frame 100 .

[0152] In this embodiment, the second insulation section 226 is in contact with the frame 100, so that the gas in the second guide channel 400 will no longer continue to flow when it flows to the second air outlet 224, but will be blown from the second air outlet 224 to the second insulation section 226, thereby achieving the diversion of the gas in the second guide channel 400, improving the utilization rate of the gas in the second guide channel 400, and thus improving the heat dissipation efficiency of the second insulation section 226.

[0153] Example 14:

[0154] like Figure 10 As shown, the multiple sub-insulation segments include adjacent sub-insulation segments, and a third air outlet 228 is provided on a sub-insulation segment close to the guide portion 210 in the adjacent sub-insulation segments, and the third air outlet 228 faces another sub-insulation segment in the adjacent sub-insulation segments.

[0155] In this embodiment, the first insulation section 222 is provided with multiple sub-insulation sections. The first air outlet 212 faces the sub-insulation section connected to the air guide portion 210, thereby cooling this sub-insulation section. The second air outlet 224 is provided on the sub-insulation section connected to the second insulation section 226, thereby allowing the gas within the second air guide channel 400 to be blown toward the second insulation section 226, thereby cooling the second insulation section 226. All sub-insulation sections are sequentially connected. Among adjacent sub-insulation sections, the sub-insulation section closer to the air guide portion 210 is provided with a third air outlet 228. The gas within the second insulation section 400 is blown through the third air outlet 228 toward the sub-insulation section closer to the second insulation section 226, thereby cooling the sub-insulation section closer to the second insulation section 226.

[0156] like Figure 10 As shown, the insulation part 220 includes four insulation sections, that is, the first insulation section 222 includes three sub-insulation sections, namely the first sub-insulation section 2222, the second sub-insulation section 2224 and the third sub-insulation section 2226; the first side of the first sub-insulation section 2222 is connected to the guide part 210, and the other side is connected to one side of the second sub-insulation section 2224, the other side of the second sub-insulation section 2224 is connected to one side of the third sub-insulation section 2226, and the other side of the third sub-insulation section 2226 is connected to the second insulation section 226.

[0157] The first sub-insulation section 2222 and the second sub-insulation section 2224 are arranged adjacent to each other. Among the first sub-insulation section 2222 and the second sub-insulation section 2224, the first sub-insulation section 2222 is closer to the guide part 210, so the first sub-insulation section 2222 is provided with a third air outlet 228, and the third air outlet 228 on the first sub-insulation section 2222 is arranged toward the second sub-insulation section 2224.

[0158] The second sub-insulation section 2224 and the third sub-insulation section 2226 are arranged adjacent to each other. Among the second sub-insulation section 2224 and the third sub-insulation section 2226, the second sub-insulation section 2224 is closer to the guide part 210, so the second sub-insulation section 2224 is also provided with a third air outlet 228, and the third air outlet 228 on the second sub-insulation section 226 is arranged toward the third sub-insulation section 2226.

[0159] Embodiment 15:

[0160] like Figure 11 As shown, the insulation part 220 includes five insulation sections, that is, the first insulation section 222 includes four sub-insulation sections, namely the first sub-insulation section 2222, the second sub-insulation section 2224, the third sub-insulation section 2226 and the fourth sub-insulation section 2228; the first side of the first sub-insulation section 2222 is connected to the guide part 210, and the other side is connected to one side of the second sub-insulation section 2224, the other side of the second sub-insulation section 2224 is connected to one side of the third sub-insulation section 2226, the other side of the third sub-insulation section 2226 is connected to one side of the fourth sub-insulation section 2228, and the other side of the fourth sub-insulation section 2228 is connected to the second insulation section 226.

[0161] The first sub-insulation section 2222 and the second sub-insulation section 2224 are arranged adjacent to each other. Among the first sub-insulation section 2222 and the second sub-insulation section 2224, the first sub-insulation section 2222 is closer to the guide part 210, so the first sub-insulation section 2222 is provided with a third air outlet 228, and the third air outlet 228 on the first sub-insulation section 2222 is arranged toward the second sub-insulation section 2224.

[0162] The second sub-insulation section 2224 and the third sub-insulation section 2226 are arranged adjacent to each other. Among the second sub-insulation section 2224 and the third sub-insulation section 2226, the second sub-insulation section 2224 is closer to the guide part 210, so the second sub-insulation section 2224 is also provided with a third air outlet 228, and the third air outlet 228 on the second sub-insulation section 2224 is arranged toward the third sub-insulation section 2226.

[0163] The third sub-insulation segment 2226 and the fourth sub-insulation segment 2228 are arranged adjacent to each other. Among the third sub-insulation segment 2226 and the fourth sub-insulation segment 2228, the third sub-insulation segment 2226 is closer to the guide part 210, so the third sub-insulation segment 2226 is also provided with a third air outlet 228, and the third air outlet 228 on the third sub-insulation segment 2226 is arranged toward the fourth sub-insulation segment 2228.

[0164] like Figures 15 to 17 As shown, in the vertical direction, the height of the air inlet hole 214 is lower than the combustion surface of the burner.

[0165] High-temperature flue gas or high-temperature air will be generated above the top of the burner 500 due to the combustion of the flame. The air inlet 214 is set below the combustion surface of the burner 500 to prevent high-temperature flue gas or high-temperature air from entering the first guide channel 300, thereby reducing the temperature of the gas in the first guide channel 300 and improving the thermal insulation effect of the partition 200 and the gas mold.

[0166] Example 16:

[0167] The included angle between the heat insulating portion 220 and the side wall of the frame is greater than or equal to 3 degrees and less than or equal to 30 degrees.

[0168] In this embodiment, the angle between the frame side wall and the insulation part 220 is 3 degrees to 30 degrees, so that the gas flowing out of the first air outlet 212 can evenly form a layer of insulation air film on the insulation part 220, thereby reducing the temperature of the insulation part 220.

[0169] like Figure 13 As shown, there are multiple first air outlet holes 212, and the multiple first air outlet holes 212 are evenly arranged along the length or width direction of the frame. The air outlet direction of the first air outlet holes 212 is the same as the direction of smoke flow. The air outlet directions of the second air outlet holes 224 and the third air outlet holes 228 are the same as the air outlet direction of the first air outlet holes 212.

[0170] like Figure 14 As shown, there are multiple second air outlet holes 224, and the multiple second air outlet holes 224 are evenly arranged along the length or width direction of the frame. The angle between the air outlet direction of the second air outlet holes 224 and the insulation section corresponding to the second air outlet holes 224 is 3 degrees to 30 degrees.

[0171] There are multiple third air outlet holes 228, which are evenly arranged along the length or width of the frame. The angle between the air outlet direction of the third air outlet holes 228 and the corresponding insulation section is 3 to 30 degrees.

[0172] Embodiment 17:

In this embodiment, the burner 500 is an atmospheric burner, and the burner 500 includes a fire bar assembly, and the fire bar assembly is arranged parallel to the heat insulation portion 220, so that the heat insulation portion 220 can effectively prevent the heat generated by the fire bar assembly from being transferred to the frame 100, further improving the heat insulation effect of the heat insulation portion 220.

[0174] Embodiment 18:

[0175] like Figure 1 and Figure 7 As shown, there are multiple heat insulating parts 220 , and the heat insulating parts 220 are arranged on both sides of the burner 500 , or are arranged around the burner 500 .

[0176] In this embodiment, the burner 500 is arranged on the inner side of the frame, and the insulation part 220 is arranged on both sides of the burner 500, or is arranged around the burner 500, so as to prevent the heat generated by the burner 500 from being transferred to the frame and causing aging or deformation of the frame, and to reduce heat loss inside the frame, thereby improving the heating efficiency of the burner 500.

[0177] Embodiment 19:

[0178] like Figure 16 As shown, the heat insulating portion 220 is located above the burner 500, and is correspondingly arranged at a height H above the combustion chamber cavity that is greater than or equal to 40 mm.

[0179] In this embodiment, the height of the heat insulating portion 220 is set to be 40 mm higher than the top of the burner 500 to ensure that the heat insulating portion 220 can effectively isolate the heat generated by the burner 500.

[0180] The height of the bottom end of the partition 200 is lower than or equal to the height of the top surface of the burner 500, so as to cover the combustion part of the burner to achieve heat insulation.

[0181] The height of the partition plate 200 is determined according to the height of the combustion chamber in the gas device 10 .

[0182] The gas equipment 10 further includes a heat exchanger 700 , which is disposed above the burner 500 . Water in the heat exchanger 700 can perform heat exchange with high-temperature gas in the combustion chamber.

Among the first sub-insulation section 2222 and the second sub-insulation section 2224, the first sub-insulation section 2222 is closer to the guide part 210, so the first sub-insulation section 2222 is provided with a third air outlet 228, and the third air outlet 228 on the first sub-insulation section 2222 is arranged toward the second sub-insulation section 2224.
