[0069] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0070] Combine the following Figure 1-Figure 10 , describing an embodiment of the present invention.

[0071] According to an embodiment of the present invention, on the one hand, a combustion plate assembly is provided, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes: a combustion plate 110 and a fire hole plate 120.

[0072] The combustion plate 110 includes a first surface and a second surface that are arranged opposite to each other. The combustion plate 110 is provided with a plurality of first gas delivery grooves 111 that penetrate the first surface and the second surface. The air inlet of the first gas delivery groove 111 is used to communicate with the first gas source; the fire hole plate 120 covers the first surface. The fire hole plate 120 is provided with a plurality of fire hole groups. Each fire hole group includes a plurality of fire holes 121. One fire hole group is connected to one first gas delivery groove 111. The air outlet of the first gas delivery groove 111 is used to communicate with the combustion chamber 300 through the fire hole 121.

[0073] In the above embodiment, a fire hole plate 120 is additionally provided on the combustion plate 110, and a fire hole 121 connected to the first gas supply groove 111 of the combustion plate 110 is provided on the fire hole plate 120, so that the first gas supply groove 111 for gas supply and the fire hole 121 for flame combustion are designed to be split, and the combustion plate 110 and the fire hole plate 120 can be cast separately; the fire hole plate 120 is provided with a plurality of groups of fire hole groups, and a plurality of fire holes 121 of each group of fire hole groups are connected to a first gas supply groove 111, so that a first gas supply groove 111 can supply gas to a plurality of fire holes 121 for flame combustion, and on the basis of ensuring the small size design of the fire hole 121, a relatively large-sized gas supply channel can be provided for the first gas supply groove 111, thereby reducing the manufacturing difficulty of the combustion plate 110.

[0074] At the same time, the combustion plate 110 and the fire hole plate 120 are easy to disassemble and assemble, which is conducive to later maintenance and replacement. Moreover, the combustion plate 110 and the fire hole plate 120 can be manufactured separately, which can simplify the process and help save costs. At the same time, the combustion plate assembly provided in this embodiment has a simple and compact structure and high space utilization, which is conducive to the miniaturization of gas devices and gas equipment.

[0075] Specifically, if Figure 2 , Figure 3 As shown, the first surface of the combustion plate 110 is the side close to the fire hole plate 120, and the second surface of the combustion plate 110 is the side away from the fire hole plate 120. The fire hole plate 120 covers the first surface of the combustion plate 110 and is fixedly connected by a number of fasteners. A plurality of first gas delivery grooves 111 are arranged on the combustion plate 110, and a plurality of groups of fire holes 121 are arranged on the fire hole plate 120 corresponding to each combustion plate 110. Each group of fire holes 121 includes at least two adjacently arranged fire holes 121. After the fire hole plate 120 is covered on the first surface of the combustion plate 110, a first gas delivery groove 111 corresponding to each group of fire holes 121 is connected. After the first gas source is supplied to the air inlet of the first gas delivery groove 111, it is discharged from the air outlet of the first gas delivery groove 111 and reaches the corresponding group of fire holes 121, and then flame combustion is carried out in the combustion chamber 300 through electric spark ignition.

[0076] Furthermore, the combustion plate assembly provided in this embodiment changes the design form of one gas delivery channel corresponding to one fire hole in the related art, and adopts a design form of one first gas delivery groove 111 corresponding to multiple fire holes 121. The first gas delivery groove 111 on the combustion plate 110 is only used for gas delivery, so that the gas delivered through the first gas delivery groove 111 is supplied to a group of multiple fire holes 121 for flame combustion. More specifically, Figure 3 , Figure 4As shown, in this embodiment, multiple small-sized gas delivery channels are optimized into 24 relatively large-sized first gas delivery grooves 111, which is equivalent to increasing the area of ​​a single gas delivery channel by several times. The increase in the size of the first gas delivery groove 111 reduces the difficulty of die casting, thereby reducing the difficulty of manufacturing the combustion plate 110. At the same time, the fire hole plate 120 itself is set as a thin plate structure, and even if it is necessary to process multiple dense fire holes 121 thereon, its processing difficulty is greatly reduced.

[0077] Furthermore, in this embodiment, the plurality of adjacent fire holes 121 in each fire hole group are configured as tiny holes, so that when the flame burns on the upper surface of the fire hole 121, it is not easy to transfer the flame downward, thus avoiding the problem of flashback. Figure 3 , Figure 4 As shown, each group of fire holes 121 includes twenty fire holes 121, that is, in this embodiment, one first gas delivery slot 111 can deliver gas for twenty fire holes 121 to perform flame combustion. This embodiment does not limit the shape of the fire holes 121, and the fire holes 121 can be set to rectangular, triangular, circular, etc.

[0078] Furthermore, if Figure 2 As shown, the first surface of the combustion plate 110 is provided with a positioning column 114, and the fire hole plate 120 is provided with a positioning column 114 and a positioning groove 122 correspondingly. When the combustion plate 110 and the fire hole plate 120 are assembled, the positioning column 114 and the positioning groove 122 are aligned and plugged.

[0079] Furthermore, in this embodiment, as a preferred implementation, the fire hole plate 120 is made of a stainless steel plate.

[0080] In some embodiments, Figure 3 , Figure 5 As shown, the combustion plate 110 is further provided with a second gas delivery groove 112 connected to the first gas delivery groove 111, and the second gas delivery groove 112 is used to be connected to a second gas source.

[0081] In the above embodiment, the combustion plate 110 is further provided with a second gas delivery groove 112 which is connected to the first gas delivery groove 111 and can be fed with a second gas source, thereby enabling the combustion plate assembly to adjust a variety of firepower working ranges.

[0082] Specifically, if Figure 2 , Figure 3 , Figure 5As shown, a first gas source is introduced into the fire hole 121 through the first gas delivery groove 111, and the first gas source enters the combustion chamber 300 after entering the fire hole 121, and is ignited by the electric spark in the combustion chamber 300, thereby burning in the combustion chamber 300; a second gas source is introduced into the second gas delivery groove 112, and the second gas source enters the second gas delivery groove 112 and is further introduced into the first gas delivery groove 111, and then enters the combustion chamber 300 through the fire hole 121, and is ignited by the electric spark in the combustion chamber 300, thereby burning in the combustion chamber 300; thereby, the combustion mode of the dual combustion system is realized to adjust a variety of firepower working ranges.

[0083] In some embodiments, Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the second gas delivery groove 112 is formed by the depression of the first surface; the combustion plate 110 is also provided with a connecting groove 113 formed by the depression of the first surface, and the connecting groove 113 is connected between the first gas delivery groove 111 and the second gas delivery groove 112; when the fire hole plate 120 covers the first surface, the second gas delivery groove 112 and the connecting groove 113 are shielded.

[0084] In the above embodiment, the first gas delivery groove 111 and the second gas delivery groove 112 are connected via the connecting groove 113, so that gas is delivered from the second gas delivery groove 112 to the first gas delivery groove 111 via the connecting groove 113; when the fire hole plate 120 is covered on the first surface, the second gas delivery groove 112 and the connecting groove 113 are shielded, thereby realizing a closed setting on the gas flow path of the second gas delivery groove 112-connecting groove 113-first gas delivery groove 111, thereby preventing gas from escaping from the first surface of the combustion plate 110.

[0085] Specifically, if Figure 6 , Figure 7 , Figure 8 As shown, since the second gas delivery groove 112 and the connecting groove 113 are both semi-closed groove structures formed by the depression of the first surface of the combustion plate 110, when the fire hole plate 120 covers the first surface, the exposed parts of the second gas delivery groove 112 and the connecting groove 113 are covered by the part of the fire hole plate 120 where the fire hole 121 is not provided, thereby realizing the closed setting on the gas flow path of the second gas delivery groove 112-connecting groove 113-first gas delivery groove 111.

[0086] In some embodiments, Figure 3 , Figure 5 As shown, the first gas delivery groove 111 and the second gas delivery groove 112 are both arranged in a strip shape, and the first gas delivery groove 111 and the second gas delivery groove 112 are arranged in the same direction; the first gas delivery groove 111 is adjacently arranged on both sides of the second gas delivery groove 112 in the length direction, and the connecting groove 113 is arranged on the partition wall between the first gas delivery groove 111 and the second gas delivery groove 112.

[0087] In the above embodiment, the connecting groove 113 is directly provided on the partition wall between the first gas delivery groove 111 and the second gas delivery groove 112 to facilitate the die-casting process of the combustion plate 110 .

[0088] Specifically, Figure 3 , Figure 5 As shown, the first gas delivery grooves 111 are evenly spaced and arranged, and a plurality of groups of first gas delivery grooves 111 are arranged in the width direction of the combustion plate 110, and each group of first gas delivery grooves 111 is distributed along the length direction of the combustion plate 110 and includes a plurality of first gas delivery grooves 111. If n first gas delivery grooves 111 are arranged in the length direction of the combustion plate 110, then n first gas delivery grooves 111 are arranged on each side of the length direction of the second gas delivery groove 112. A plurality of connecting grooves 113 are arranged on the partition wall between each first gas delivery groove 111 and the second gas delivery groove 112.

[0089] Furthermore, in the present embodiment, eight groups of first gas delivery grooves 111 are provided in the width direction of the combustion plate 110, and each group of first gas delivery grooves 111 is distributed along the length direction of the combustion plate 110 and includes three first gas delivery grooves 111, that is, a total of twenty-four first gas delivery grooves 111; three second gas delivery grooves 112 are arranged along the length direction of the combustion plate 110, and are respectively located between the second-third group, the forty-fifth group, and the sixty-seventh group of first gas delivery grooves 111; three first gas delivery grooves 111 are provided on each side of the length direction of the second gas delivery grooves 112; and three connecting grooves 113 are provided on the partition wall between each first gas delivery groove 111 and the second gas delivery groove 112.

[0090] In some embodiments, Figure 2 , Figure 6 , Figure 7 As shown, the combustion plate 110 is further provided with a cooling channel 130 , and the cooling channel 130 is arranged to avoid the first gas delivery groove 111 and the second gas delivery groove 112 .

[0091] In the above embodiment, when the combustion device is turned on, the cooling fluid flowing in the cooling channel 130 can quickly reduce the high temperature generated by the combustion of the combustion plate 110, thereby improving the safety and stability of the combustion plate assembly. At the same time, it can also prevent the combustion plate assembly from flashing back due to excessive temperature and reduce the generation of nitrogen oxides.

[0092] Specifically, Figure 2 , Figure 6 As shown, the water pipes 131 of the cooling channel 130 are arranged along the length direction of the combustion plate 110 , and there are multiple water pipes 131 , which are spaced apart between two adjacent first gas delivery grooves 111 partially along the width direction of the combustion plate 110 .

[0093] Furthermore, if Figure 6 , Figure 7 As shown, in this embodiment, on the basis that three second gas delivery grooves 112 are arranged along the length direction of the combustion plate 110 and are respectively located between the 23rd, 45th, 67th and 8th groups of first gas delivery grooves 111, four water pipes 131 are arranged along the length direction of the combustion plate 110 and are respectively located between the 12nd, 34th, 56th and 78th groups of first gas delivery grooves 111.

[0094] Furthermore, a cooling fluid, such as a coolant, a cooling gas, etc., can flow into the cooling channel 130 .

[0095] In some embodiments, Figure 2 , Figure 8 As shown, the cooling channel 130 includes a water pipe 131 arranged across the combustion plate 110 , and the water pipe 131 can be die-cast in the combustion plate 110 .

[0096] In the above embodiment, the water pipe 131 is preset in the mold, and the water pipe 131 is directly fixed in the combustion plate 110 when the mold is subjected to integral die-casting operation, thereby improving the installation stability of the water pipe 131 and the cooling channel 130 .

[0097] Specifically, if Figure 2 As shown, the cooling channel 130 further includes a water inlet joint 132 and a water outlet joint 133 connected at both sides of the cooling channel 130 .

[0098] In some embodiments, the combustion plate assembly has a first combustion state; in the first combustion state, a mixture of fuel gas and combustion-supporting gas is input from the first gas delivery groove 111 or the second gas delivery groove 112. The combustion plate assembly has a second combustion state; in the second combustion state, fuel gas is input from one of the first gas delivery groove 111 and the second gas delivery groove 112, and combustion-supporting gas is input from the other of the first gas delivery groove 111 and the second gas delivery groove 112.

[0099] In the above embodiment, a first combustion state and a second combustion state of the combustion plate assembly are set to realize a multi-mode combustion operation of the combustion plate assembly.

[0100] Specifically, the first gas source contains one or both of a combustion-supporting gas and a fuel gas, and the second gas source also contains one or both of a combustion-supporting gas and a fuel gas. The specific type of the combustion-supporting gas is not limited, for example, the combustion-supporting gas is oxygen, ozone, chlorine, etc. The specific type of the fuel gas is not limited, for example, the fuel gas is natural gas, coal gas, hydrogen, etc.

[0101] Furthermore, the first gas source can pass one or both of the combustion-supporting gas and the fuel gas to the fire hole 121 through the first gas delivery groove 111. After entering the fire hole 121, the first gas source will enter the combustion chamber 300, and then be ignited by the electric spark in the combustion chamber 300, so as to burn in the combustion chamber 300. The second gas source can pass one or both of the combustion-supporting gas and the fuel gas to the second gas delivery groove 112. After entering the second gas delivery groove 112, the second gas source will further pass into the first gas delivery groove 111. Then it enters the combustion chamber 300 through the fire hole 121, and is ignited by the electric spark in the combustion chamber 300, thereby burning in the combustion chamber 300; wherein, the first gas source or the second gas source can introduce one or both of the combustion-supporting gas and the fuel gas into the corresponding first gas delivery groove 111 or the second gas delivery groove 112 one by one, and can also introduce one or both of the combustion-supporting gas and the fuel gas into the corresponding first gas delivery groove 111 or the second gas delivery groove 112 at the same time, thereby forming the following combustion modes.

[0102] In the first case, when the first gas source can pass the mixed gas of the combustion-supporting gas and the fuel gas through the first gas delivery groove 111, the second gas source does not pass the gas into the second gas delivery groove 112. In this way, the mixed gas that can be passed through the first gas delivery groove 111 by the first gas source passes through the fire hole 121 and enters the combustion chamber 300, and then ignites through the electric spark in the combustion chamber 300, so as to burn in the combustion chamber 300. Since the combustion-supporting gas and the fuel gas in the mixed gas are fully mixed, a more intense combustion reaction will occur after ignition in the combustion chamber 300, and therefore, the first case is defined as a premixed combustion mode.

[0103] Correspondingly, in the second case, when the second gas source introduces a mixture of combustion-supporting gas and fuel gas into the second gas delivery groove 112, the first gas source does not introduce gas into the first gas delivery groove 111.
