Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0069] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0070] The following is combined with Figures 1-10 The following describes embodiments of the present invention.

[0071] According to embodiments of the present invention, in one aspect, 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 disposed opposite to each other. The combustion plate 110 is provided with a plurality of first gas delivery grooves 111 penetrating the first surface and the second surface. The air inlet of the first gas delivery groove 111 is used to communicate with a first gas source. The flame hole plate 120 covers the first surface. The flame hole plate 120 is provided with a plurality of flame hole groups. Each flame hole group includes a plurality of flame holes 121. Each flame hole group is connected to a 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 flame holes 121.

[0073] In the above embodiment, a flame hole plate 120 is added to the combustion plate 110, and flame holes 121 communicating with the first gas supply groove 111 of the combustion plate 110 are provided on the flame hole plate 120. In this way, the first gas supply groove 111 for gas supply and the flame holes 121 for flame combustion are designed separately, and the combustion plate 110 and the flame hole plate 120 can be cast separately. The flame hole plate 120 is provided with multiple sets of flame holes, and the multiple flame holes 121 of each set of flame holes are connected to a first gas supply groove 111, so that a first gas supply groove 111 can supply gas to multiple flame holes 121 for flame combustion. While ensuring the small size design of the flame holes 121, the first gas supply groove 111 can be provided with a relatively large gas supply channel, thereby reducing the manufacturing difficulty of the combustion plate 110.

[0074] Meanwhile, the combustion plate 110 and the flame perforation plate 120 are easy to assemble and disassemble, which is beneficial for future maintenance and replacement. Furthermore, the combustion plate 110 and the flame perforation plate 120 can be manufactured separately, simplifying the process and saving costs. In addition, the combustion plate assembly provided in this embodiment has a simple and compact structure with high space utilization, which is conducive to the miniaturization of gas devices and equipment.

[0075] Specifically, such as Figure 2 , Figure 3 As shown, the first surface of the combustion plate 110 is the side closest to the flame hole plate 120, and the second surface of the combustion plate 110 is the side furthest from the flame hole plate 120. The flame hole plate 120 covers the first surface of the combustion plate 110 and is fixedly connected by several fasteners. The combustion plate 110 has multiple first gas delivery slots 111, and the flame hole plate 120 has multiple sets of flame holes 121 corresponding to each combustion plate 110. Each set of flame holes 121 includes at least two adjacent flame holes 121. After the flame hole plate 120 is covered on the first surface of the combustion plate 110, the first gas delivery slots 111 corresponding to each set of flame holes 121 are connected. The first gas source is supplied to the inlet of the first gas delivery slot 111 and discharged from the outlet of the first gas delivery slot 111, thus reaching the corresponding set of flame holes 121. In the combustion chamber 300, it is ignited by an electric spark and then undergoes flame combustion.

[0076] Furthermore, the combustion plate assembly provided in this embodiment changes the design of one gas supply channel corresponding to one flame hole in related technologies, and adopts a design of one first gas supply groove 111 corresponding to multiple flame holes 121. The first gas supply groove 111 on the combustion plate 110 is only used for gas supply, realizing that gas is supplied through the first gas supply groove 111 to the corresponding set of multiple flame holes 121 for flame combustion. More specifically, as Figure 3 , Figure 4 As shown, this embodiment optimizes multiple small gas delivery channels into 24 relatively large first gas delivery slots 111, which is equivalent to increasing the area of ​​a single gas delivery channel several times. The increased size of the first gas delivery slots 111 reduces the processing difficulty of die casting, thereby reducing the manufacturing difficulty of the combustion plate 110. At the same time, the flame hole plate 120 itself is designed as a thin plate structure, which greatly reduces the processing difficulty even if multiple dense flame holes 121 need to be processed on it.

[0077] Furthermore, in this embodiment, the multiple adjacent flame holes 121 in each group of flame holes are all designed as micro-holes. This arrangement makes it difficult for the flame to propagate downwards when burning on the upper surface of the flame holes 121, thus avoiding backfire problems. Figure 3 , Figure 4 As shown, each group of flame holes 121 includes twenty flame holes 121. That is, in this embodiment, one first gas supply channel 111 supplies gas to the twenty flame holes 121 for flame combustion. This embodiment does not limit the shape of the flame holes 121; the flame holes 121 can be set to rectangular, triangular, circular, or other shapes.

[0078] Furthermore, such as Figure 2 As shown, the first surface of the combustion plate 110 is provided with a positioning post 114, and the flame hole plate 120 is provided with a positioning groove 122 corresponding to the positioning post 114. When the combustion plate 110 and the flame hole plate 120 are assembled, the positioning post 114 and the positioning groove 122 are aligned and inserted.

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

[0080] In some embodiments, such as Figure 3 , Figure 5 As shown, the combustion plate 110 is also provided with a second gas delivery channel 112 that is connected to the first gas delivery channel 111. The second gas delivery channel 112 is used to connect to the second gas source.

[0081] In the above embodiment, the combustion plate 110 is also provided with a second gas supply channel 112 that is connected to the first gas supply channel 111 and can supply a second gas source, thereby realizing the adjustment of the combustion plate assembly to various firepower operating ranges.

[0082] Specifically, such as Figure 2 , Figure 3, Figure 5 As shown, a first gas source is introduced into the ignition port 121 through the first gas supply channel 111. After entering the ignition port 121, the first gas source enters the combustion chamber 300 and is ignited by an electric spark in the combustion chamber 300, thus burning in the combustion chamber 300. A second gas source is introduced into the second gas supply channel 112. After entering the second gas supply channel 112, the second gas source is further introduced into the first gas supply channel 111, and then enters the combustion chamber 300 through the ignition port 121, where it is ignited by an electric spark, thus burning in the combustion chamber 300. This realizes the combustion mode of the dual combustion system, allowing for the adjustment of various firepower operating ranges.

[0083] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the second gas delivery groove 112 is formed by the indentation of the first surface; the combustion plate 110 is also provided with a connecting groove 113 formed by the indentation of the first surface, 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 is closed on the first surface, it covers the second gas delivery groove 112 and the connecting groove 113.

[0084] In the above embodiment, the first gas delivery channel 111 and the second gas delivery channel 112 are connected by a connecting channel 113, thereby enabling gas delivery from the second gas delivery channel 112 to the first gas delivery channel 111 through the connecting channel 113; when the flame plate 120 is closed on the first surface, it covers the second gas delivery channel 112 and the connecting channel 113, thereby achieving a closed arrangement on the gas flow path of the second gas delivery channel 112-connecting channel 113-first gas delivery channel 111, and preventing gas from escaping from the first surface of the combustion plate 110.

[0085] Specifically, such as Figure 6 , Figure 7 , Figure 8 As shown, since the second gas delivery groove 112 and the connecting groove 113 are both semi-enclosed groove structures formed by the indentation of the first surface of the combustion plate 110, when the flame hole plate 120 is covered on 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 flame hole plate 120 without flame holes 121, thereby achieving a 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, such as Figure 3 , Figure 5As 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 arranged adjacent to each other on both sides of the length direction of the second gas delivery groove 112, 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, a connecting groove 113 is provided directly 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, such as Figure 3 , Figure 5 As shown, the first gas delivery grooves 111 are evenly spaced and arranged, and multiple sets of first gas delivery grooves 111 are provided in the width direction of the combustion plate 110. Each set of first gas delivery grooves 111 is distributed along the length direction of the combustion plate 110 and includes multiple first gas delivery grooves 111. If n first gas delivery grooves 111 are provided in the length direction of the combustion plate 110, then n first gas delivery grooves 111 are provided on each side of the length direction of the second gas delivery groove 112. Multiple connecting grooves 113 are provided on the partition wall between each first gas delivery groove 111 and the second gas delivery groove 112.

[0089] Furthermore, in this embodiment, eight groups of first gas delivery grooves 111 are provided in the width direction of the combustion plate 110. 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 and third groups, the fourth and fifth groups, and the sixth and seventh groups 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. 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, such as Figure 2 , Figure 6 , Figure 7 As shown, the combustion plate 110 is also provided with a cooling channel 130, and the cooling channel 130 is arranged to avoid the first gas delivery channel 111 and the second gas delivery channel 112.

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

[0092] Specifically, such as Figure 2 , Figure 6As shown, the water supply pipes 131 of the cooling channel 130 are arranged along the length of the combustion plate 110, and multiple pipes are provided. The multiple water supply pipes 131 are spaced apart between two first gas supply slots 111 that are partially adjacent along the width of the combustion plate 110.

[0093] Furthermore, such as Figure 6 , Figure 7 As shown, in this embodiment, three second gas delivery channels 112 are arranged along the length of the combustion plate 110 and are respectively located between the first gas delivery channels 111 of the second and third groups, the fourth and fifth groups, and the sixth and seventh groups. Four water delivery pipes 131 are arranged along the length of the combustion plate 110 and are respectively located between the first gas delivery channels 111 of the first and second groups, the third and fourth groups, the fifth and sixth groups, and the seventh and eighth groups.

[0094] Furthermore, cooling fluids, such as coolant or cooling gas, can be introduced into the cooling channel 130.

[0095] In some embodiments, such as Figure 2 , Figure 8 As shown, the cooling channel 130 includes a water pipe 131 that spans the combustion plate 110 and can be die-cast into the combustion plate 110.

[0096] In the above embodiment, the water supply pipe 131 is pre-set in the mold, and the water supply pipe 131 is directly fixed in the combustion plate 110 when the mold is being die-cast, thereby improving the installation stability of the water supply pipe 131 and the cooling channel 130.

[0097] Specifically, such as Figure 2 As shown, the cooling channel 130 also includes an inlet connector 132 and an outlet connector 133 connected to 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 through a first gas supply channel 111 or a second gas supply channel 112. The combustion plate assembly has a second combustion state; in the second combustion state, fuel gas is input through one of the first gas supply channel 111 and the second gas supply channel 112, and combustion-supporting gas is input through the other of the first gas supply channel 111 and the second gas supply channel 112.

[0099] In the above embodiments, a first combustion state and a second combustion state of the combustion plate assembly are set to realize 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 combustion-supporting gas is not limited; for example, it could be oxygen, ozone, or chlorine. The specific type of fuel gas is also not limited; for example, it could be natural gas, coal gas, or hydrogen.

[0101] Furthermore, the first gas source can supply one or both of the combustion-supporting gas and the fuel gas to the ignition port 121 through the first gas supply channel 111. After entering the ignition port 121, the first gas source enters the combustion chamber 300 and is ignited by an electric spark within the combustion chamber 300, thus burning in the combustion chamber 300. The second gas source can supply one or both of the combustion-supporting gas and the fuel gas to the second gas supply channel 112. After entering the second gas supply channel 112, the second gas source further enters the first gas supply channel 111. Then it enters the combustion chamber 300 through the ignition hole 121 and is ignited by the electric spark in the combustion chamber 300, thus burning in the combustion chamber 300; wherein, the first gas source or the second gas source can successively introduce one or both of the combustion-supporting gas and the fuel gas into the corresponding first gas supply channel 111 or the second gas supply channel 112, or can simultaneously introduce one or both of the combustion-supporting gas and the fuel gas into the corresponding first gas supply channel 111 or the second gas supply channel 112, thereby forming the following combustion modes.

[0102] In the first scenario, when the first gas source can supply a mixture of combustion-supporting gas and fuel gas through the first gas supply channel 111, the second gas source does not supply gas to the second gas supply channel 112. Thus, the mixture supplied by the first gas source through the first gas supply channel 111 passes through the ignition port 121 and enters the combustion chamber 300, where it is ignited by an electric spark, resulting in combustion within the combustion chamber 300. Because the combustion-supporting gas and fuel gas are thoroughly mixed in the mixture, the combustion reaction is relatively vigorous after ignition in the combustion chamber 300. Therefore, the first scenario 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 channel 112, the first gas source does not introduce gas into the first gas delivery channel 111. The second case also corresponds to the premixed combustion mode.

[0104] In the third scenario, when the first gas source can supply fuel gas through the first gas delivery channel 111, the second gas source supplies combustion-supporting gas into the second gas delivery channel 112. In this way, the fuel gas and combustion-supporting gas mix and flow out together from the ignition port 121, and are ignited by an electric spark within the combustion chamber 300, resulting in a relatively stable combustion reaction within the combustion chamber 300. Therefore, the third scenario is defined as a diffusion combustion mode.

[0105] Correspondingly, in the fourth case, when the second gas source introduces fuel gas into the second gas delivery channel 112, the first gas source can introduce combustion-supporting gas through the first gas delivery channel 111.
