[0033] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0034] Embodiment 1

[0035] Please refer to Figure 1 to Figure 6 The embodiment of the present application discloses a gas stove, including a combustion unit 100 and a fan 200. The structure of the gas stove of the present application can also be applied to other combustion devices.

[0036] It should be understood that a gas stove is a device that generates flames by burning fuel gas. After the fuel gas is introduced into the gas stove, the fuel gas is mixed with air to form a mixed gas, and the mixed gas is ignited to form a flame. Therefore, the gas stove needs to be connected to a gas pipeline to input fuel gas into the combustion device, and the combustion device also needs to have an air port for allowing air to enter, so that the air can be mixed with the fuel gas to form a mixed gas.

[0037] The fuel gas input into the gas stove through the gas pipe can be mixed with primary air to form a mixed gas. The primary air is sucked into the ejector pipe 150 during the process of gas being input into the gas stove's ejector pipe 150, so that the primary air and gas are mixed to form a mixed gas. The secondary air is the air that is mixed with the gas again after the primary air and gas are mixed.

[0038] In addition, it should be understood that in a gas stove, both primary air and secondary air serve to make the gas burn more completely. Therefore, when the gas flow rate of the gas stove is constant, the higher the supply of primary air and secondary air, the more completely the gas can burn, thereby making the gas stove have a better combustion effect.

[0039] In the present application, the combustion part 100 is a basic component of the gas stove. The combustion part 100 can provide a mounting base for at least part of other components of the gas stove. The gas pipe can be connected to the combustion part 100 to supply gas to the combustion part 100. The combustion part 100 has a first gas mixing chamber 111 and a second gas mixing chamber 112. It should be understood that the gas in the first gas mixing chamber 111 and the second gas mixing chamber 112 is a mixed gas of gas and air. The gas is input into the combustion part 100 through the gas pipe, and after the primary air is sucked into the combustion part 100, the mixed gas of the gas and the primary air is located in the first gas mixing chamber 111 and the second gas mixing chamber 112 of the combustion part 100. The mixed gas continues to mix in the first gas mixing chamber 111 and the second gas mixing chamber 112 so that the gas and the air are fully mixed. The mixed gas in the first gas mixing chamber 111 and the second gas mixing chamber 112 of the combustion part 100 can eventually be discharged through the fire hole of the combustion part 100 and ignited to form a flame.

[0040] An air passage 113 is also provided in the combustion section 100, and the air passage 113 is configured to be connected to the first air mixing chamber 111 and the second air mixing chamber 112. The air outside the gas stove can enter the air passage 113, and then be input into the first air mixing chamber 111 and the second air mixing chamber 112 respectively through the air passage 113 to replenish air into the first air mixing chamber 111 and the second air mixing chamber 112, so as to further increase the oxygen content in the mixed gas in the first air mixing chamber 111 and the second air mixing chamber 112. Therefore, the air passage 113 in the combustion section 100 of the present application can be used as a passage for replenishing secondary air.

[0041] The combustion part 100 can provide an installation for the fan 200, so that the fan 200 is arranged in the combustion part 100, and the fan 200 can input the air outside the combustion part 100 into the air channel 113, and then input the air from the air channel 113 into the first gas mixing chamber 111 and the second gas mixing chamber 112, respectively, so that the air content of the mixed gas in the first gas mixing chamber 111 and the second gas mixing chamber 112 is sufficient. The fan 200 can accelerate the air outside the combustion part 100 to flow into the air channel 113 of the combustion part 100, and then accelerate the air to flow into the first gas mixing chamber 111 and the second gas mixing chamber 112 of the combustion part 100, so as to achieve the purpose of making the secondary air replenishment efficiency of the gas stove of the present application higher.

[0042] The fan 200 is installed on the combustion part 100, so that the gas stove of the present application does not need to be provided with a structure for installing the fan 200 at other parts, so as to achieve the purpose of simplifying the gas stove of the present application. In addition, since the fan 200 is provided on the combustion part 100, the fan 200 can be provided closer to the air passage 113 of the combustion part 100, so that the fan 200 can more efficiently input the air outside the gas stove into the air passage 113 of the combustion part 100 after sucking in the air, and then more efficiently input the air into the first air mixing chamber 111 and the second air mixing chamber 112 of the combustion part 100.

[0043] In the gas stove disclosed in the embodiment of the present application, the air passage 113 provided in the combustion part 100 is communicated with the first gas mixing chamber 111 and the second gas mixing chamber 112 respectively, so that the air outside the combustion part 100 can be input into the first gas mixing chamber 111 and the second gas mixing chamber 112 respectively through the air passage 113, so as to further improve the oxygen content in the mixed gas in the first gas mixing chamber 111 and the second gas mixing chamber 112. The combustion part 100 can provide an installation base for the fan 200, so that the fan 200 can be arranged in the combustion part 100, thereby making the fan 200 easy to install. The fan 200 can accelerate the air outside the combustion part 100 to flow into the air passage 113, and accelerate the air flow to the first gas mixing chamber 111 and the second gas mixing chamber 112, so as to improve the secondary air replenishment efficiency of the gas stove of the present application.

[0044] In some embodiments, in order to enable the air channel 113 in the combustion portion 100 of the present application to more efficiently input air into the first mixing chamber 111 and the second mixing chamber 112 respectively, the second mixing chamber 112 of the present application can be configured to surround the first mixing chamber 111. Therefore, the flame formed by the ignition of the mixed gas in the first mixing chamber 111 and the second mixing chamber 112 includes a central flame and an outer flame surrounding the central flame. In this way, the flame formed by the gas stove of the present application can be more evenly distributed, so that the heated component can be heated evenly.

[0045] The air passage 113 in the combustion part 100 can be arranged between the first air mixing chamber 111 and the second air mixing chamber 112. Therefore, the second air mixing chamber 112 can be arranged around the first air mixing chamber 111 at intervals, so that there is a space between the first air mixing chamber 111 and the second air mixing chamber 112 to arrange the air passage 113. When the air passage 113 is arranged between the first air mixing chamber 111 and the second air mixing chamber 112, the air passage 113 can be arranged adjacent to the first air mixing chamber 111 and the second air mixing chamber 112 at the same time, so that the distance between the air passage 113 and the first air mixing chamber 111 and the second air mixing chamber 112 is relatively small, so that the air in the air passage 113 can reach the first air mixing chamber 111 and the second air mixing chamber 112 after a shorter distance, thereby making the secondary air supply efficiency of the gas stove of the present application higher.

[0046] In addition, it should be understood that when the air is heated, its pressure can increase, thereby making the air more active. In the present application, the gas in the first mixing chamber 111 and the second mixing chamber 112 can be discharged through the fire holes and ignited to form flames, thereby making the first mixing chamber 111 and the second mixing chamber 112 have a higher temperature. In this way, the temperature of the air in the air channel 113 adjacent to the first mixing chamber 111 and the second mixing chamber 112 is relatively higher, thereby making the flow rate of the air in the air channel 113 faster, and the air in the air channel 113 can flow into the first mixing chamber 111 and the second mixing chamber 112 more quickly.

[0047] In some embodiments, it should be understood that the larger the space of the air channel 113 in the combustion part 100, the more air the air channel 113 can accommodate, so that the amount of air supplied to the first air mixing chamber 111 and the second air mixing chamber 112 through the air channel 113 can be more sufficient. Therefore, the air channel 113 of the combustion part 100 of the present application can be arranged to surround the first air mixing chamber 111, so that the air channel 113 is distributed along the circumference of the first air mixing chamber 111, so that the space of the air channel 113 is relatively large.

[0048] Specifically, the second air mixing chamber 112 in the combustion part 100 can be arranged to surround the first air mixing chamber 111, and each circumferential portion of the second air mixing chamber 112 is arranged to be spaced apart from the first air mixing chamber 111, so that there is enough space between the first air mixing chamber 111 and the second air mixing chamber 112 to set the air channel 113. After the air channel 113 is surrounded by the first air mixing chamber 111, the second air mixing chamber 112 also surrounds the air channel 113.

[0049] In some embodiments, it should be understood that since the air channel 113 of the combustion section 100 is connected to the first air mixing chamber 111 and the second air mixing chamber 112, the air channel 113 has a first air outlet 1132 and a second air outlet 1133, and the air in the air channel 113 is input into the first air mixing chamber 111 through the first air outlet 1132, and the air in the air channel 113 is input into the second air mixing chamber 112 through the second air outlet 1133. When the air channel 113 of the combustion section 100 is surrounded by the first air mixing chamber 111 and the second air mixing chamber 112, in order to allow the air in the air channel 113 to be more efficiently input into the first air mixing chamber 111 and the second air mixing chamber 112, the first air outlet 1132 and the second air outlet 1133 of the air channel 113 can be set to be multiple, and the multiple first air outlets 1132 and the multiple second air outlets 1133 are all distributed along the circumference of the air channel 113, so that the air in the air channel 113 can be input into the first air mixing chamber 111 and the second air mixing chamber 112 from multiple directions.

[0050] In addition, it should be noted that the first air outlet 1132 and the second air outlet 1133 in the air channel 113 can also be set as strip holes arranged along the circumference of the air channel 113, so that the openings of the first air outlet 1132 and the second air outlet 1133 can be relatively larger, so that the air in the air channel 113 can be more efficiently input into the first air mixing chamber 111 and the second air mixing chamber 112 through the first air outlet 1132 and the second air outlet 1133.

[0051] In some embodiments, in order to provide the combustion part 100 of the present application with the first gas mixing chamber 111, the second gas mixing chamber 112 and the air passage 113, the combustion part 100 of the present application can be configured to include a burner head 110, an outer fire cover 130, an inner fire cover 120 and an induced draft cover 140, wherein the outer fire cover 130, the inner fire cover 120 and the induced draft cover 140 are all arranged on the burner head 110, and the burner head 110 is provided with a plurality of groove structures, and the plurality of groove structures are arranged corresponding to the inner fire cover 120, the outer fire cover 130 and the induced draft cover 140, so that the inner fire cover 120 A first gas mixing chamber 111 is formed between the inner fire cover 120 and the burner head 110, a second gas mixing chamber 112 is formed between the outer fire cover 130 and the burner head 110, an air passage 113 is formed between the draft cover 140 and the burner head 110, an inner fire hole 121 and an outer fire hole 131 are respectively provided on the inner fire cover 120 and the outer fire cover 130, the mixed gas in the first gas mixing chamber 111 can be discharged through the inner fire hole 121 of the inner fire cover 120 to be ignited, and the mixed gas in the second gas mixing chamber 112 can be discharged through the outer fire hole 131 of the outer fire cover 130 to be ignited.

[0052] In addition, it should be understood that the outer fire cover 130, the inner fire cover 120 and the induced draft cover 140 are arranged on the burner head 110, so that the burner head 110 can provide an installation basis for the inner fire cover 120, the outer fire cover 130 and the induced draft cover 140. Specifically, the inner fire cover 120, the outer fire cover 130 and the induced draft cover 140 can be directly placed on the burner head 110, so that the inner fire cover 120, the outer fire cover 130 and the induced draft cover 140 can also be conveniently taken from the burner head 110, so that the burner head 110, the inner fire cover 120, the outer fire cover 130 and the induced draft cover 140 are easy to clean. The side walls of the multiple groove structures opened on the burner head 110 can be used to support the inner fire cover 120, the outer fire cover 130 and the induced draft cover 140.

[0053] Specifically, the outer fire cover 130 of the combustion part 100 can be arranged to surround the inner fire cover 120, the draft cover 140 is arranged between the inner fire cover 120 and the outer fire cover 130, and the outer fire cover 130 is arranged to surround the draft cover 140, and the draft cover 140 is arranged to surround the inner fire cover 120.

[0054] In some embodiments, in order to reduce the difficulty of preparing the draft cover 140 of the present application and save materials for the draft cover 140, after the draft cover 140 is set on the burner head 110, the draft cover 140, the burner head 110 and the side walls of the inner fire cover 120 are jointly formed to form the air channel 113. Specifically, there is no need to additionally set a cover body structure on the side of the draft cover 140 facing the inner fire cover 120, so that the outer wall of the inner fire cover 120 can be used as the inner wall of the air channel 113, thereby achieving the purpose of saving materials for the draft cover 140. Of course, it should be noted that, under the above-mentioned induced draft cover 140 setting structure, the inner fire hole 121 of the inner fire cover 120 should be set outside the air passage 113, so that when the outer wall of the inner fire cover 120 serves as the inner wall of the air passage 113, the induced draft cover 140 will not surround the inner fire hole 121 of the inner fire cover 120 inside, so that the mixed gas discharged from the inner fire hole 121 of the inner fire cover 120 can burn smoothly. Specifically, the inner fire cover 120 can be set on the side wall of the inner fire cover 120 facing away from the induced draft cover 140.

[0055] Of course, it should be understood that in other embodiments, the draft cover 140 of the present application can also be set up to enclose the side walls of the stove head 110 and the outer fire cover 130 to form the air channel 113. Specifically, the side of the draft cover 140 facing the outer fire cover 130 does not need to be additionally provided with a cover structure, so that the inner side wall of the outer fire cover 130 can be used as the inner wall of the air channel 113, thereby also achieving the purpose of saving the material of the draft cover 140. Of course, it should be noted that under the above-mentioned draft cover 140 setting structure, the outer fire hole 131 of the outer fire cover 130 can be set on the side wall of the outer fire cover 130 facing away from the draft cover 140. In this way, when the inner side wall of the outer fire cover 130 is used as the inner wall of the air channel 113, the draft cover 140 will not enclose the outer fire hole 131 of the outer fire cover 130 inside, so that the mixed gas discharged from the outer fire hole 131 of the outer fire cover 130 can burn smoothly.

[0056] In addition, in other embodiments, the draft cover 140 of the present application can also be configured as a cover plate mounted between the outer fire cover 130 and the inner fire cover 120, so that the draft cover 140, the outer wall of the inner fire cover 120, the inner wall of the outer fire cover 130 and the burner head 110 are jointly arranged to form an air passage 113, thereby saving the material of the draft cover 140 to the greatest extent.

[0057] In some embodiments, in order to enable the air channel 113 in the combustion section 100 of the present application to be connected with the first mixing chamber 111, the draft cover 140 of the present application can be configured to cover at least a portion of the inner fire cover 120. Specifically, the inner top wall of the draft cover 140 is arranged opposite to the top of the inner fire cover 120, and there is a certain gap between the inner top wall of the draft cover 140 and the top of the inner fire cover 120, and the gap can constitute a first air outlet 1132. The air in the air channel 113 can be discharged to the outside of the air channel 113 through the first air outlet 1132, and because the opening of the first air outlet 1132 is toward the side of the inner fire cover 120, the air discharged through the first air outlet 1132 of the air channel 113 can act on the inner fire cover 120 to supplement secondary air for the flame burning at the inner fire cover 120.

[0058] By arranging the first air outlet 1132 on the portion of the draft cover 140 that is arranged on the inner fire cover 120, and making the first air outlet 1132 located between the draft cover 140 and the inner fire cover 120, it is possible to avoid the need to separately open the first air outlet 1132 on the draft cover 140. The air discharged through the first air outlet 1132 can flow along the outer wall of the inner fire cover 120 under the effect of the wall attachment effect. Since the inner fire hole 121 of the inner fire cover 120 is opened on the surface of the inner fire cover 120, the air flowing along the outer wall of the inner fire cover 120 can more easily flow to the position of the inner fire hole 121 of the inner fire cover 120, so that the air discharged through the first air outlet 1132 can be better supplemented to the inner fire cover 120, so that the fire power of the flame generated at the inner fire cover 120 is more sufficient.

[0059] In addition, it should be understood that when the gap between the draft cover 140 and the inner fire cover 120 forms the first air outlet 1132, in order to make the opening of the first air outlet 1132 larger, the circumferential bottom wall of the draft cover 140 and the circumferential top wall of the inner fire cover 120 can be provided with a gap, and the spacing of the gaps can be kept consistent. In this way, the first air outlet 1132 can be distributed along the circumference of the draft cover 140, and the opening sizes of various parts of the first air outlet 1132 in the circumference of the draft cover 140 are consistent, thereby achieving the purpose of uniformly replenishing secondary air to various circumferential parts of the inner fire cover 120.

[0060] In some embodiments, in order to make the air passage 113 of the present application communicate with the second gas mixing chamber 112, the second air outlet 1133 can be opened on the side wall of the induced draft cover 140 facing the outer fire cover 130 when the induced draft cover 140 surrounds the inner fire cover 120 and the induced draft cover 140 is surrounded by the outer fire cover 130, so that the opening of the second air outlet 1133 can face the outer fire cover 130, and because the outer fire cover 130 surrounds the induced draft cover 140 at intervals, the secondary air in the air passage 113 of the combustion part 100 can flow to the outer fire cover 130 through the second air outlet 1133 on the induced draft cover 140. Since the outer fire cover 130 is provided with an outer fire hole 131, the secondary air flowing to the outer fire cover 130 through the air passage 113 of the combustion part 100 can supplement air to the flame generated by the outer fire cover 130, thereby making the flame force of the flame at the outer fire cover 130 stronger.

[0061] It should be understood that the mixed gas in the second gas mixing chamber 112 of the combustion part 100 of the present application can be sprayed through the fire hole of the outer fire cover 130. Therefore, when the secondary air in the air channel 113 can directly supplement the secondary air to the outer fire hole 131 of the outer fire cover 130, the gas in the second gas mixing chamber 112 of the combustion part 100 can be burned more fully. Specifically, the outer fire hole 131 of the outer fire cover 130 can be arranged on the side wall of the outer fire cover 130 facing the induced draft cover 140, so that the second air outlet 1133 of the induced draft cover 140 and the outer fire hole 131 of the outer fire cover 130 can be arranged opposite to each other, thereby achieving the purpose of reducing the distance between the second air outlet 1133 of the induced draft cover 140 and the outer fire hole 131 of the outer fire cover 130, and further allowing the secondary air discharged through the second air outlet 1133 of the induced draft cover 140 to reach the outer fire hole 131 of the outer fire cover 130 more quickly. The number of the second air outlets 1133 on the air induction cover 140 may be multiple, and the multiple second air outlets 1133 may be arranged to be spaced apart along the circumference of the air induction cover 140 .

[0062] In addition, it should be noted that the gas in the second mixing chamber 112 of the combustion section 100 is ignited after being discharged through the outer fire hole 131 of the outer fire cover 130. Therefore, in order to make the secondary air have a better combustion-supporting effect on the flame at the outer fire cover 130, it can be achieved by adding secondary air to the root of the flame of the outer fire cover 130. The position of the outer fire hole 131 of the outer fire cover 130 is the root position of the flame at the outer fire cover 130.

[0063] In the present application, the height of the second air outlet 1133 of the draft cover 140 can be set to be no higher than the outer fire hole 131 of the outer fire cover 130, so that the secondary air discharged through the second air outlet 1133 of the draft cover 140 can be replenished to the outer fire hole 131 of the outer fire cover 130, and then the secondary air can be replenished to the flame root at the outer fire cover 130.

[0064] Specifically, the second air outlet 1133 of the draft cover 140 of the present application may form a projection area on the outer fire cover 130 in the direction toward the outer fire cover 130, and the projection area located on the outer fire cover 130 is closer to the stove head 110 than the outer fire hole 131 on the outer fire cover 130, so that the height of the second air outlet 1133 of the draft cover 140 can be lower than the outer fire hole 131 of the outer fire cover 130. After the second air outlet 1133 of the draft cover 140 discharges the secondary air, the initial position of the secondary air flow is lower than the outer fire hole 131 of the outer fire cover 130. Since the gas stove has a high temperature when working, the temperature of the secondary air can be increased accordingly, so the secondary air flow can naturally rise. In addition, since the air outlet of the draft cover 140 is toward the outer fire cover 130, the secondary air discharged through the second air outlet 1133 of the draft cover 140 has a speed of flowing toward the outer fire cover 130 and a natural rising speed, so that the secondary air discharged from the second air outlet 1133 of the draft cover 140 can flow toward the outer fire hole 131 of the outer fire cover 130, thereby replenishing the secondary air for the root of the flame generated by the outer fire cover 130.

[0065] In some embodiments, in order to make it more convenient to install the fan 200 of the present application on the combustion part 100, the fan 200 of the present application can be arranged at one side of the bottom of the combustion part 100. Specifically, the fan 200 can be arranged at the side of the burner 110 facing away from the draft cover 140, so that the fan 200 is located at the bottom of the burner 110. It should be understood that when the gas stove is installed on the stove, part of the burner 110 is located below the panel of the gas stove, and accordingly, the connection between the gas pipe and the burner 110 is also located below the panel, so as to achieve the purpose of hiding the connection between the gas pipe and the burner 110, and further to protect the connection between the gas pipe and the burner 110. In addition, other parts of the gas stove can also be arranged below the panel of the gas stove.

[0066] When the fan 200 is disposed on the side of the burner 110 facing away from the draft cover 140 , that is, the fan 200 is disposed below the panel of the gas stove, the fan 200 can be hidden inside the gas stove, thereby achieving the purpose of protecting the fan 200 .

[0067] In the present application, the air passage 113 of the combustion section 100 is provided with an air inlet 1131. The air outside the air passage 113 can be input into the air passage 113 through the air inlet 1131, and then can be input into the first air mixing chamber 111 and the second air mixing chamber 112 respectively through the first air outlet 1132 and the second air outlet 1133. Therefore, in order to make it easier for the fan 200 to input secondary air into the air passage 113 through the air inlet 1131 of the air passage 113, the air inlet 1131 of the air passage 113 can be set on the outer wall of the side of the burner 110 facing away from the draft cover 140. Specifically, the air channel 113 of the combustion section 100 in the present application is formed by the groove on the burner head 110 and the draft cover 140. Therefore, the air inlet 1131 of the air channel 113 can be set on the first side of the burner head 110 facing away from the draft cover 140, so that the air outlet of the air channel 113 is located on the bottom side of the combustion section 100.

[0068] When the fan 200 and the air inlet 1131 of the air channel 113 are both located at the bottom side of the combustion section 100 , the air outlet side of the fan 200 can be set to be opposite to the air inlet 1131 of the air channel 113 so that the fan 200 can directly input secondary air into the air channel 113 .

[0069] In some embodiments, in order to further facilitate the installation of the fan 200 on the combustion part 100, the gas stove of the present application may further be provided with an air induction shell 300, and the air induction shell 300 may be provided to be connected to the burner 110. An air induction channel 310 may be provided in the air induction shell 300, and the air induction channel 310 of the burner 110 is communicated with the air inlet 1131 of the burner 110. The fan 200 may be provided on the air induction shell 300, and the air outlet side of the fan 200 is communicated with the air induction channel 310 of the air induction shell 300, so that the fan 200 may input secondary air into the air induction channel 310 of the air induction shell 300, and the secondary air is input into the air channel 113 of the combustion part 100 through the air induction channel 310, and then input into the first air mixing chamber 111 and the second air mixing chamber 112 through the first air outlet 1132 and the second air outlet 1133 respectively.

[0070] Specifically, the induced draft housing 300 may be disposed at one side of the bottom of the combustion unit 100, and the fan 200 may be disposed at the side of the induced draft housing 300 facing away from the burner 110, so that a certain distance may be provided between the fan 200 and the burner 110. It should be understood that a large amount of heat is generated during operation of the gas stove, so that the temperature of the burner 110 is relatively high. Therefore, by providing the induced draft housing 300, the distance between the fan 200 and the burner 110 may be increased, so that the fan 200 is relatively less affected by the high temperature of the burner 110, thereby achieving the purpose of protecting the fan 200.
