However, due to the shortage of domestic electricity and the influence of power transmission and distribution lines, especially the power of urban residents' transmission and distribution lines entering the home. The power of electric stoves cannot be too large. Generally, the maximum power of a single burner is only designed to be within 2.5 kilowatts. Within this power range, cooking Chinese dishes is not enough, and the taste of the cooked dishes is also poor. Therefore, induction cookers and electric ceramic cookers are greatly restricted in cooking Chinese food. Therefore, in terms of gas stoves, the national standard single burner power is ≥3.5 kilowatts, and the first-level energy efficiency thermal efficiency is stipulated to be above 63%. To meet the conditions for Chinese food cooking, high firepower and high power are required to meet the cooking and heating requirements of Chinese food. Electric stoves cannot replace gas stoves due to power limitations.

[0053] The present invention has at least the following beneficial effects:

[0054] According to a gas stove in the present invention, it includes: a heat-conducting panel, a burner, a bottom wall, an annular side wall and a blocking and diverting assembly. The heat-conducting panel is arranged above the burner, and the bottom wall is arranged outside the burner and directly facing the heat-conducting panel, so that the hot smoke generated by the burner is diffused to the periphery from the gap formed between the heat-conducting panel and the bottom wall, and the top of the annular side wall is connected to the heat-conducting panel, and the bottom of the annular side wall is connected to the bottom wall. Based on this design, the combustion area of ​​the gas stove is located below the heat-conducting panel, and the pot is directly placed on the heat-conducting panel. The infrared heat energy generated by the burner is transferred to the pot through the heat-conducting panel to achieve its heating. Compared with the prior art, the existing pot support exposed on the upper surface of the stove can be eliminated, so that the upper surface of the stove becomes neat, easy to clean, and has stronger wind resistance for small fire and micro fire. On the other hand, during the cooking process, the pot can be placed flat on the heat-conducting panel, which overcomes the defect of the prior art that the pot is placed on the elevated pot support, and prevents unsafe accidents from happening. Since there is no need for a pot stand, the panel surface space is no longer occupied. When the user is not using the burner to heat and cook dishes, the panel surface space can be used for other purposes, such as placing kitchen equipment or processing food in the panel area. In addition, the upper surface of the cooker is neater and smoother, making the entire cooker and panel easier to clean.

[0055] At the same time, since the burner, bottom wall, and annular side wall are located below the heat-conducting panel, compared with the open-air combustion in the prior art, the combustion area is not affected by wind in the air, etc., and the combustion is more stable, especially when the fire is small or micro, the combustion is more stable and safer.

[0056] Moreover, in the prior art, the waste gas generated by the combustion of the gas stove can only be directly discharged into the kitchen, and a part of the waste gas is sucked away together with the oil smoke through the range hood, but a large amount of waste gas still directly diffuses into the kitchen, and harmful substances such as carbon monoxide and nitrogen oxides in the waste gas can damage human health. In the present invention, the waste gas generated by the combustion is discharged through the exhaust port connected to the exhaust pipe, and can also be directly discharged into the kitchen, and can also be fully collected through the pipe and discharged to the outside of the kitchen. When the waste gas is discharged outdoors, it can avoid polluting the indoor environment and harming human health.

[0057] Moreover, in the present invention, the blocking and diverting assembly is arranged in the spacing, and is used to block and divert the hot flue gas diffused to the blocking and diverting assembly. In the area located outside the blocking and diverting assembly, the bottom wall and / or the annular side wall are provided with a smoke exhaust port; a smoke exhaust channel is formed between the blocking and diverting assembly and the inner surface of the annular side wall, and is used to guide the hot flue gas blocked and diverted by the blocking and diverting assembly to the smoke exhaust port. Based on this design, in the process of the high-temperature hot flue gas generated by the burner burning from the combustion surface of the burner flowing to the smoke exhaust port, the blocking and diverting assembly produces a blocking and diverting effect on the hot flue gas, so that the process of the hot flue gas flowing to the smoke exhaust port is delayed and a turbulent effect is formed, so that the hot flue gas contacts the heat-conducting panel and / or the blocking and diverting assembly for a longer period of time to fully release and transfer heat energy, and the hot flue gas and the radiated infrared rays that form the turbulent effect are repeatedly refracted in the spacing, and then radiate and transfer heat energy from the heat-conducting panel in a directional manner, thereby significantly improving the infrared heat energy radiation effect above the heat-conducting panel, and significantly improving the thermal efficiency of the fully enclosed gas cooker.

[0079] Specific implementation party

[0080] Hereinafter, various embodiments of the present invention will be described more fully. The present invention may have various embodiments, and adjustments and changes may be made therein. However, it should be understood that there is no intention to limit the various embodiments of the present invention to the specific embodiments disclosed herein, but the present invention should be understood to cover all adjustments, equivalents and / or alternatives falling within the spirit and scope of the various embodiments of the present invention.

[0081] Example 1

[0082] like Figure 1-Figure 9 As shown, this embodiment provides a gas cooker, comprising: a heat-conducting panel 2, a burner 12, a bottom wall 9, an annular side wall 8 and a blocking and diverting assembly. The heat-conducting panel 2 is arranged above the burner 12, and the bottom wall 9 is arranged outside the burner 12 and directly facing the heat-conducting panel 2, so that the hot flue gas generated by the burner 12 is diffused to the periphery from the gap formed between the heat-conducting panel 2 and the bottom wall 9, the top of the annular side wall 8 is butted against the heat-conducting panel 2, and the bottom of the annular side wall 8 is connected to the bottom wall 9. Preferably, it also includes a base shell assembly 1, and the heat-conducting panel 2, the burner 12, the bottom wall 9, and the annular side wall 8 are installed on the base shell assembly 1.

[0083] The burner 12 introduces gas and mixes it with air, and then burns it to convert chemical energy into heat energy for release. As a preferred burner 12, it at least includes a gas intake pipe, an air intake pipe, a mixing chamber, and a combustion surface layer. It is further preferred that the combustion surface layer has a metal or ceramic porous carrier. After the gas and air are mixed in the mixing chamber, they burn on the surface of the metal or ceramic porous carrier and release heat energy mainly in the form of infrared radiation.

[0084] Among them, the heat-conducting panel 2 is used to transfer the infrared heat energy released by the combustion of the burner 12. In a preferred embodiment, the heat-conducting panel 2 is a directional heat-conducting panel 2, so that the infrared rays are conducted and radiated in the direction of penetrating the heat-conducting panel 2 from the spacing to the outside, but are not conducted along the extension direction of the heat-conducting panel 2 itself. Therefore, when the gas cooker is in use, the area where the heat-conducting panel 2 is located above the burner 12 is the high-temperature area 4, and the temperature of other areas does not increase significantly. Compared with the prior art in which the entire panel is heated when the burner 12 burns under the metal panel, this embodiment has significant progress, the heat is concentrated above the combustion area, the thermal efficiency is higher, and unnecessary temperature rise in other areas of the panel is prevented, which can prevent scalding users and allow other areas of the panel to be used for other purposes. Preferably, the heat-conducting panel 2 includes a directional heat-conducting microcrystalline panel.

[0085] In another preferred embodiment, the top of the base shell assembly 1 is an upper shell or a top panel, and the upper shell or the top panel has an opening for embedding the heat-conducting panel 2. The upper shell or the top panel has a non-heat-conducting property, or the upper shell or the top panel has a heat-conducting property, but the upper shell or the top panel is separated from the heat-conducting panel 2 by a non-heat-conducting material.

[0086] In this embodiment, the blocking and diverting assembly is arranged within the spacing, and is used to block and divert the hot flue gas diffused to the blocking and diverting assembly. In one embodiment, in the area located at the periphery of the blocking and diverting assembly, the bottom wall 9 or the annular side wall 8 is provided with a smoke exhaust port 19. In another embodiment, in the area located at the periphery of the blocking and diverting assembly, the bottom wall 9 and the annular side wall 8 are respectively provided with a smoke exhaust port 19. In another embodiment, in the area located at the periphery of the blocking and diverting assembly, a smoke exhaust port 19 is provided at the connection portion 63 between the bottom wall 9 and the annular side wall 8, and a portion of the smoke exhaust port 19 is located at the bottom wall 9, and the other portion is located at the annular side wall 8.

[0087] In this embodiment, a smoke exhaust channel 22 is formed between the blocking and diverting assembly and the inner surface of the annular side wall 8, that is, there is a space between the blocking and diverting assembly and the inner surface of the annular side wall 8, and the space forms the smoke exhaust channel 22, which is used to guide the hot flue gas blocked and diverted by the blocking and diverting assembly to the smoke exhaust port 19.

[0088] Based on this design, the combustion area of ​​the gas cooker is located below the heat-conducting panel 2, and the pot is placed directly on the heat-conducting panel 2. The infrared heat energy generated by the combustion of the burner 12 transfers the heat energy to the pot through the heat-conducting panel 2 to achieve its heating. Compared with the prior art, the existing pot support exposed on the upper surface of the cooker can be eliminated, making the upper surface of the cooker neat and easy to clean, and having stronger wind resistance for low and micro fires. On the other hand, during the cooking process, the pot can be placed flat on the heat-conducting panel 2, overcoming the defect of the pot being placed on the elevated pot support in the prior art that is unstable. Since there is no need for a pot support, the space on the panel surface is no longer occupied. When the user does not use the burner 12 to heat the cooking dish, the panel surface space can be used by the user for other purposes, such as placing kitchen equipment or processing food in the panel area. Moreover, the upper surface of the cooker is neater and flatter, making the entire cooker and panel easier to clean.

[0089] At the same time, the burner 12, the bottom wall 9, and the annular side wall 8, since the burner 12 is located below the heat-conducting panel 2, compared with the open-air open combustion in the prior art, the combustion area is not affected by the wind in the air, etc., and the combustion is more stable, especially when the fire is small or micro.

[0090] Moreover, in the prior art, the waste gas generated by the combustion of the gas stove can only be directly discharged into the kitchen, and a part of the waste gas is sucked away together with the oil smoke through the range hood, but a large amount of waste gas still directly diffuses into the kitchen, and harmful substances such as carbon monoxide and nitrogen oxides in the waste gas will damage human health. In this embodiment, the waste gas generated by the combustion is discharged through the exhaust port 19 connected to the negative pressure exhaust pipe, which can be directly discharged into the kitchen, and can also be completely collected through the pipe and discharged to the outside of the kitchen. When the waste gas is discharged outdoors, it can avoid polluting the indoor environment and endangering human health.

[0091] In this embodiment, Figure 2 , Figure 3 and Figure 7 As shown, a fresh air exchange device is also included, and the fresh air exchange device is installed on the base shell component 1. Among them, the fresh air exchange device includes a fan 20, an exhaust duct 4, an oxygen supply duct 5 and smoke exhaust ducts 11, 21, one end of the smoke exhaust duct 11, 21 is connected to the smoke exhaust port 19, and the other end is connected to the exhaust duct 4, the air inlet of the oxygen supply duct 5 is connected to the outside of the base shell component 1, and the air outlet is connected to the inside of the base shell component 1, and is arranged between the fresh air exchange device and the oxygen supply duct 5 and the exhaust duct 4 (the oxygen supply duct 5 and the exhaust duct 4 are preferably integrated together to form an air inlet and outlet connector), which is used to generate a pressure difference inside the base shell component 1 when the fan 20 is started, so that fresh air can supplement combustion oxygen for the burner 12 through the oxygen supply duct 5, and on the other hand, a negative pressure is formed at the smoke exhaust port 19 to send the hot smoke generated by combustion to the exhaust duct 4 through the smoke exhaust ducts 11, 21 in sequence for discharge. Preferably, the fan 20 can use the method of independent air supply for air intake and exhaust to perform air convection circulation.

[0092] Since the present embodiment also has the aforementioned fresh air exchange device, it can promote the airflow circulation of the burner 12, so that the burner 12 can replenish sufficient nutrients and discharge exhaust gas in time during the combustion process, thereby enabling the burner 12 to burn more fully and improve the thermal efficiency of the combustion.

[0093] In this embodiment, the blocking and diverting assembly includes a blocking and diverting ring disposed between the burner 12 and the smoke exhaust port 19 .

[0094] Among them, the blocking and diverting ring is in the form of a complete ring or an incomplete ring with an open gap. The blocking and diverting ring is arranged around the burner 12 and has multiple gas diversion guide channels, so that the hot flue gas is blocked by the blocking and diverting ring to generate turbulence, and then enters the exhaust channel after being diverted by multiple gas diversion guide channels.

[0095] This embodiment also provides a specific blocking and diverting ring, which includes a fin-shaped blocking and diverting ring 6, and the fin-shaped blocking and diverting ring 6 includes a plurality of fins 61. The fins 61 are distributed along the annular direction, and the gaps between the fins 61 form gas diversion guide channels 62, so that when the hot flue gas collides with the fins, it is blocked by the fins 61 to generate turbulence, and enters the exhaust channel 22 after being diverted by the plurality of gas diversion guide channels 62.

[0096] Preferably, the surface of the fin 61 has protrusions and grooves.

[0097] Preferably, the fin 61 has a multi-section bending structure.

[0098] In this embodiment, the fin-shaped blocking and diverting ring 6 further includes one or more connecting parts 63 for connecting the fins 61. Preferably, the connecting part 63 includes an annular connecting part 63, which is a complete annular shape or an incomplete annular shape with an open gap, and each fin 61 is respectively connected to the annular connecting part 63. That is, for the annular connecting part 63, a plurality of fins 61 are arranged on the annular connecting part 63 along an annular interval, and finally form the fin-shaped blocking and diverting ring 6.

[0099] In this embodiment, the blocking and diverting ring is configured to have a heat-conducting property, and preferably, the fin 61 includes a heat-conducting fin. Preferably, the connecting portion 63 includes a heat-conducting connecting portion 63. When the fin 61 and the connecting portion 63 are made of a heat-conducting material, such as a metal structure, the fin-shaped blocking and diverting ring 6 absorbs the heat in the hot flue gas and heats up to form a heat radiator to radiate infrared heat energy, thereby increasing the infrared heat radiation intensity above the heat-conducting panel 2.

[0100] Preferably, the top of the blocking and diverting ring is butted against the heat-conducting panel 2. Since the blocking and diverting ring is in contact with the heat-conducting panel 2, direct heat conduction occurs between the blocking and diverting ring and the heat-conducting panel 2, thereby improving thermal efficiency.

[0101] In this embodiment, the blocking and diverting component is arranged within the spacing, which is used to block and divert the hot flue gas diffused to the blocking and diverting component.

Based on this design, when the high-temperature hot flue gas generated by the burner 12 flows from the combustion surface of the burner 12 to the smoke exhaust port 19, the blocking and diverting components have a blocking and diverting effect on the hot flue gas, so that the process of the hot flue gas flowing to the smoke exhaust port 19 is delayed and a turbulent effect is formed, so that the hot flue gas is in contact with the heat-conducting panel 2 and / or the blocking and diverting components for a longer period of time to fully release and transfer heat energy, and the hot flue gas and radiated infrared rays that form the turbulent effect are repeatedly refracted within the spacing and then radiate and transfer heat energy outward from the heat-conducting panel 2 in a direction, thereby significantly improving the infrared heat energy radiation effect above the heat-conducting panel 2 and significantly improving the thermal efficiency of the gas cooker.

[0102] Preferably, the bottom wall 9 is provided with a spring 17 for pressing the top of the blocking and diverting ring against the heat conducting panel 2. Thus, the top of the blocking and diverting ring is in close contact with the heat conducting panel 2, which can not only adapt to assembly errors, but also improve the heat conduction efficiency. Preferably, the fin-shaped blocking and diverting ring 6 has a spring mounting hole 64.

[0103] Preferably, a spring 17 is provided between the bottom of the bottom wall 9 and the base shell assembly 1 to press the top of the side wall against the heat conducting panel 2.

[0104] In this embodiment, a control system 15 is further included, which is used to control the start and stop and / or operating parameters of the burner 12 and the fan 20. Preferably, the control system 15 includes:

Since the user's identity can be verified by the face recognition system and / or the fingerprint recognition system, it can prevent children and others from operating the gas stove by mistake, thereby improving the safety of the gas stove.

[0110] Further preferably, it also includes an interconnected screen-shifting and split-screen display system.

[0111] Preferably, a sensor 13 is further included to detect whether there is a pot on the heat-conducting panel 2 and / or whether the pot on the heat-conducting panel 2 is in a dry-boiling state, and to feed back a detection signal to the control system 15.
