Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and more specifically, to an adjustable energy-concentrating pot rack assembly. Background Technology

[0002] In gas stoves, the supply of secondary air is crucial for combustion efficiency, pollutant emissions, and flame stability. Existing technologies include solutions that use motor-driven air conditioning baffles to adjust the size of the secondary air inlet, addressing the fundamental issue of on-demand air supply adjustment. However, simply adjusting the opening size leaves room for optimization: the airflow direction from a regular opening is random, and some airflow may not be effectively directed to the burner nozzle root for combustion. Especially at small openings, poor airflow organization can lead to unnecessary interference with the flame, thus limiting further improvements in combustion performance. Utility Model Content

[0003] The purpose of this invention includes, for example, providing an adjustable energy-concentrating pot frame assembly that can not only precisely control the secondary airflow, but also actively guide the airflow direction to make it participate in combustion more efficiently and stably.

[0004] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides an adjustable energy-concentrating pot frame assembly, comprising: The pot rack body and the air conditioning vents provided on the pot rack body; The pot rack body is also provided with an air conditioning baffle corresponding to the air conditioning port. The air conditioning baffle moves relative to the air conditioning port to adjust the opening degree of the corresponding air conditioning port. Each of the air conditioning baffles is provided with a guide vane, which is configured to guide air through the air conditioning port and flow towards the lower part of the pot frame body.

[0005] The adjustable energy-concentrating boiler frame assembly in this solution allows for precise adjustment of the secondary air supply based on different heat loads by adjusting the position of the air conditioning baffle. Simultaneously, the coordinated adjustment of the air conditioning baffle position and the guiding effect of the guide vanes optimize the flow direction of the secondary air entering the gas collection chamber, ensuring it is directed and smoothly supplied to the required area of ​​the burner, avoiding airflow turbulence, and further improving combustion efficiency and flame stability.

[0006] In an optional embodiment, each of the air conditioning baffles is provided with a plurality of air guide vanes on the side near the pot frame body; the air guide vanes are directly opposite the center of the pot frame body.

[0007] In an optional embodiment, a plurality of the air deflectors are arranged in parallel on the air conditioning baffle.

[0008] In an optional embodiment, the height of the guide vane farther from the center of the pot frame body along the radial direction of the pot frame body is greater than the height of the guide vane closer to the center of the pot frame body.

[0009] In an optional embodiment, the height of the guide vanes on each of the air conditioning baffles increases sequentially from the radially inner side of the pot frame body to the radially outer side of the pot frame body.

[0010] In an optional embodiment, each of the guide vanes is tilted at an angle α toward the center of the pot frame body on the plate surface of the guide vane.

[0011] In an optional embodiment, the angle α of the guide vane is 30-60°.

[0012] In an optional embodiment, at least one actuation unit is further included. The number of actuation units, air conditioning baffles, and air conditioning vents are the same and they correspond one-to-one. The actuation unit is connected to the corresponding air conditioning baffle to drive the air conditioning baffle to move relative to the air conditioning vent, thereby adjusting the opening degree of the corresponding air conditioning vent.

[0013] In an optional embodiment, a connecting seat is provided on the bottom surface of the air conditioning baffle, and the actuating unit is connected to the connecting seat; a plurality of the guide vanes are provided on both sides of the connecting seat.

[0014] In an optional embodiment, adjacent air deflectors are located on the same straight line along the length of the air conditioning baffle.

[0015] The beneficial effects of this utility model embodiment include, for example: The adjustable energy-concentrating boiler frame assembly of this solution includes a boiler frame body and at least one air conditioning baffle. The air conditioning baffle moves relative to the air conditioning inlet, thereby adjusting the opening of the corresponding air conditioning inlet to precisely regulate the secondary air supply according to different heat loads. Each air conditioning baffle is equipped with a guide vane, which guides the secondary air flow towards the lower center of the boiler frame body, directing the secondary air to the lower center of the burner or the root area of ​​the burner orifice. This optimizes the flow direction of the secondary air entering the gas collection chamber, ensuring it is directed and smoothly supplied to the required area of ​​the burner, avoiding airflow turbulence, and further improving combustion efficiency and flame stability.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] Please refer to Figure 1 This embodiment provides an adjustable energy-concentrating pot frame assembly, including: The pot rack body 100 and the air conditioning port 101 provided on the pot rack body 100; The pot rack body 100 is also provided with an air conditioning baffle 200 corresponding to the air conditioning port 101. The air conditioning baffle 200 moves relative to the air conditioning port 101 to adjust the opening degree of the corresponding air conditioning port 101. Each of the air conditioning baffles 200 is provided with a guide vane 210, which is configured to guide air through the air conditioning port 101 and flow to the lower part of the pot rack body 100.

[0026] In this solution, the air conditioning baffle 200 of the adjustable energy-concentrating boiler frame assembly moves relative to the air conditioning port 101, thereby adjusting the opening degree of the corresponding air conditioning port 101 to precisely adjust the secondary air supply according to different heat loads. Each air conditioning baffle 200 is equipped with a guide vane 210; the guide vane 210 guides the secondary air flow to the lower center of the boiler frame body 100, that is, directs the secondary air to the lower center of the burner or the root area of ​​the flame holes, thereby optimizing the flow direction of the secondary air entering the gas collection chamber, so that it can be directionally and smoothly supplied to the required area of ​​the burner, avoiding airflow turbulence, and further improving combustion efficiency and flame stability.

[0027] Please see Figure 1 , Figure 2 , Figure 3 To learn more about the structural details of the adjustable energy-concentrating pot frame assembly.

[0028] As shown in the figure, the pot holder body 100 is horizontally placed on the gas stove panel, and its interior is hollow, forming a gas collecting chamber. At least one air conditioning port 101 is provided on the side wall or top surface of the pot holder body 100 to introduce external secondary air into the gas collecting chamber. Optionally, the number of air conditioning ports 101 is three, evenly distributed circumferentially. Furthermore, the pot holder body 100 is a hollow disc, and its upper surface is a concave arc surface. The shape of the air conditioning baffle 200 is adapted to the air conditioning port 101, and the air conditioning baffle 200 can completely cover the air conditioning port 101.

[0029] In an optional embodiment, each of the air conditioning baffles 200 is provided with a plurality of guide vanes 210 on the side near the pot frame body 100; the guide vanes 210 are directly opposite the center of the pot frame body 100. This causes the guide vanes 210 to guide the secondary air toward the gas collecting chamber, thereby directing the secondary air to the area below the center of the burner or at the root of the burner holes, thus improving combustion efficiency.

[0030] As can also be seen from the figure, in an optional embodiment, multiple guide vanes 210 are arranged in parallel on the air conditioning baffle 200. Because the guide vanes 210 are directly facing the center of the boiler body 100, they thus hinder the movement of secondary air along the radial direction of the boiler body 100. Instead, they guide the secondary air toward the air conditioning port 101 and downward to the area below the center of the boiler body 100 (that is, guide the secondary air to the area below the center of the burner or the root area of ​​the burner hole).

[0031] Furthermore, in an optional embodiment, the height of the guide vane 210 further away from the center of the pot frame body 100 is greater than the height of the guide vane 210 closer to the center of the pot frame body 100 in the radial direction. Because the burner is located at the center of the pot frame body 100, and more secondary airflow escapes from the center, increasing the height of the guide vane 210 further away from the center helps guide more secondary airflow towards the area below the center of the burner or the root region of the burner holes.

[0032] In an optional embodiment, the height of the guide vanes 210 on each air conditioning baffle 200 increases sequentially from the radially inner side to the radially outer side of the pot frame body 100. This makes the secondary airflow on the air conditioning baffle 200 more uniform and smoother.

[0033] In an optional embodiment, each guide vane 210 is inclined at an angle α toward the center of the boiler body 100 on the plate surface of the guide vane 210. In this way, the inclined guide vanes 210 can guide secondary air toward the area below the center of the burner or the root region of the burner holes.

[0034] In an optional embodiment, the tilt angle α of the guide vane 210 is 30-60°.

[0035] In an optional embodiment, at least one actuation unit 300 is further included. The number of actuation units 300, air conditioning baffles 200, and air conditioning vents 101 are the same and correspond one-to-one. The actuation unit 300 is connected to the corresponding air conditioning baffle 200 to drive the air conditioning baffle 200 to move relative to the air conditioning vent 101, thereby adjusting the opening degree of the corresponding air conditioning vent 101. The actuation unit 300 enables precise movement of the air conditioning baffle 200, thereby ensuring that the air conditioning vent 101 can reach a preset opening degree.

[0036] It should be noted that the air conditioning baffle 200 and the corresponding actuation unit 300 can be matched as a complete adjustment mechanism. It is easy to understand that in other embodiments of this utility model, the relative position of the air conditioning baffle 200 and the air conditioning port 101 can be adjusted directly by manual displacement, thereby adjusting the opening of the air conditioning port 101. This is just an example and is not intended to limit the scope.

[0037] Optionally, the actuation unit 300 includes a motor 310, a rotating screw shaft 320, and a connecting shaft 330. The motor 310 is rotatably connected to the rotating screw shaft 320 to drive the rotating screw shaft 320 to rotate. The outer end of the connecting shaft 330 is provided with an internal thread, and the rotating screw shaft 320 has an external thread. The connecting shaft 330 and the rotating screw shaft 320 form a lead screw and nut pair. The motor 310 is a rotary motor 310, which is fixedly mounted on the motor 310 mounting base 340, and its output shaft is connected to the rotating screw shaft 320.

[0038] Furthermore, such as Figure 2 and Figure 3 As shown, in an optional embodiment, a connecting seat 220 is provided on the bottom surface of the air conditioning baffle 200, and the actuation unit 300 is connected to the connecting seat 220; multiple guide vanes 210 are disposed on both sides of the connecting seat 220. This ensures that the guide vanes 210 at both ends of the connecting seat 220 are evenly arranged, thereby ensuring the guiding and diversion effect of the guide vanes 210 on the secondary air.

[0039] Optionally, the connecting seat 220 and the connecting shaft 330 are connected by a pin 400, so that the air conditioning baffle 200 can rotate toward the center of the pot frame body 100. A plurality of guide vanes 210 are symmetrically arranged on both sides of the connecting seat 220.

[0040] As shown in the figure, in an optional embodiment, adjacent air deflectors 210 are located on the same straight line along the length of the air conditioning baffle 200. This allows each air deflector 210 to be aligned with the length of the air conditioning baffle 200, thereby achieving a better airflow guiding effect.

[0041] In use, multiple parallel air guide vanes 210 are welded (or integrally stamped) onto the windward surface of the air conditioning baffle 200. These vanes 210 are inclined upward relative to the surface of the air conditioning baffle 200, with the outermost vane 210 being the highest, the middle vane 210 being the next highest, and the innermost vane 210 being the lowest. This height difference design is to compensate for the difference in airflow resistance caused by different positions, ensuring that the airflow entering from the entire opening area receives approximately the same guiding effect. The connecting shaft 330 and the rotating screw shaft 320 are threaded together. After the drive motor 310 starts, it drives the rotating screw shaft 320 to rotate, driving the connecting shaft 330 to move left and right, thereby controlling the opening and closing angle of the air conditioning baffle 200.

[0042] Working principle: When the motor 310 receives a high-load signal, it rotates forward at a certain angle, pushing the connecting shaft 330 inward and opening the air conditioning baffle 200. External secondary air enters through the air conditioning port 101. At this time, the air impacts the air guide vane 210. Due to the inclined surface of the guide vane 210, the airflow, which might otherwise be scattered, is gathered and directed in a specific direction—that is, along the direction indicated by the inclination angle of the guide vane 210—towards the root region of the burner's flame holes. This guided airflow can be more effectively drawn in by the burner's ejector action and mixed with the combustion gas, thereby achieving efficient and stable combustion.

[0043] Conversely, when the load decreases, the motor 310 reverses, pulling the air conditioning damper 200 to close the opening. Even with a small opening, the limited air entering can still be effectively organized by the guide vane 210, forming a concentrated and directional airflow. This effectively avoids the problem of the airflow being too weak to reach the combustion zone due to dispersion, ensuring combustion quality under low load.

[0044] In summary, this utility model provides an adjustable energy-concentrating pot frame assembly, which has at least the following advantages: (1) Dual optimization of flow rate and flow direction: The advantage of precisely controlling the secondary air flow rate by driving the air conditioning baffle 200 through the motor 310 is that the opening of the air conditioning baffle 200 and the air conditioning port 101 is automatically adjusted according to the different heat load levels (high, medium and low) when the burner is working, so as to ensure that the burner can be provided with an appropriate amount of secondary air under different working conditions; at the same time, through the innovative design of the guide vane 210, the airflow direction is actively guided, realizing the dual control of the "quality" and "quantity" of the secondary air supply.

[0045] (2) The combustion efficiency is greatly improved: the air flow organized by the guide vane 210 can be more concentrated and more accurately delivered to the area of ​​the burner that needs secondary air the most (such as the root of the burner hole), so that the gas and air are mixed more fully and the combustion is more complete, thereby significantly improving the thermal efficiency.

[0046] (3) Enhanced flame stability and reduced pollutant emissions: Directed and stable airflow replenishment avoids the impact of disordered airflow on the flame, enabling the burner to achieve a better combustion state under different heat loads. Especially at low loads and small openings, it can effectively prevent flame flickering and flameout. More complete combustion also significantly reduces the generation of incomplete combustion products such as carbon monoxide (CO) from the source, making it more environmentally friendly and healthier.

[0047] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
