Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cooking stoves, in particular to an energy-gathering pan rack and a gas stove. Background Art
[0002] A gas stove is a device that uses combustible gas to generate heat. Cooking is performed by placing pots and pans over the flames. During the combustion of combustible gas, a continuous supply of secondary air is required. The oxygen in this secondary air helps the gas burn.
[0003] To improve combustion efficiency, some existing gas stoves are equipped with a heat-concentrating plate. This plate concentrates heat, reducing radiation and convection heat loss. It also separates secondary air from the combustion flue gases, allowing the secondary air to more effectively fuel the combustion flame, ensuring more complete combustion and improving combustion efficiency.
[0004] The inner ring of the gas stove's energy-gathering disk is spaced from the outer wall of the burner base to form a radial annular channel. Secondary air required for external ring fire combustion is drawn directly into this annular channel from the bottom of the energy-gathering disk. This gas stove suffers from drawbacks such as a short secondary air flow path, which prevents the air from being fully preheated before combustion, reducing combustion efficiency and the energy-gathering heat capacity of the energy-gathering disk. Utility Model Content

[0034] This embodiment discloses a gas stove including an energy-gathering pan rack, which is used to heat the pot during cooking. Figures 1 to 6 As shown, the energy-gathering pan rack includes an upper pan 1, a lower pan 2 and a fan 3, wherein the upper pan 1 and the lower pan 2 are respectively ring-shaped, and the fan 3 is used to send external air into the set space.
[0035] The upper and lower discs 1 and 2 are fastened together to form a secondary air preheating channel. An outer baffle 21 and an inner baffle 22 are positioned radially inward within the secondary air preheating channel. These two baffles divide the interior of the secondary air preheating channel into three compartments: an intake space 23 is defined between the outer baffle 21 and the wall of the lower disc 2; a primary preheating space 24 is defined between the outer baffle 21 and the inner baffle 22; and a secondary preheating space 25 is defined between the inner baffle 22 and the wall of the lower disc 2. In other words, from the outer edge of the lower disc 2 toward the burner, the intake space 23 is located on the outside, the primary preheating space 24 is located in the middle, and the secondary preheating space 25 is located on the inside.
[0036] The air intake space 23 is connected to the primary preheating space 24 through the outer baffle holes 211 on the outer baffle 21, and the primary preheating space 24 is connected to the secondary preheating space 25 through the inner baffle holes 221 on the inner baffle 22. The fan 3 delivers secondary air into the outer air intake space 23. The secondary air enters the primary preheating space 24 through the outer baffle holes 211, where it is preheated by heat exchange with the bottom wall of the upper tray 1 and the inner cavity of the lower tray 2. The secondary air then enters the secondary preheating space 25 through the inner baffle holes 221, where it also undergoes heat exchange with the bottom wall of the upper tray 1 and the inner cavity of the lower tray 2, achieving further deep preheating.
[0037] A secondary air supply hole 26 is provided on the wall surface near the center of the lower disk 2 (i.e., the wall surface near the burner). The preheated secondary air flows out from the secondary preheating space 25 through the secondary air supply hole 26 and reaches the burner, providing the air required for combustion.
[0038] The upper plate 1 of the energy-gathering plate pot stand can effectively insulate and preserve heat, thereby achieving an enhanced energy-gathering effect; the inner cavity of the lower plate 2 is provided with three spaces, and secondary air can circulate in the primary preheating space 24 and the secondary preheating space 25, extending the preheating path of the secondary air, so that the secondary air is fully preheated, which is beneficial to improving the combustion thermal efficiency.
[0039] The upper plate 1 and the lower plate 2 can be fixedly connected after being buckled together, so that the upper plate 1 and the lower plate 2 form an integral structure. After the secondary air enters, the upper plate 1 and the lower plate 2 will not be separated, which is safer to use. The upper plate 1 and the lower plate 2 can also be detachably connected after being buckled together, which is convenient for cleaning and replacement of parts, and the disassembly and assembly efficiency is high.
[0040] like Figure 2 As shown, the fan 3 includes a fan body 31 and a fixing portion 32 connected to each other, and the fixing portion 32 is used to fix the fan body 31 to the mounting base. The specific structure of the mounting base is not limited and can be located at any suitable position in the gas stove.
[0041] The fan body 31 is provided with a fan air inlet 311 and a fan air outlet 312 which are connected to each other. The fan air outlet 312 is connected to the air inlet space 23. Figures 1 to 4 As shown, the fan suction port 311 is located outside the lower plate 2, and the fan suction port 311 is located near the energy-gathering plate pot rack. The hot air around the energy-gathering plate pot rack is sucked into the fan suction port 311, and the hot air enters the air intake space 23 through the fan outlet 312, forming secondary air with a certain temperature, and the combustion thermal efficiency is high.
[0042] In order to avoid the secondary air from hitting the baffle head-on and causing loud noise during high-speed flow, such as Figures 1 to 6 As shown, the outer baffle 21 of the energy-concentrating pan support forms a predetermined angle with the extension direction of the fan outlet 312, and / or the inner baffle 22 forms a predetermined angle with the extension direction of the fan outlet 312. The specific inclination values of the outer baffle 21 and / or the inner baffle 22 are not limited and can be determined by multiple noise measurements to reduce noise without increasing the processing difficulty.
[0043] Based on the above structure, the extension direction of the fan intake 311 forms a predetermined angle with the extension direction of the fan outlet 312. In this embodiment, the fan intake 311 extends vertically upward, while the fan outlet 312 extends horizontally and along the radial direction of the lower tray 2. After entering the fan intake 311, the secondary air must bend at least once before reaching the fan outlet 312, effectively reducing wind speed and noise.
[0044] To reduce the flow velocity of the high-temperature flue gas, a flow-blocking protrusion 11 is formed on the upper disc 1 at a location corresponding to the secondary preheating space 25. This protrusion 11 projects away from the secondary preheating space 25. This protrusion 11 forms an annular ridge within the energy-concentrating disc support. The high-temperature flue gas generated by the burner forms a trapped vortex around this protrusion 11, increasing the thermal resistance to outward diffusion of the high-temperature flue gas and enabling more effective energy concentration.
[0045] In order to extend the preheating time of the secondary air, the volume of the primary preheating space 24 is larger than the volume of the air intake space 23. The secondary air stays in the primary preheating space 24 for a longer time and the heat exchange is more sufficient.
[0046] To reduce heat loss, in this embodiment, an upper cavity 12 is formed on the outer edge of the upper pan 1. This cavity 12 is located above and independent of the air intake space 23. Specifically, the upper cavity 12 is a closed structure filled with air or a material with low heat conductivity, thereby enhancing the pot rack's thermal insulation. The specific shape of the upper cavity 12 is not limited, as long as it concentrates and directs heat energy to the bottom of the pot, improving thermal energy utilization and accelerating food heating within the pot.
[0047] On the basis of the above structure, the energy-gathering pan rack also includes an auxiliary pan rack 4. The auxiliary pan rack 4 is located above the upper pan 1, which can not only prevent the high-temperature smoke from rising and escaping, but also provide stable support for the pot, making it more convenient to use.
[0048] The specific number of fans 3 provided in each energy-concentrating pan support is not limited; it serves to minimize costs while providing sufficient secondary air. Therefore, each energy-concentrating pan support can be equipped with only one fan 3, minimizing costs. In this embodiment, the energy-concentrating pan support includes at least two fans 3, all of which are symmetrically distributed relative to the center of the lower pan 2. This allows the high-temperature air surrounding the energy-concentrating pan support to be evenly drawn into the intake space 23, providing a sufficient supply of secondary air. This prevents high noise levels and vibrations caused by uneven air intake, resulting in a better user experience.
[0049] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
