Technical Field
[0001] The utility model relates to the field of stoves, in particular to an energy-gathering pot bracket and a stove comprising the same. Background Art
[0002] As gas stoves become more common in home kitchens, competition in the gas stove market is becoming increasingly fierce. Consumers are focusing on features such as greater firepower, higher thermal efficiency, and easier cleaning.
[0003] However, under the premise of high load, good flame combustion state, enhanced combustion heat absorption, or reduced heat loss are all ways to improve the thermal efficiency of the stove.
[0004] When outside air enters the gas stove to provide oxygen for fuel combustion, the air temperature is usually room temperature, which is significantly different from the ignition temperature of the gas. Existing technologies cannot preheat the secondary air well, which can easily damage the gas stove. Utility Model Content
[0005] The technical problem to be solved by the present invention is to overcome the defect in the prior art that when external air enters the gas stove to provide oxygen for fuel combustion, the temperature of the air is usually room temperature, which is greatly different from the ignition temperature of the gas. The prior art cannot preheat the secondary air well, which easily damages the gas stove. Provided are an energy-gathering pot bracket and a stove containing the same.
[0006] The utility model solves the above technical problems through the following technical solutions:
[0007] An energy-gathering pot support is characterized in that it includes:
[0008] a main body portion, the main body portion being arranged around the burner and comprising an annular cavity;
[0009] a partition, the partition dividing the annular cavity into an inlet cavity and an outlet cavity that are interconnected, at least one end of the partition being connected to a cavity wall on one side of the annular cavity, and the other end of the partition extending toward the cavity wall on the other side of the annular cavity and being bent to form a curled guide surface of the inlet cavity;
[0010] The main body also includes an air inlet far away from the burner and an air outlet close to the burner, the air inlet is connected to the air inlet cavity, and the air outlet is connected to the air outlet cavity.
[0011] In this solution, the above-mentioned structure is adopted. When the stove burns, the flame heat radiates to the surrounding air and smoke, and heat conduction heats the main body of the pot support. Secondary air enters the burner from the outside of the pot support through the annular cavity of the main body. When passing through the annular cavity, the pot support can radiate heat to the secondary air to preheat the secondary air. The annular cavity is provided with a partition to form an air inlet chamber and an air outlet chamber. The air inlet chamber forms a curled guide surface by the curling of the partition. After entering the air inlet chamber, the secondary air forms a vortex under the action of the curled guide surface, forming a large air flow circulation on the air flow surface of the air inlet chamber, increasing the heating area and accelerating heat exchange. This makes the secondary air temperature higher when it reaches the burner, and the combustion effect is better. At the same time, the main body can also form a physical barrier between the flame and the outside air, reducing the rapid loss of smoke and reducing the heat loss caused by its discharge process.
[0012] Preferably, the partition includes an upper partition and a lower partition, and the upper partition and the lower partition divide the annular cavity longitudinally to form a first air inlet cavity located above, a second air inlet cavity located below, and an air outlet cavity located between the first air inlet cavity and the second air inlet cavity. The upper partition is curled upward, and the lower partition is curled downward. The air inlet includes a first air inlet and a second air inlet respectively connected to the first air inlet cavity and the second air inlet cavity.
[0013] In this solution, the above-mentioned structure is adopted, and the upper baffle and the lower baffle divide the internal area of the cavity into three layers: upper, middle and lower. The upper layer of the cavity is the upper inlet cavity, which is close to the flame and has a higher internal air flow temperature. The lower layer of the cavity is the lower air inlet cavity, and the internal air flow is also preheated. The temperature is relatively low, but higher than the external secondary air temperature. The upper baffle is curled upward, and the lower baffle is curled downward, so that relatively independent vortices are formed in the upper and lower layers of the cavity, and both meet and flow out in the middle air outlet cavity. The vortices in the upper and lower air inlet cavities rotate in opposite directions, and the two vortices meet at the outlet and flow in the same direction to form a coupled structure. This coupled arrangement structure of multi-partitioned vortices and high-frequency heat flow can enhance the airflow vortex disturbance, increase the secondary air contact area, and fully heat the cold air.
[0014] Preferably, the first air inlet is arranged above the upper baffle, and the second air inlet is arranged below the lower baffle; and / or
[0015] The air outlet is provided between the upper partition plate and the lower partition plate.
[0016] In this solution, the above structure is adopted, which can ensure that the incoming secondary air can be preheated before flowing out through the upper and lower air inlet cavities, ensuring sufficient preheating.
[0017] Preferably, there is a gap between one end of the partition and the cavity wall of the annular cavity, and the air inlet cavity and the air outlet cavity are connected through the gap.
[0018] In this solution, the above structure is adopted, and the air inlet cavity and the air outlet cavity are connected through the gap at the end of the partition, so that the curled guide surface of the partition can fully act on the secondary air entering the air inlet cavity, making it easier to form a vortex.
[0019] Preferably, the gap is arranged close to the air inlet.
[0020] In this solution, the above structure is adopted, and the gap is set close to the air inlet, which makes it easier for the air flow to circulate fully in the air inlet chamber and then flow out, thereby improving the heat exchange efficiency.
[0021] Preferably, a plurality of partitions are provided in the annular cavity, and the plurality of partitions are distributed in an annular shape in the annular cavity, with a gap between two adjacent partitions.
[0022] In this solution, the above structure is adopted, and different partitions correspond to different air intake chambers. The partitions facilitate the circulation of secondary air between different air intake chambers, thereby enhancing air circulation.
[0023] Preferably, the air inlet and / or the air outlet are not provided at the spaced position.
[0024] In this solution, the above structure is adopted to prevent the secondary air from passing directly through the annular cavity, thereby ensuring sufficient heating of the secondary air.
[0025] Preferably, the partition further comprises a low emissivity coating.
[0026] In this solution, the above structure is adopted so that the partition acts as a thermal insulation layer, thereby reducing heat loss during air flow.
[0027] Preferably, the air outlet height h and the circular height H of the burner's fire hole satisfy h+1.2≤H≤h+5.
[0028] In this solution, the above structure is adopted. When the preheated secondary air contacts the burner, it can be fully burned with the fuel gas, thereby improving combustion efficiency and reducing CO emissions.
[0029] A stove is characterized in that it comprises the above-mentioned energy-gathering pot support and a burner, wherein the main body of the energy-gathering pot support is arranged around the burner.
[0030] In this solution, the above-mentioned structure is adopted. When the stove burns, the flame heat radiates to the surrounding air and smoke, and heat conduction heats the main body of the pot support. Secondary air enters the burner from the outside of the pot support through the annular cavity of the main body. When passing through the annular cavity, the pot support can radiate heat to the secondary air to preheat the secondary air. The annular cavity is provided with a partition to form an air inlet chamber and an air outlet chamber. The air inlet chamber forms a curled guide surface by the curling of the partition. After entering the air inlet chamber, the secondary air forms a vortex under the action of the curled guide surface, forming a large air flow circulation on the air flow surface of the air inlet chamber, increasing the heating area and accelerating heat exchange. This makes the secondary air temperature higher when it reaches the burner, and the combustion effect is better. At the same time, the main body can also form a physical barrier between the flame and the outside air, reducing the rapid loss of smoke and reducing the heat loss caused by its discharge process.
[0031] The positive progressive effect of the present invention is that the present invention discloses an energy-gathering pot support and a stove including the same. When the stove burns, the flame heat radiates to the surrounding air and smoke, and the heat conduction heats the main body of the pot support. Secondary air enters the burner from the outside of the pot support through the annular cavity of the main body. When passing through the annular cavity, the pot support can radiate heat to the secondary air to preheat the secondary air. The annular cavity is provided with a partition to form an air inlet chamber and an air outlet chamber. The air inlet chamber forms a curled guide surface by the curling of the partition. After entering the air inlet chamber, the secondary air forms a vortex under the action of the curled guide surface, forming a large air flow circulation on the air flow surface of the air inlet chamber, increasing the heating area and accelerating heat exchange. The secondary air is made to have a higher temperature when it reaches the burner, and the combustion effect is better. At the same time, the main body can also form a physical barrier between the flame and the outside air, reducing the rapid loss of smoke and reducing the heat loss caused by its discharge process.

[0060] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.
[0061] Example 1
[0062] like Figure 1As shown, this embodiment provides a condenser support, which includes a main body 100 and a partition. The main body 100 is arranged around the burner and includes an annular cavity 110. The partition divides the annular cavity 110 into an air inlet cavity 111 and an air outlet cavity 112, which are interconnected. At least one end of the partition is connected to the cavity wall of the annular cavity 110, and the other end of the partition extends toward the cavity wall of the other side of the annular cavity 110 and bends to form a curled guide surface 1401 of the air inlet cavity 111. The main body 100 also includes an air inlet away from the burner and an air outlet 130 close to the burner. The air inlet is connected to the air inlet cavity 111, and the air outlet 130 is connected to the air outlet cavity 112.
[0063] The energy-gathering pot support of this embodiment further includes a corner piece 200 provided on the main body 100 for supporting and carrying the pot.
[0064] In this embodiment, the main body 100 is an annular structure, and the interior is hollow to form an annular cavity 110 (such as Figure 7 As shown), an air inlet and an air outlet 130 are respectively provided on both sides of the annular structure so as to conduct the air from the outside of the pot support through its annular cavity 110 to the burner inside the pot support and to supply the burner with secondary air. When the stove burns, the flame heat radiates to the surrounding air and smoke, and the heat conduction heats the main body 100 of the pot support. The secondary air enters the burner from the outside of the pot support through the annular cavity 110 of the main body 100. When passing through the annular cavity 110, the pot support can radiate heat to the secondary air to preheat the secondary air. The annular cavity 110 has a partition to form an air inlet cavity and an air outlet chamber. The air inlet cavity forms a curling guide surface 1401 by curling the partition. After entering the air inlet cavity, the secondary air forms a vortex under the action of the curling guide surface 1401, forming a large air flow circulation on the air flow surface of the air inlet cavity, as shown in FIG. Figure 6 The middle arrow indicates the flow of secondary air through the intake chamber, increasing the heated surface area and accelerating heat exchange. This results in a higher temperature for the secondary air upon reaching the burner, enhancing combustion efficiency. Furthermore, the main body 100 forms a physical barrier between the flame and the outside air, reducing the rapid escape of smoke and the resulting heat loss during exhaust.
[0065] like Figures 2 to 5 As shown, Figure 2: Figure 3 is a schematic diagram of the internal structure of the main body 100 without its cover. As can be seen in the figure, the partition of this embodiment is composed of an upper partition 141 and a lower partition 142. The upper partition 141 and the lower partition 142 divide the annular cavity 110 longitudinally into a first air inlet cavity 111 located at the top, a second air inlet cavity 111 located at the bottom, and an air outlet cavity 112 located between the first air inlet cavity 111 and the second air inlet cavity 111 (in this embodiment, the first air inlet cavity and the second air inlet cavity are both denoted by 111). The upper partition 141 is curled upward, and the lower partition 142 is curled downward. The air inlet includes a first air inlet 121 and a second air inlet 122 that are respectively connected to the first air inlet cavity 111 and the second air inlet cavity 111.
[0066] In this embodiment, the upper baffle 141 and the lower baffle 142 both extend along the circumference direction of the annular cavity 110, and the upper baffle 141 and the lower baffle 142 divide the internal area of the annular cavity 110 into three layers: upper, middle and lower. The upper layer of the cavity is the upper air inlet cavity. The upper air inlet cavity 111 is located above the main body 100, close to the flame, and the internal air flow temperature is relatively high. The lower layer of the cavity is the lower air inlet cavity 111, and the internal air flow is also preheated. The temperature is relatively low, but higher than the external secondary air temperature. The upper baffle 141 curls upward, and the lower baffle 142 curls downward, so that the upper and lower layers of the cavity form relatively independent vortices, and both meet and flow out in the middle air outlet cavity 112. As shown Figure 6 As shown, the vortexes in the upper air inlet cavity 111 and the lower air inlet cavity 111 rotate in opposite directions, and the two vortices meet at the outlet of the middle air outlet cavity 112 and flow in the same direction to form a gear-like coupling structure. This coupling arrangement structure of multi-partitioned vortexes and high-frequency heat flow can enhance the airflow vortex disturbance, increase the secondary air contact area, and fully heat the cold air. The upper partition 141 and the lower partition 142 of this embodiment are both assembled in the annular cavity 110 through a fixing groove 150 opened on the inner side of the main body 100. The upper partition 141 and the lower partition 142 respectively include an upper fixed bending portion 1411 and a lower fixed bending portion 1421. The upper fixed bending portion 1411 and the lower fixed bending portion 1421 are respectively bent in a direction perpendicular to the extension direction of the upper partition 141 and the lower partition 142. During assembly, the upper partition 141 and the lower partition 142 are inserted into the annular cavity 110 from the fixing groove 150, and the upper fixed bending portion 1411 and the lower fixed bending portion 1421 are respectively clamped on the fixing groove 150 and the inner side of the main body to complete the fixation.
[0067] In other embodiments, partitions at other positions may be used, or only one air inlet cavity 111 may be formed to form a vortex, and the preheating performance of the secondary air may be improved to a certain extent without using a coupling method.
[0068] like Figure 5 、 Figure 6As shown, the first air inlet 121 is arranged above the upper partition 141 , the second air inlet 122 is arranged below the lower partition 142 , and the air outlet 130 is arranged between the upper partition 141 and the lower partition 142 .
[0069] In this embodiment, this ensures that incoming secondary air is preheated by passing through the upper and lower intake cavities 111 before exiting, ensuring sufficient preheating. In other embodiments, the number and location of the air inlets can be adjusted based on the changes in the baffles, as long as the incoming air first enters the intake cavities 111 and properly acts on the curled guide surfaces 1401 to form vortex preheating. Furthermore, the intake cavities 111 are preferably located on the upper side of the main body 100, as this side receives the most heat radiation from the flame, resulting in better thermal energy utilization.
[0070] like Figure 5 、 Figure 6 As shown, there is a gap 170 between one end of the partition and the cavity wall of the annular cavity 110 , and the air inlet cavity 111 and the air outlet cavity 112 are connected through the gap 170 .
[0071] In this embodiment, the inlet chamber 111 and the outlet chamber 112 are connected through the gap 170 at the end of the partition, allowing the curved guide surface 1401 of the partition to fully act on the secondary air entering the inlet chamber 111, thereby facilitating the formation of vortex flow. In other embodiments, structures arranged in other locations and in different forms may be used to connect the two chambers, such as by providing vent holes in the partition.
[0072] like Figure 6 As shown, gap 170 is positioned near the air inlet. In this embodiment, gap 170 is positioned near the air inlet to facilitate sufficient circulation of air within the air inlet cavity before exiting, thereby improving heat exchange efficiency. In other embodiments, gap 170 can also be positioned away from the air inlet, but this may shorten the flow path of the secondary air, thereby reducing the preheating effect.
[0073] like Figure 2 、 Figure 3 and Figure 8 As shown, multiple baffles are disposed within the annular cavity 110. These baffles are arranged in a ring shape within the cavity 110, with a gap 160 between adjacent baffles. In this embodiment, different baffles correspond to different inlet cavities, facilitating the flow of secondary air between these cavities and enhancing air circulation. The air inlet and outlet 130 are not provided at the gap 160. In this embodiment, the secondary air is prevented from passing directly through the annular cavity 110, ensuring sufficient heating of the secondary air.
[0074] In this embodiment, the partition further includes a low-emissivity coating. By spraying the low-emissivity coating, the radiation reflectivity of the partition is reduced, so that the partition itself can also serve as a thermal insulation layer, thereby reducing heat loss during airflow.
[0075] In addition, in this embodiment, the height h of the air outlet 130 and the circular height H of the burner's fire hole satisfy h+1.2≤H≤h+5. When the preheated secondary air contacts the burner, it can fully burn with the gas, improving combustion efficiency and reducing CO emissions.
[0076] This embodiment also provides a stove, comprising the above-described energy-gathering pot support and a burner. The main body 100 of the energy-gathering pot support surrounds the burner. When the stove burns, the flame radiates heat to the surrounding air and smoke, and heat conduction heats the main body 100 of the pot support. Secondary air enters the burner from the outside of the pot support through an annular cavity 110 of the main body 100. As it passes through the annular cavity 110, the pot support radiates heat to the secondary air, preheating it. The annular cavity 110 contains a baffle forming an inlet chamber and an outlet chamber. The inlet chamber is formed by the curvature of the baffle to form a curved guide surface 1401. After entering the inlet chamber, the curvature of the guide surface 1401 creates a vortex, forming a large airflow loop on the airflow surface of the inlet chamber, increasing the heated area and accelerating heat exchange. This results in a higher temperature for the secondary air upon reaching the burner, resulting in better combustion. The main body 100 also forms a physical barrier between the flame and the outside air, reducing the rapid escape of smoke and the resulting heat loss during exhaust.
[0077] Example 2
[0078] like Figure 9 As shown, this embodiment is substantially the same as embodiment 1, with the difference being that the partition of this embodiment is arranged differently. In this embodiment, there is only one partition 140, which also has a curled guide surface 1401. The partition 140 separates the annular cavity 110 into an air inlet cavity 111 and an air outlet cavity 112 located on the left and right sides respectively, wherein an air inlet 120 is opened corresponding to the air inlet cavity, and the air inlet 120 is opposite to the curled guide surface 1401, so that a vortex of secondary air is formed in the air inlet cavity 111, and the preheating of the secondary air is achieved through circulating flow.
