Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to an energy-gathering pan rack and a gas stove. Background Art

[0002] Gas stoves generate heat by burning combustible gases, which is then used for cooking. To improve the utilization of this heat, some existing gas stoves are equipped with a pot rack with an energy-gathering plate. The plate's insulation and diversion structure improve the utilization of the high-temperature flue gas heat.

[0003] Existing gas stoves typically include a water tray and a cooking surface, with the energy-concentrating pan and pot holder mounted on top of the tray or panel. As the hot flue gas is insulated and directed, the energy-concentrating pan absorbs a significant amount of heat, causing it to heat up. This heat is then transferred to the water tray or panel through contacting components, causing it to overheat and even causing the glass panel to crack.

[0004] Moreover, the energy-gathering plate structure reduces the heat dissipation space under the pot rack, making the glass panel area near the water tray more likely to heat up too quickly; the setting of the energy-gathering plate reduces the space for replenishing secondary air under the pot rack, which limits the improvement of the thermal efficiency of the stove. Utility Model Content

[0005] The purpose of the utility model is to provide an energy-gathering plate pot rack and a gas stove, which solves the problem that the heat on the energy-gathering plate is transferred to the water receiving tray or the glass panel, causing the water receiving tray or the glass panel to break, and the gas stove has high thermal efficiency.

[0009] In one preferred embodiment, each group of the lower corner piece components includes a first lower corner piece and a second lower corner piece that are spaced apart, and one of the first lower corner piece and the second lower corner piece is higher than the other.

[0011] In one preferred embodiment, when at least one of the two lower corner pieces is arc-shaped, the curvature of the end away from the center of the energy concentrating disk body is greater than the curvature of the end close to the center of the energy concentrating disk body.

[0013] In one preferred embodiment, the windward end of the lower corner piece is an arc-shaped surface.

[0014] In one preferred embodiment, the energy concentrating disk body comprises an upper disk and a lower disk, and the upper disk and the lower disk are buckled together to form a heat-insulating cavity.

[0015] In one of the preferred embodiments, the upper disk is convex outward toward the direction away from the insulation cavity to form a guide ridge, the guide ridge is located on the side of the upper disk close to the center, and a guide groove is formed between the guide ridge and the outer edge of the upper disk.

Moreover, when the secondary air passes through the secondary air replenishment channel, the secondary air can exchange heat with the lower corner piece assembly, and a portion of the heat on the energy-gathering plate body and its surroundings is used to heat the secondary air, thereby preheating the secondary air while reducing heat transfer to the water receiving tray or glass panel, resulting in more complete combustion and high thermal efficiency of the gas stove.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0032] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0035] This embodiment discloses an energy-gathering pan rack and a gas stove including the energy-gathering pan rack, which are used to provide heat for cooking. Figures 1 to 7As shown, the energy-gathering pan support comprises an annular pan body 1, at least one set of lower corner piece assemblies 2, an auxiliary pan support 3, and upper corner pieces 4. The pan body 1 primarily serves to insulate and guide airflow, improving the utilization of high-temperature flue gas. The lower corner piece assemblies 2, located at the bottom of the pan body 1, provide support for placing the pan body 1 on a drain pan or panel. The upper corner pieces 4 support the bottom of the pan, and the auxiliary pan support 3 connects the upper corner pieces together.

[0036] Each set of lower corner panel assemblies 2 includes at least two spaced-apart lower corner panels, with a secondary air replenishment channel 23 formed between the two lower corner panels to guide and increase the amount of replenished secondary air, thereby improving the thermal efficiency of the stove. The contact area between the lower corner panel assembly 2 and the water tray or glass panel below is relatively small, reducing the amount of heat from the energy collecting plate body 1 and its surroundings that is transferred to the water tray or glass panel through the lower corner panel assembly 2, thereby reducing the risk of thermal shattering of the glass panel. Furthermore, when the secondary air passes through the secondary air replenishment channel 23, it can exchange heat with the lower corner panel assembly 2. A portion of the heat from the energy collecting plate body 1 and its surroundings is used to heat the secondary air, thereby preheating the secondary air while reducing heat transfer to the water tray or glass panel. This results in more complete combustion and higher thermal efficiency for the gas stove.

[0037] like Figures 2 to 5 As shown, the secondary air replenishment channel 23 extends radially along the energy collecting disk body 1, with the end close to the center of the energy collecting disk body 1 being the secondary air outlet end 231, and the end away from the center of the energy collecting disk body 1 being the secondary air inlet end 232. The width of the secondary air inlet end 232 is greater than the width of the secondary air outlet end 231, which helps to increase the speed of the secondary air when it is ejected from the secondary air outlet end 231, and the secondary air replenishment is more sufficient and efficient.

[0038] In order to avoid causing loud noise when the secondary air passes through the secondary air replenishment channel 23, the width of the secondary air replenishment channel 23 gradually decreases along the radial direction of the energy gathering disk body 1 toward the center of the energy gathering disk pot frame, and the flow rate of the secondary air will gradually increase, avoiding sudden changes in the flow rate of the secondary air due to sudden changes in the width of the secondary air replenishment channel 23, which can effectively reduce noise.

[0039] The specific structure of the lower corner panel assembly 2 is not limited, as long as the secondary air supply channel 23 is formed between the two lower corner panels. In this embodiment, each set of lower corner panel assemblies 2 includes a first lower corner panel 21 and a second lower corner panel 22 spaced apart from each other, with one of the first lower corner panel 21 and the second lower corner panel 22 being higher than the other.

[0040] The two lower corner pieces are designed to be one high and one low. After installation, the high lower corner piece abuts against the water receiving tray or glass panel below, and the low lower corner piece is suspended in the air, which can reduce the contact area between the lower corner piece assembly 2 and the water receiving tray or glass panel, reduce heat transfer, and reduce the probability of thermal breakage of the glass panel.

[0041] The specific structure for achieving "the width of the secondary air inlet end 232 being greater than the width of the secondary air outlet end 231" is not limited. In this embodiment, at least one of the lower corner panel assemblies 2 is curved or bendable, resulting in a simple and reasonable structure, easy processing, and low airflow noise. Specifically, when at least one of the two lower corner panels is curved, the curvature of the end farther from the center of the energy concentrating disk body 1 is greater than the curvature of the end closer to the center of the energy concentrating disk body 1, resulting in a more significant airflow acceleration effect and a more sufficient secondary air supply.

[0042] To prevent excessive wind resistance when the secondary air enters the secondary air replenishment channel 23, in this embodiment, the windward end of the lower corner piece is curved. When the secondary air reaches the secondary air inlet 232, it strikes the windward end of the lower corner piece. This curved surface helps guide the secondary air smoothly into the secondary air replenishment channel 23, minimizing wind resistance and noise.

[0043] Building on the above structure, a limiting recess 11 is provided at the bottom of the energy concentrating disc body 1, and the lower corner piece assembly 2 is positioned within this recess. This provides for a more secure installation of the lower corner piece assembly 2. Without changing the distance between the energy concentrating disc body 1 and the bottom mounting surface, the provision of the limiting recess 11 increases the height of the secondary air replenishment channel 23, allowing more secondary air to come into contact with the lower corner piece assembly 2. This reduces heat transfer to the water tray or glass panel, thereby extending the service life of the water tray or glass panel.

[0044] like Figure 6 and Figure 7 As shown, the energy concentrating disk body 1 includes an upper disk 12 and a lower disk 13, with the lower corner piece assembly 2 disposed on the outside of the bottom surface of the lower disk 13. The upper and lower disks 12, 13, when fastened together, enclose a heat-insulating cavity 14, which provides insulation and prevents excessive heat loss from the energy concentrating disk.

[0045] Building on the above structure, the upper disc 12 has an annular guide rib 121 that protrudes outward, away from the insulation cavity 14. This rib 121 is located near the center of the upper disc 12, and a guide groove 122 is formed between the rib 121 and the outer edge of the upper disc 12. Together, these ribs 121 and groove 122 form a guide structure that helps extend the residence time of high-temperature flue gas within the groove, enhancing heat exchange.

[0046] 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.
