Description

Technical Field

[0001] This application relates to a kitchen appliance, and particularly to an energy - concentrating ring and a cooking stove applying the energy - concentrating ring.

Background Art

[0002] Cooking stoves are essential kitchen utensils in the vast majority of families. In order to increase the firepower, improve the efficiency and reduce the energy consumption, existing cooking stoves often add an energy - concentrating ring around the burner. By wrapping the energy - concentrating ring around the periphery of the cooking stove, the heat generated during gas combustion is concentrated, the flame becomes more concentrated, and thus the effects of high firepower, high efficiency and low energy consumption are achieved.

[0003] However, after adding an energy - concentrating ring outside the cooking stove, the outside cold air is isolated from the flame of the cooking stove, resulting in insufficient supply of secondary air required for flame combustion, and thus incomplete combustion of gas. Especially for a square energy - concentrating ring, more carbon monoxide is likely to accumulate at the corners, leading to an excessive concentration and endangering the life safety of users.

[0004] Unless there is sufficient evidence to support it, the prior art described here does not mean that these prior arts were known to those of ordinary skill in the art related to this application before the filing date of this application.

Summary of the Invention

[0005] An object of an embodiment of this application is to propose an improved energy - concentrating ring and cooking stove for at least one of the above - mentioned technical problems and / or other possible technical problems not mentioned in this application.

[0006] According to a first aspect of this application, an embodiment of this application provides an energy - concentrating ring for a burner of a cooking stove. The energy - concentrating ring includes a polygon - shaped heat - concentrating part that circumferentially surrounds the burner. The heat - concentrating part includes corner parts and side parts, and the corner parts are clamped between two adjacent side parts. A flow - guiding rib that protrudes upward is provided at a position of the side part close to the corner part, and the flow - guiding rib extends substantially in the vertical direction on the inner side wall of the heat - concentrating part.

[0007] Thus, the flue gas generated by combustion is blocked by the flow - guiding rib after reaching the side part, and will not gather towards the corner part along the circumference of the heat - concentrating part, effectively preventing the phenomenon of excessive carbon monoxide concentration that may occur at the corner part.

[0008] According to an optional embodiment of this application, the flow - guiding ribs on two adjacent side parts are symmetrically distributed.

[0009] According to an optional embodiment of this application, the cross - section of the flow - guiding rib perpendicular to its extending direction is semi - circular or trapezoidal, and gradually decreases from bottom to top. The width of the cross - section is 2 - 3 mm, and the height of the cross - section is 1.2 - 3 mm.

[0010] According to an alternative embodiment of the present application, the flow guiding ribs are linear; the virtual extension line of the flow guiding ribs intersects with the central axis of the burner.

[0011] According to an alternative embodiment of the present application, the flow guiding ribs are arc-shaped; the virtual extension lines of the chord lines at both ends of the flow guiding ribs intersect with the central axis of the burner.

[0012] According to an alternative embodiment of the present application, the included angle range between the virtual extension line and the plane where the burner is located is 20° - 45°.

[0013] According to an alternative embodiment of the present application, the energy concentrating ring further includes a horizontal annular surface connected to the bottom circumference of the heat concentrating part; the first end of the flow guiding rib extends to the joint of the heat concentrating part and the horizontal annular surface, and the second end extends to the top of the heat concentrating part.

[0014] According to an alternative embodiment of the present application, the distance range between adjacent first ends located on the same side part is 15 - 30 mm.

[0015] According to an alternative embodiment of the present application, the flow guiding ribs and the heat concentrating part are integrally formed.

[0016] According to the second aspect of the present application, an embodiment of the present application provides a cooking appliance, including the energy concentrating ring as described in any of the above embodiments.

[0017] It should be noted here that for the directional expressions in the present application, if not otherwise specified, they are based on the normal use state of the gas stove.

[0026] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by this application more clearly understood, this application will be further described in detail below with reference to the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit the scope of protection of this application.

[0027] like Figure 1 As shown, a heat-gathering ring 1 is used for a burner 2 of a stove. The heat-gathering ring 1 includes a polygonal heat-gathering portion 3 that circumferentially surrounds the burner 2. The heat-gathering portion 3 includes corners 31 and sides 32, with the corners 31 sandwiched between two adjacent sides 32. In the polygonal heat-gathering ring 1, smoke released from combustion is blocked when it reaches the sides 32 of the heat-gathering portion 3. This generates both an upward component of force to dissipate the smoke and a circumferential component of force to gather toward the corners 31. This often results in more smoke being gathered at the corners 31 than at the sides 32, which can easily lead to excessive carbon monoxide concentrations in certain areas, potentially endangering personal safety.

[0028] For this reason, Figures 1-3 As shown, the present application provides an upwardly protruding guide rib 4 at a position near the corner 31 of the edge 32. The guide rib 4 extends generally in the vertical direction on the inner sidewall of the heat collecting portion 3. The vertical direction in the present application refers to a direction perpendicular to the circumferential direction of the heat collecting portion 3. This can block the circumferential diffusion of the flue gas reaching the edge 32, thereby reducing the carbon monoxide concentration in the corner 31.

[0029] In addition, the corner 31 and the side 32 can be integrally formed or separately formed and then connected together. The guide rib 4 can be located at a position where the side 32 is close to the corner 31 or at a position where the corner 31 is close to the side 32, which is not limited here.

[0030] According to an exemplary embodiment of the present application, Figure 2 and 3 As shown, the guide ribs 4 on two adjacent sides 32 are symmetrically distributed. Specifically, the number and arrangement of the guide ribs 4 on two adjacent sides 32 are symmetrically distributed with the center line of the included angle 31 as the axis, which is conducive to the uniform release of smoke.

[0031] According to an exemplary embodiment of the present application, the cross-section of the flow guiding rib 4 perpendicular to its extending direction is semi-circular or trapezoidal, and gradually decreases from bottom to top, which can better guide the airflow. The airflow mixed with particles such as flue gas can be discharged from the energy gathering ring 1 more quickly along the channels formed between the flow guiding ribs 4. The width of this cross-section is 2-3 mm, and the height is 1.2-3 mm, which is beneficial to preventing the flue gas from diffusing circumferentially to the corner 31.

[0032] According to an exemplary embodiment of the present application, as Figure 2 shown, the flow guiding rib 4 is linear, which is beneficial to the smooth upward flow of the flue gas. During the combustion process, the flue gas is discharged from the burner 2. The virtual extension line L1 of the flow guiding rib 4 intersects with the central axis A-A of the burner 2, as Figure 1 shown, so that the extending direction of the flow guiding rib 4 is consistent with the discharging direction of the flue gas, which is beneficial to the flue gas being discharged along the flow guiding rib 4.

[0033] According to an exemplary embodiment of the present application, as Figure 3 shown, the flow guiding rib 4 is arc-shaped. The arc-shaped flow guiding rib 4 has a longer stroke than the linear one, and the high-temperature flue gas stays in the heat gathering part 3 for a longer time, which is beneficial to improving the thermal efficiency of the cooker. During the combustion process, the flue gas is discharged from the burner 2. The virtual extension lines of the chord lines at both ends of the flow guiding rib 4 intersect with the central axis A-A of the burner 2, as Figure 1 shown, so that the extending direction of the flow guiding rib 4 is consistent with the discharging direction of the flue gas, which is beneficial to the flue gas being discharged along the flow guiding rib 4.

[0034] Furthermore, the included angle range between the virtual extension line and the plane where the burner 2 is located is 20°-45°. The plane where the burner 2 is located is the horizontal plane in the normal use state of the cooker. Configuring the included angle between the virtual extension line and the horizontal plane to be close to the included angle between the adjacent burner holes and the horizontal plane is beneficial to the flue gas discharged from the burner holes being discharged along the flow guiding rib 4. The range of the above-mentioned included angle is between 20°-45°.

[0035] According to an exemplary embodiment of the present application, as Figure 2 and 3 shown, the energy gathering ring 1 further includes a horizontal annular surface part 5 connected to the bottom circumference of the heat gathering part 3. The horizontal annular surface part 5 is beneficial to preventing the flue gas from escaping from the bottom and improving the thermal efficiency of the cooker. The first end 41 of the flow guiding rib 4 extends to the joint of the heat gathering part 3 and the horizontal annular surface part 5, and the second end 42 extends to the top of the heat gathering part, which is beneficial to the flue gas gathered at the bottom being discharged along the extending direction of the flow guiding rib 4.

[0036] According to an exemplary embodiment of the present application, the distance range between adjacent first ends 41 located on the same side edge 32 is 15 - 30 mm. Generally, if the flow guiding ribs 4 are arranged densely, it will hinder the emission and flow of flue gas. If they are arranged sparsely, the effect of guiding the flue gas flow towards the corner 31 is not good. 15 - 30 mm is a more preferred interval.

[0037] According to an exemplary embodiment of the present application, the flow guiding ribs 4 and the heat collecting part 3 are integrally formed, which is beneficial to reducing the complexity of the structure.

[0038] The present application also proposes a stove embodiment, and the stove includes the above-mentioned energy gathering ring 1. While ensuring good thermal efficiency, the stove avoids excessive concentration of flue gas towards the corner 31, so that the carbon monoxide concentration does not exceed the standard.

[0039] Components of different embodiments can be combined with each other in any feasible way to achieve the purpose of the present application.

[0040] It should be additionally noted that the present application should not be understood as being limited to the above-described embodiments, but should be understood as covering all possible implementation cases determined by combining the claims of the present application with the disclosure in the specification. Therefore, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present application without departing from the technical solution of the present application shall fall within the protection scope of the technical solution of the present application.
