Description

Technical Field

[0001] The utility model relates to the field of stoves, in particular to an energy-gathering ring and a pot support. Background Art

[0002] Gas stoves are essential cooking appliances in daily kitchen life. How to buy a gas stove with high thermal efficiency is a factor that users pay more attention to.

[0003] In order to improve the thermal efficiency of gas stoves, some energy-gathering rings have been used in China in recent years to improve the thermal efficiency of gas stoves. However, the smoke residence time of existing energy-gathering rings is short, and the high-temperature smoke cannot be fully burned. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the defects in the above-mentioned prior art and provide an energy-gathering ring and a pot support.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] An energy-gathering ring, comprising a body and a spoiler strip;

[0007] The body is an annular structure, and is used to be sleeved on the outer peripheral side of the fire cover of the burner;

[0008] The spoiler strip is arranged on the upper end surface of the main body and protrudes upward from the upper end surface of the main body. The spoiler strip is long and the length direction of the spoiler strip intersects with the first direction on the horizontal plane. The first direction is the direction of the energy focusing ring passing through the spoiler strip in the radial direction.

[0009] In this solution, the spoiler strip can change the flow direction of the flue gas, increase the disturbance of the airflow, and increase the time that the flue gas hovers above the main body of the energy-gathering ring, so that the flue gas can have more time to burn, ensuring that the flue gas can be fully burned and reducing carbon monoxide emissions.

[0010] Preferably, both ends of the spoiler strip in the length direction are arc ends.

[0011] In this solution, the above arrangement facilitates the flow of smoke.

[0012] Preferably, the spoiler strip is an arc-shaped structure, and along the first direction, the spoiler strip bends in a direction away from the center of the energy focusing ring.

[0013] In this solution, the above-mentioned setting can further increase the residence time of the flue gas, so that the flue gas can have more time to burn, ensuring that the flue gas can be fully burned and reducing carbon monoxide emissions.

[0014] Preferably, the inner circumference of the body is circular, and the outer circumference of the body is square.

[0015] In this solution, compared to the energy-gathering ring with a circular structure on the outer periphery, the length of the four corners of the square structure is greater than the radius of the circle when the diameter is equal, that is, the diagonal length of the square is greater than the radius of the circle. The smoke generated by the fire cover has a longer flow path in the diagonal direction of the square, which increases the convection time with the bottom of the pot, ensures that the smoke can fully burn, and reduces carbon monoxide emissions. The shape of the inner periphery is a circle that matches the shape of the fire cover, which can enhance the extensibility of the flame and is conducive to combustion. At the same time, the inner periphery of the circle can surround the entire burner, giving the smoke a relatively semi-sealed environment and gathering the smoke. When the flame radiates heat outward, the smoke is accompanied by secondary air and has a stronger ability to combine with the burning flame, thereby improving the thermal efficiency of the stove.

[0016] Preferably, the spoiler strips are arranged at four corners of the body.

[0017] In this solution, the four corners of the main body can provide a larger installation space for the spoiler strip, which facilitates the arrangement and installation of the spoiler strip.

[0018] Preferably, a plurality of the spoiler strips are provided at any one of the corners of the body, and a gas flow channel is formed between the plurality of the spoiler strips at the same corner.

[0019] In this solution, multiple spoiler strips are provided to increase the disturbance capacity of the flue gas and increase the time the flue gas hovers above the main body of the energy-gathering ring, so that the flue gas has more time to burn, ensuring that the flue gas can burn fully and reducing carbon monoxide emissions.

[0020] Preferably, for the plurality of spoiler strips located at the same corner, the plurality of spoiler strips are irregularly arranged on the upper end surface of the main body.

[0021] In this solution, the above arrangement reduces the installation accuracy requirements of the spoiler strip and the body, and facilitates processing.

[0022] A pot support comprises a plurality of legs and the energy-gathering ring as described above. The plurality of legs are connected to the energy-gathering ring and are arranged at intervals along the circumference of the energy-gathering ring. The upper ends of the legs are used to abut against the pot.

[0023] Preferably, the foot piece is fixed to the inner circumference of the energy gathering ring.

[0024] In this solution, the above-mentioned setting can design the diameter of the energy-gathering ring to a larger value when the overall space occupied by the pot support is the same, thereby strengthening the flow path of the flue gas, increasing the convection time with the bottom of the pot, ensuring that the flue gas can be fully burned, and reducing carbon monoxide emissions.

[0025] Preferably, the leg piece is provided with a fixing groove, the fixing groove passes through both ends of the leg piece in the thickness direction, and the notch of the fixing groove is provided at the end of the leg piece away from the center of the energy focusing ring in the radial direction of the energy focusing ring;

[0026] The energy gathering ring is partially arranged in the fixing groove, the upper end surface of the energy gathering ring abuts against the upper groove wall of the fixing groove, and the lower end surface of the energy gathering ring abuts against the lower groove wall of the fixing groove.

[0027] In this solution, the connection between the foot piece and the energy gathering ring is achieved through the cooperation of the fixing groove and the energy gathering ring. The fixing groove can limit the movement of the energy gathering ring in the vertical and horizontal directions to ensure the stability of the pot bracket during use.

[0028] The positive progressive effect of the present invention is that the spoiler strip can change the flow direction of the smoke, increase the disturbance of the airflow, and increase the time that the smoke hovers above the main body of the energy gathering ring, so that the smoke has more time to burn, ensuring that the smoke can be fully burned and reducing carbon monoxide emissions.

[0048] The present invention will be further described below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0049] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0050] like Figure 1 As shown, this embodiment discloses a stove, which is a gas stove that uses liquefied gas or natural gas to generate an open flame and is used for cooking. The stove includes a burner 1, a pot support 2, and a liquid dripping pan 3. The pot support 2 and the liquid dripping pan 3 are both mounted on the outer periphery of the burner 1, and the pot support 2 is placed on the liquid dripping pan 3.

[0051] like Figure 1 and Figure 2 As shown, the burner 1 includes an inner ring fire cover 11, an outer ring fire cover 12, an inner ring gas mixing chamber 13, and an outer ring gas mixing chamber 14. The outer ring fire cover 12 is concentrically mounted radially outside the inner ring fire cover 11. The inner ring gas mixing chamber 13 is fixed to the lower end of the inner ring fire cover 11, and the outer ring gas mixing chamber 14 is fixed to the lower end of the outer ring fire cover 12. The inner ring fire cover 11, the outer ring fire cover 12, the inner ring gas mixing chamber 13, and the outer ring gas mixing chamber 14 are all circular structures. The inner ring fire cover 11 and the outer ring fire cover 12 are each provided with multiple flame holes to generate flames. The pot support 2 is concentrically mounted radially outside the outer ring fire cover 12 to support the pot and improve the combustion efficiency of the flame.

[0052] like Figure 1 、 Figure 3 and Figure 4 As shown, the pot support 2 includes a focusing ring 21 and legs 22. In this embodiment, the focusing ring 21 is a solid, annular structure that improves the combustion efficiency of the flame. The legs 22 are fixed to the focusing ring 21 to support the pot and place the pot support 2 as a whole on the liquid tray 3.

[0053] In other alternative embodiments, the energy gathering ring 21 may also be a hollow structure, and the cavity inside the energy gathering ring 21 can gather high-temperature flue gas, keep warm and insulate, reduce heat loss, and improve combustion thermal efficiency.

[0054] like Figure 3 and Figure 4 As shown, the energy focusing ring 21 includes a body 211 and a spoiler strip 212 .

[0055] Specifically, if Figure 3 and Figure 4 As shown, the body 211 in this embodiment is an annular structure, and the body 211 is concentrically sleeved on the outer peripheral side of the outer ring fire cover 12. In this embodiment, the inner periphery of the body 211 is circular, and the outer periphery of the body 211 is square, that is, the inner periphery of the body 211 is circular, and the outer periphery of the body 211 is square. All turning points of the body 211 adopt arc transitions, and the four corners of the square periphery are rounded.

[0056] Compared with the energy-gathering ring 21 with a circular structure as the outer periphery, when the square outer periphery uses the same value as the side length, the length of its four corners is greater than the length of the circular radius, that is, the diagonal length of the square is greater than the radius length of the circle. The smoke generated by the fire cover has a longer flow path in the diagonal direction of the square, which increases the convection time with the bottom of the pot, ensures that the smoke can be fully burned, and reduces carbon monoxide emissions. The shape of the inner periphery is a circle that matches the shape of the fire cover and the mixing chamber, which can enhance the extensibility of the flame and is conducive to combustion. At the same time, the circular inner periphery can surround the entire burner 1, giving the smoke a relatively semi-sealed environment and gathering the smoke. When the flame radiates heat outward, the smoke is accompanied by secondary air and has a stronger ability to combine with the burning flame, thereby improving the thermal efficiency of the stove.

[0057] like Figure 3 and Figure 4 As shown, the spoiler strip 212 is provided on the upper end surface of the main body 211 and protrudes upward from the upper end surface of the main body 211. In this embodiment, the spoiler strip 212 is in the shape of an elongated strip, and the length direction of the spoiler strip 212 intersects with the first direction (the first direction is the direction passing through the spoiler strip 212 in the radial direction of the energy focusing ring 21) on the horizontal plane. When the stove burns, high-temperature smoke will overflow radially outward from the fire cover along with the flame. When the smoke passes through the spoiler strip 212, since the length direction of the spoiler strip 212 intersects with the original flow direction of the smoke, the spoiler strip 212 can change the flow direction of the smoke, increase the disturbance of the airflow, and increase the time that the smoke hovers above the main body 211 of the energy focusing ring 21, so that the smoke has more time to burn, ensuring that the smoke can be fully burned and reducing carbon monoxide emissions.

[0058] Figure 4The first direction corresponding to one of the spoiler strips 212 is shown. It should be noted that the first directions corresponding to different spoiler strips 212 are not necessarily the same or different, and should be determined specifically based on the position of the spoiler strip 212 .

[0059] Furthermore, if Figure 3 and Figure 4 As shown, both ends of the spoiler strip 212 in the longitudinal direction are arc-shaped to facilitate the flow of smoke. The spoiler strip 212 has an arc-shaped structure and bends in a first direction away from the center of the energy focusing ring 21, further increasing the residence time of the smoke, allowing the smoke more time to burn, ensuring that the smoke can burn fully and reducing carbon monoxide emissions.

[0060] The degree of curvature of the spoiler strip 212 is relatively small. While being able to increase the smoke residence time to a certain extent, it will not excessively block the gas from flowing radially outward from the energy-gathering ring 21 , thereby ensuring safety during use.

[0061] like Figure 3 and Figure 4 As shown, the spoiler strips 212 are disposed at the four corners of the body 211. Since the inner periphery of the body 211 is circular and the outer periphery of the body 211 is square, the four corners of the body 211 provide more installation space for the spoiler strips 212, facilitating the arrangement and installation of the spoiler strips 212. In other alternative embodiments, the spoiler strips 212 may also be installed at other locations on the body 211.

[0062] Furthermore, if Figure 3 and Figure 4 As shown, multiple spoiler strips 212 are provided at each corner to enhance the flue gas disturbance effect and increase the time the flue gas hovers above the main body 211 of the energy-gathering ring 21, allowing the flue gas more time to burn, ensuring sufficient combustion and reducing carbon monoxide emissions. The multiple spoiler strips 212 at the same corner are independent of each other, and gas flow channels are formed between the multiple spoiler strips 212, allowing the gas to flow radially outward from the energy-gathering ring 21, ensuring safety during use.

[0063] The number of spoiler strips 212 at different corners can be the same or different. Figure 4 As shown, in this embodiment, three spoiler strips 212 are provided at two corners of the body 211, and two spoiler strips 212 are provided at the other two corners of the body 211. In other alternative embodiments, the number of spoiler strips 212 provided on the body 211 can be designed based on actual conditions.

[0064] like Figure 4As shown, in this embodiment, for multiple spoiler strips 212 located at the same corner, the spoiler strips 212 are irregularly arranged on the upper end surface of the main body 211 to reduce the installation accuracy requirements of the spoiler strips 212 and the main body 211 and facilitate processing. In other alternative embodiments, the positions of the spoiler strips 212 can also be designed regularly according to needs.

[0065] like Figure 3-Figure 5 As shown, in this embodiment, there are multiple legs 22, specifically four. Multiple pot supports 2 are spaced apart circumferentially around the energy-gathering ring 21, with the legs 22 fixed to the inner circumference of the energy-gathering ring 21. This allows the diameter of the energy-gathering ring 21 to be designed to be larger while maintaining the same overall footprint of the pot supports 2. This strengthens the flue gas flow path, increases convection time with the bottom of the pot, ensures adequate combustion of the flue gas, and reduces carbon monoxide emissions. In this embodiment, the legs 22 are fixed to the four edges of the body 211 to avoid the spoiler strips 212.

[0066] Specifically, if Figure 5 and Figure 6 As shown, a fixing groove 221 is provided in the middle of the leg piece 22. The shape of the fixing groove 221 matches the shape of the inner circumference of the main body 211. The fixing groove 221 runs through both ends of the leg piece 22 in the thickness direction. The notch of the fixing groove 221 is provided at the end of the leg piece 22 that is away from the center of the energy focusing ring 21 in the radial direction of the energy focusing ring 21. The energy focusing ring 21 is partially provided in the fixing groove 221. The upper end surface of the energy focusing ring 21 abuts against the upper groove wall of the fixing groove 221, and the lower end surface of the energy focusing ring 21 abuts against the lower groove wall of the fixing groove 221. The upper end of the leg piece 22 is higher than the energy focusing ring 21 so as to abut against the bottom of the cookware. The lower end of the leg piece 22 is lower than the energy focusing ring 21 and is mounted on the liquid receiving tray 3.

[0067] In this embodiment, the connection between the foot piece 22 and the energy gathering ring 21 is achieved by the cooperation between the fixing groove 221 and the energy gathering ring 21. The fixing groove 221 can limit the movement of the energy gathering ring 21 in the vertical and horizontal directions, thereby ensuring the stability of the pot support 2 during use.

[0068] In other alternative embodiments, the foot piece 22 may also be fixed to the outer periphery of the energy focusing ring 21 .

[0069] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate the orientation or position relationship of the device or component during normal use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation at any time. Therefore, they should not be understood as limiting the present invention in this regard.
