Pot rack and stove

Abstract

This application provides a pot rack and stove, relating to the field of kitchenware technology. The pot rack includes a ring-shaped component and a support assembly. The inner ring surface of the ring-shaped component includes an inclined surface, which is inclined outward relative to the central axis of the ring-shaped component. The support assembly is disposed on the ring-shaped component. In the pot rack of this application, the inclined surface causes high-temperature flue gas to rush upward at an angle towards the bottom of the pot. Compared with existing pot racks that rush vertically upward towards the bottom of the pot, the pot rack of this application reduces the resistance encountered by the high-temperature flue gas when it is discharged into the atmosphere, increasing the speed at which the high-temperature flue gas is discharged into the atmosphere. Driven by the high-temperature flue gas, the speed at which the secondary air required for combustion enters the burner through the second gap is also increased, thereby improving the kinetic energy of the secondary air required for combustion, resulting in more complete combustion and thus improving the thermal efficiency of the burner.

Description

Technical Field

[0001] This application relates to the field of kitchenware technology, and in particular to a pot rack and stove. Background Technology

[0002] As an essential kitchen cooking appliance in daily family life, high combustion thermal efficiency has become one of the development directions for gas stoves.

[0003] Gas stoves are equipped with pot supports to support cookware so that the burners on the gas stove can heat the cookware. The pot supports are arranged around the burners. In order to improve combustion thermal efficiency, some gas stoves in the prior art use pot supports with a ring structure. The ring structure can concentrate the flame of the burner, thereby reducing the heat diffusion of the burner to the surroundings and improving the heating efficiency of the burner on the cookware.

[0004] However, the existing ring-shaped boiler frame results in excessive resistance to the high-temperature flue gas emission from the burner, leading to a decrease in the emission rate of the high-temperature flue gas. Utility Model Content

[0005] This application provides a pot rack and a stove to solve the technical problem that existing pot racks with ring structures cause excessive resistance to high-temperature flue gas emissions from the burner.

[0006] A first aspect of this application provides a pot rack, comprising:

[0007] An annular component, wherein the inner annular surface of the annular component includes an inclined surface, the inclined surface being inclined outward relative to the central axis of the annular component, and the diameter of the inclined surface near the first end face of the annular component is greater than the diameter of the inclined surface near the second end face of the annular component;

[0008] A support assembly is disposed on the annular member. One end of the support assembly extends along the central axis to the outer side of the first end face to support the cookware and to form a first gap between the first end face and the cookware so that the high-temperature flue gas generated by the burner of the stove can be transmitted. A second gap is provided between the second end face and the panel of the stove, and the second gap is used to supplement air to the burner.

[0009] In one possible implementation, the inner annular surface of the annular member further includes a vertical surface, which is disposed at one end of the inclined surface near the second end face.

[0010] In one possible implementation, the height of the inner annular surface along the central axis is a first height, and the height of the inclined surface along the central axis is a second height, wherein the second height is greater than or equal to 0.55 times the first height and less than or equal to 0.65 times the first height.

[0011] In one possible implementation, the height of the inner annular surface along the central axis is a first height, and the height of the vertical surface along the central axis is a third height, wherein the third height is greater than or equal to 0.35 times the first height and less than or equal to 0.45 times the first height.

[0012] In one possible implementation, the angle between the inclined surface and the central axis is greater than or equal to 20° and less than or equal to 30°.

[0013] In one possible implementation, the thickness of the annular member is greater than or equal to 8 mm and less than or equal to 12 mm.

[0014] In one possible implementation, a chamfer is provided at the connection between the outer side of the second end face and the outer annular surface, and the radius of the chamfer is less than or equal to 3 mm.

[0015] In one possible implementation, the support assembly is disposed on the vertical surface, with one end of the support assembly away from the cookware extending along the central axis to the outside of the second end face, so as to be disposed on the panel and to form the second gap between the second end face and the panel.

[0016] In one possible implementation, the support assembly includes a plurality of support feet, each of which is disposed on the vertical surface and is circumferentially spaced along the inner annular surface.

[0017] A second aspect of this application provides a stove, including a stove body and a pot rack as described in any of the above embodiments, the pot rack being disposed on the stove body.

[0018] This application provides a pot rack and a stove. The pot rack includes a ring-shaped component and a support assembly. The inner ring surface of the ring-shaped component includes an inclined surface that is inclined outward relative to the central axis of the ring-shaped component. The diameter of the inclined surface near the first end face of the ring-shaped component is larger than the diameter of the inclined surface near the second end face of the ring-shaped component. The support assembly is disposed on the ring-shaped component. One end of the support assembly extends along the central axis to the outside of the first end face to support the pot and form a first gap between the first end face and the pot to allow the high-temperature flue gas generated by the burner of the stove to be transmitted. A second gap is provided between the second end face and the panel of the stove, and the second gap is used to supplement air to the burner. When using a pot rack, it needs to be placed on the stove. At this time, the central axis of the annular component is in the vertical direction. Because the inner ring surface of the annular component includes an inclined surface, which is inclined outward relative to the central axis of the annular component, the inner diameter of the upper end of the annular component is larger than the inner diameter of the lower end. The inclined surface has a guiding effect on the high-temperature flue gas generated by the burner, causing the high-temperature flue gas to flow upward along the inner ring of the annular component towards the bottom of the pot, and finally be discharged into the atmosphere from the first gap. Therefore, compared with the existing pot racks that are vertically upward and directly rush to the bottom of the pot, the pot rack of this application reduces the resistance encountered by the high-temperature flue gas when it is discharged into the atmosphere, thus improving the efficiency of high-temperature flue gas discharge. The increased velocity of the flue gas released into the atmosphere, coupled with the increased speed of the high-temperature flue gas, also increases the velocity of the secondary air required for combustion entering the burner through the second gap. This enhances the kinetic energy of the secondary air needed for combustion, resulting in more complete combustion, improved overall combustion conditions, and increased thermal efficiency. Furthermore, the upward tilt of the high-temperature flue gas towards the bottom of the cookware allows it to circulate to the upper edge of the bottom, increasing the contact area between the bottom and the flue gas and further improving the heating efficiency of the cookware.

[0037] As an essential kitchen cooking appliance in daily family life, high combustion thermal efficiency has become one of the development directions for gas stoves.

[0038] Gas stoves are equipped with pot supports to support cookware so that the burners on the gas stove can heat the cookware. The pot supports are arranged around the burners. In order to improve combustion thermal efficiency, some gas stoves in the prior art use pot supports with a ring structure. The ring structure can concentrate the flame of the burner, thereby reducing the heat diffusion of the burner to the surroundings and improving the heating efficiency of the burner on the cookware.

[0039] The upper end of the ring structure is used to discharge the high-temperature flue gas generated by the burner, and the lower end of the ring structure is used to replenish the secondary air required for combustion. Because the upper end of the ring structure is vertically aligned with the bottom of the pot, the high-temperature flue gas generated by the burner rises vertically straight to the bottom of the pot, resulting in excessive resistance to the discharge of the high-temperature flue gas. This reduces the discharge speed of the high-temperature flue gas, thereby reducing the kinetic energy required for the replenishment of secondary air for combustion. Consequently, the combustion is incomplete, resulting in poor overall combustion conditions and low thermal efficiency of the burner.

[0040] To address the technical problem of excessive resistance to high-temperature flue gas emissions from burners caused by existing ring-shaped pot supports, this application proposes a pot support and a stove. The pot support includes a ring-shaped component and a support assembly. The inner ring surface of the ring-shaped component includes an inclined surface that is inclined outward relative to the central axis of the ring-shaped component. The diameter of the inclined surface near the first end face of the ring-shaped component is larger than the diameter of the inclined surface near the second end face of the ring-shaped component. The support assembly is disposed on the ring-shaped component, with one end extending along the central axis to the outside of the first end face to support the pot and form a first gap between the first end face and the pot to allow the high-temperature flue gas generated by the burner of the stove to be transmitted. A second gap is provided between the second end face and the panel of the stove, and the second gap is used to supplement air to the burner.

[0041] In the pot rack of this application, when the pot rack is used and placed on the stove, the central axis of the annular component is oriented vertically. This is because the inner ring surface of the annular component includes an inclined surface that slopes outward relative to the central axis, making the upper inner diameter of the annular component larger than the lower inner diameter. The inclined surface guides the high-temperature flue gas generated by the burner, causing the high-temperature flue gas to flow upwards along the inner ring towards the outer ring towards the bottom of the pot, and finally exit into the atmosphere through the first gap. Therefore, compared to existing pot racks that vertically upwards directly towards the bottom of the pot, the pot rack of this application reduces the resistance encountered by the high-temperature flue gas when exiting into the atmosphere, thus improving efficiency. The increased velocity of the high-temperature flue gas into the atmosphere, driven by the flue gas, also increases the velocity of the secondary air required for combustion entering the burner through the second gap. This enhances the kinetic energy of the secondary air supply, resulting in more complete combustion, improved overall combustion conditions, and increased thermal efficiency. Furthermore, the upward-sloping high-temperature flue gas reaches the bottom of the cookware, increasing the contact area between the bottom and the flue gas, thus improving heating efficiency.

[0042] The technical solution of the application will be described in detail below with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0043] Reference Figures 1 to 4 As shown, Figure 1 A schematic diagram of the structure of the pot rack provided for an embodiment of this application; Figure 2 for Figure 1 A structural diagram from another angle; Figure 3 A cross-sectional structural diagram of the pot rack provided for an embodiment of this application; Figure 4This is a schematic diagram of a stove with a pot mounted on it, provided as an embodiment of this application.

[0044] In the embodiments of this application, reference is made to Figure 1 , Figure 3 and Figure 4 As shown, a first aspect of the present application provides a pot rack, including an annular member 100 and a support assembly 200.

[0045] The inner annular surface 110 of the annular member 100 includes an inclined surface 111, which is inclined outward relative to the central axis of the annular member 100, and the diameter of the inclined surface 111 near the first end face 120 of the annular member 100 is greater than the diameter of the inclined surface 111 near the second end face 130 of the annular member 100.

[0046] A support component 200 is disposed on the annular member 100. One end of the support component 200 extends along the central axis to the outer side of the first end face 120 to support the cookware 10 and to form a first gap 300 between the first end face 120 and the cookware 10 so that the high-temperature flue gas generated by the burner 21 of the stove 20 can be transmitted. A second gap 400 is provided between the second end face 130 and the panel of the stove 20. The second gap 400 is used to supplement air to the burner 21.

[0047] It should be noted that when using the pot rack, it is necessary to place the pot rack on the stove 20. At this time, the direction of the central axis of the annular part 100 is the up and down direction.

[0048] In the pot rack of this application embodiment, the ring-shaped member 100 can be a circular ring structure, a rectangular ring structure, an elliptical ring structure, a triangular ring structure, a fan-shaped ring structure, etc. In this embodiment, it is only necessary to ensure that the middle part of the ring-shaped member 100 has a clearance hole so as to avoid the burner 21 of the stove 20.

[0049] The inner ring surface 110 of the ring member 100 includes an inclined surface 111. The inner ring surface 110 may only have an inclined surface 111, or the inner ring surface 110 may include other surfaces in addition to the inclined surface 111, such as a vertical surface 112, a concave-convex surface, a wedge-shaped surface, etc. In this embodiment, the inclined surface 111 forms the inner ring surface 110 of the ring member 100.

[0050] The upper end face of the annular member 100 is the first end face 120, and the lower end face of the annular member 100 is the second end face 130.

[0051] A support component 200 is disposed on the annular member 100. The upper end of the support component 200 is used to support the cookware 10, supporting the cookware 10 above the burner 21. One end of the support component 200 extends along the central axis to the outside of the first end face 120 of the annular member 100, that is, the upper end of the support component 200 is higher than the upper end of the annular member 100, thereby forming a first gap 300 between the upper end of the annular member 100 and the cookware 10. The high-temperature flue gas generated by the burner 21 will be discharged into the atmosphere through the first gap 300. During the discharge process, the high-temperature flue gas will heat the bottom surface of the cookware 10. A second gap 400 is provided between the second end face 130 of the annular member 100 and the panel of the stove 20. The secondary air required for combustion of the burner 21 can enter the burner 21 through the second gap 400.

[0052] It should be noted that the second gap 400 can be formed by providing a through hole or channel on the second end face 130, or by supporting the annular member 100 with other support members, so that the second end face 130 and the panel of the stove 20 are formed with the second gap 400, for example by supporting the support component 200.

[0053] The inclined surface 111 is inclined from bottom to top, from the inner ring of the annular member 100 to the outer ring of the annular member 100. This results in the inner diameter of the annular member 100 at the bottom of the inclined surface 111 being smaller than the inner diameter of the annular member 100 at the top of the inclined surface 111. Consequently, the inner diameter of the upper end of the annular member 100 is larger than the inner diameter of the lower end of the annular member 100. The inner ring surface 110 of the annular member 100 has a guiding effect on the high-temperature flue gas generated by the combustion of the burner 21 within the inner ring of the annular member 100. The high-temperature flue gas will flow along... The flue gas flows upward along the inclined surface 111 and is finally discharged from the first gap 300 to the outer ring of the annular member 100, that is, into the atmosphere. Compared with the existing pot rack that flows vertically upward to the bottom of the pot 10, the high-temperature flue gas of this application flows upward along the inclined surface 111 and will not flow vertically upward to the bottom of the pot 10. Instead, it will flow upward at an angle along the inclined surface 111 to the bottom of the pot 10, thereby reducing the resistance encountered by the high-temperature flue gas in the atmosphere and increasing the speed at which the high-temperature flue gas is discharged into the atmosphere.

[0054] In the pot rack of this application, the inclined surface 111 is inclined outward relative to the central axis of the annular member 100, such that the inner diameter of the upper end of the annular member 100 is larger than the inner diameter of the lower end of the annular member 100. The inclined surface 111 has a guiding effect on the high-temperature flue gas generated by the burner 21, causing the high-temperature flue gas to flow upward along the inner ring of the annular member 100 towards the bottom of the pot 10, and finally discharged into the atmosphere from the first gap 300. Therefore, compared with the existing pot racks that flow vertically upward directly to the bottom of the pot 10, the pot rack of this application reduces the resistance encountered by the high-temperature flue gas when it is discharged into the atmosphere, increases the speed at which the high-temperature flue gas is discharged into the atmosphere, and because the high-temperature flue gas... As the emission velocity into the atmosphere increases, the secondary air required for combustion in burner 21 also enters burner 21 through the second gap 400 at an increased velocity driven by the high-temperature flue gas. This increases the replenishment kinetic energy of the secondary air required for combustion in burner 21, resulting in more complete combustion and improved overall combustion conditions. Consequently, the thermal efficiency of burner 21 is improved. Furthermore, because the high-temperature flue gas flows upwards towards the bottom surface of cookware 10, it can circulate to the upper edge of the bottom surface of cookware 10, thereby increasing the contact area between the bottom surface of cookware 10 and the high-temperature flue gas, thus improving the heating efficiency of cookware 10.

[0055] Furthermore, the annular component 100 is a circular ring.

[0056] In this embodiment, the annular component 100 is a circular ring, with both the inner and outer rings being circular, thereby improving the focusing effect of the combustion flame of the burner 21.

[0057] In some embodiments, the inner annular surface 110 of the annular member 100 further includes a vertical surface 112, which is disposed at one end of the inclined surface 111 near the second end surface 130.

[0058] In this embodiment, the inner annular surface 110 of the annular member 100 includes an inclined surface 111 and a vertical surface 112 connected vertically, that is, the inclined surface 111 is located above the vertical surface 112. In this embodiment, the inclined surface 111 and the vertical surface are combined to form the inner annular surface 110 of the annular member 100. The vertical surface 112 can concentrate the combustion flame of the burner 21.

[0059] In other embodiments, the height of the inner annular surface 110 along the central axis is a first height, and the height of the inclined surface 111 along the central axis is a second height, wherein the second height is greater than or equal to 0.55 times the first height and less than or equal to 0.65 times the first height.

[0060] It should be noted that when using the pot rack, the pot rack needs to be placed on the stove 20. At this time, the direction of the central axis of the annular part 100 is the up and down direction, and the height of the inner annular surface 110 along the central axis and the height of the inclined surface 111 along the central axis are both vertical heights.

[0061] Reference Figure 3 As shown, the first height is H, and the second height is H1, where H1 = 0.55H~0.65H.

[0062] In this embodiment, the vertical height of the inclined surface 111 is greater than half the vertical height of the entire inner ring surface 110, but not too large. This ensures that the inclined surface 111 has a certain gathering effect, while also ensuring that the guiding path of the inclined surface 111 is appropriate, thus preventing high-temperature flue gas from directly hitting the bottom of the pot 10.

[0063] In another embodiment, the height of the inner annular surface 110 along the central axis is the first height, and the height of the vertical surface 112 along the central axis is the third height. The third height is greater than or equal to 0.35 times the first height and less than or equal to 0.45 times the first height.

[0064] Reference Figure 3 As shown, the first height is H, and the third height is H2, where H2 = 0.35H~0.45H.

[0065] In this embodiment, the vertical height of the vertical surface 112 is less than half the vertical height of the entire inner ring surface 110, and it cannot be too small. This ensures that the vertical surface 112 has a certain gathering effect, while avoiding an excessively long flow path of the vertical surface 112, which would cause the high-temperature flue gas to directly hit the bottom of the cookware 10.

[0066] In another possible embodiment, the angle between the inclined surface 111 and the central axis is greater than or equal to 20° and less than or equal to 30°.

[0067] Reference Figure 3 As shown, the angle between the inclined surface 111 and the central axis is 20°~30°.

[0068] In this embodiment, the angle between the inclined surface 111 and the central axis is . Figure 3 As shown in the figure, A is 20°~30°, which ensures that the inclined surface 111 has a certain gathering effect on the high-temperature flue gas and flame, and also ensures that the guiding path of the inclined surface 111 is appropriate, so as to prevent the high-temperature flue gas from directly hitting the bottom of the pot 10.

[0069] In another embodiment, the thickness of the annular member 100 is greater than or equal to 8 mm and less than or equal to 12 mm.

[0070] In this embodiment, refer to Figure 3As shown, the thickness of the annular member 100 is the radial width of the first end face 120, which is 8mm to 12mm.

[0071] It should be noted that the upper end of the annular member 100 is the first end face 120, and the lower end of the annular member 100 is the second end face 130. There is a first gap 300 between the first end face 120 and the bottom surface of the pot 10. A guide channel is formed at the first gap 300. The guide channel is connected to the burner 21 to discharge the high-temperature flue gas generated by the burner 21.

[0072] In this embodiment, the first end face 120 and the bottom surface of the pot 10 form a flow channel. The flow channel can slow down the flow rate of the high-temperature flue gas when it flows to this point and make it evenly and stably adhere to the bottom of the pot 10. This strengthens the effective contact between the high-temperature flue gas and the bottom of the pot, prolongs the contact time between the high-temperature flue gas and the bottom of the pot, enhances the heat exchange effect, effectively improves the thermal energy utilization rate, and thus improves the combustion thermal efficiency.

[0073] The thickness of the annular member 100 is Figure 3 As shown in the diagram, in order to achieve better results, the radial width of the first end face 120 is 8mm~12mm, which prolongs the contact time between the high-temperature flue gas and the bottom of the pot, and avoids the guide channel path being too long, thus affecting the emission speed.

[0074] In some possible embodiments, a chamfer is provided at the connection between the outer side of the second end face 130 and the outer ring face 140, and the radius of the chamfer is less than or equal to 3 mm.

[0075] In this embodiment, the radius of the chamfer is Figure 3 As shown in the figure, R should be controlled within a radius of ≤3mm, because if it is too large, the flow rate of the secondary air will be too fast, which will affect the preheating effect of the secondary air and the high-temperature flue gas.

[0076] Furthermore, the chamfer is rounded.

[0077] In this embodiment, the rounded corners allow secondary air to enter the chamfer more smoothly and prevent damage to the chamfer under long-term use, thus improving the lifespan of the chamfer.

[0078] In other embodiments, the end of the support component 200 away from the cookware 10 extends along the central axis to the outside of the second end face 130 to be disposed on the panel, and a second gap 400 is formed between the second end face 130 and the panel.

[0079] In this embodiment, the end of the support component 200 away from the cookware 10 extends along the central axis to the outside of the second end face 130, that is, the lower end of the support component 200 is lower than the lower end of the annular member 100. The lower end of the support component 200 is used to be mounted on the panel of the stove 20, thereby forming a second gap 400 between the lower end of the annular member 100 and the panel. The second gap 400 is used to supplement air to the burner 21. This supplemented air is the secondary air required for combustion in the burner 21.

[0080] In another possible embodiment, the support assembly 200 includes a plurality of support feet 210, each of which is disposed on the vertical surface 112 and is distributed circumferentially along the inner ring surface 110.

[0081] In this embodiment, each support foot 210 is arranged on a vertical surface 112, which makes it easier to weld and assemble with each support foot 210, thereby improving production efficiency.

[0082] Furthermore, each support foot 210 is evenly spaced along the circumference of the inner ring surface 110.

[0083] In this embodiment, the force on the annular member 100 is more uniform, thereby improving the stability of the annular member 100.

[0084] Furthermore, the number of support feet 210 is 4.

[0085] In this embodiment, the stability of the annular member 100 on the surface of the stove 20 is further improved.

[0086] In other embodiments, the outer ring surface 140, the first end face 120, the inner ring surface 110, and the second end face 130 of the annular member 100 together enclose to form a sealed heat insulation cavity 500.

[0087] In this embodiment, the sealed heat insulation cavity 500 helps to keep the combustion heat energy gas mass around the burner 21 warm, reduces the heat dissipation to the outside, and effectively reduces heat loss.

[0088] The sealed heat insulation cavity 500 can be filled with gas or a vacuum.

[0089] Furthermore, the sealed heat insulation cavity 500 is filled with gas.

[0090] In this embodiment, the gas can be an inert gas, dry air, nitrogen, etc.

[0091] A second aspect of this application provides a stove 20, including a stove body and a pot rack as described in any of the above embodiments, the pot rack being disposed on the stove body.

[0092] Since the stove of this embodiment is specifically provided with the pot rack of this embodiment, the pot rack includes an annular member 100 and a support assembly 200. The inner annular surface 110 of the annular member 100 includes an inclined surface 111. The inclined surface 111 is inclined outward relative to the central axis of the annular member 100, and the diameter of the inclined surface 111 near the first end face 120 of the annular member 100 is larger than the diameter of the inclined surface 111 near the second end face 130 of the annular member 100. The support assembly 200 is disposed on the annular member 100. One end of the support assembly 200 extends along the central axis to the outside of the first end face 120 to support the pot 10, and a first gap 300 is formed between the first end face 120 and the pot 10 so that the high-temperature flue gas generated by the burner 21 of the stove 20 can be transmitted. A second gap 400 is provided between the second end face 130 and the panel of the stove 20. The second gap 400 is used to supplement air to the burner 21.

[0093] In the stove 20 of this application, because the inclined surface 111 is inclined outward relative to the central axis of the annular member 100, the inner diameter of the upper end of the annular member 100 is larger than the inner diameter of the lower end of the annular member 100. The inclined surface 111 has a guiding effect on the high-temperature flue gas generated by the burner 21, causing the high-temperature flue gas to flow upward along the inner ring of the annular member 100 towards the bottom of the pot 10, and finally be discharged into the atmosphere from the first gap 300. Therefore, compared with the existing pot racks that are vertically upward and directly rush to the bottom of the pot 10, the pot rack of this application... The resistance encountered by the high-temperature flue gas in the atmosphere is reduced, increasing the velocity of the high-temperature flue gas in the atmosphere. As the velocity of the high-temperature flue gas in the atmosphere increases, the velocity of the secondary air required for combustion in burner 21 through the second gap 400 also increases under the influence of the high-temperature flue gas. This further enhances the kinetic energy of the secondary air required for combustion in burner 21, making combustion in burner 21 more complete, improving the overall combustion conditions, and thus improving the thermal efficiency of burner 21.
