Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils, and in particular to a pot support and a stove. Background Technology

[0002] To improve thermal efficiency, existing cooktops typically have a heat-concentrating ring on the pot support to reduce heat loss.

[0003] However, when external air enters the gas stove to provide oxygen for fuel combustion, the air temperature is usually room temperature, which differs significantly from the ignition temperature of the gas, making it impossible to effectively preheat the secondary air. Simultaneously, due to heat conduction and radiation, some heat is lost during combustion, reducing combustion efficiency. Furthermore, the existing energy-concentrating ring structure lacks aesthetic appeal. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the deficiency of the weak energy-concentrating effect of the existing pot support, and to provide a pot support and stove.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A pot support, comprising: a hollow energy-concentrating ring;

[0007] The energy-concentrating ring is provided with a preheating channel and a heat-insulating cavity. The preheating channel is connected to the inner and outer circumferences of the energy-concentrating ring, respectively, and is located above the heat-insulating cavity.

[0008] In this design, the boiler support has a preheating channel. Cold air from the outer periphery of the energy-concentrating ring enters the inner periphery of the energy-concentrating ring through the preheating channel. When passing through the preheating channel, the air is preheated by the insulation cavity below the preheating channel. The preheated high-temperature flue gas participates in combustion again, increasing the temperature of the secondary air and thus improving the thermal efficiency of the burner on the inner periphery of the boiler support.

[0009] Preferably, the energy-concentrating ring is disc-shaped.

[0010] In this scheme, the energy-concentrating ring is disc-shaped, so the high-temperature gas on the inner periphery of the energy-concentrating ring can flow along the upper surface of the energy-concentrating ring due to the wall effect, collide and merge with the cold air in a specific area, preheat the cold air, and the preheated high-temperature flue gas participates in combustion again, increasing the temperature of the secondary air.

[0011] Preferably, the cross-sectional shape of the upper surface of the energy-concentrating ring is streamlined.

[0012] In this scheme, since the cross-sectional shape of the upper surface of the energy-concentrating ring is streamlined, it is easier for the high-temperature gas on the inner periphery of the energy-concentrating ring to flow along the upper surface of the energy-concentrating ring to the outer periphery.

[0013] Preferably, the cross-sectional shape of the preheating channel is the same as the cross-sectional shape of the upper surface of the energy-concentrating ring.

[0014] In this scheme, since the cross-sectional shape of the preheating channel is the same as the cross-sectional shape of the upper surface of the energy-concentrating ring, the high-temperature gas on the inner circumference of the energy-concentrating ring overflows from the inner circumference to the outer circumference and then flows from the outer circumference to the inner circumference through the preheating channel with the same cross-sectional shape.

[0015] Preferably, the energy-concentrating ring includes an upper shell, a middle shell, and a lower shell arranged sequentially from top to bottom;

[0016] The preheating channel is formed between the upper shell and the middle shell.

[0017] Preferably, at least a portion of the insulation cavity is formed between the middle shell and the lower shell.

[0018] Preferably, the middle plate shell includes an inclined plate and a groove located on the outer periphery of the inclined plate, the groove being recessed downwards;

[0019] The preheating channel is formed between the inclined plate and the upper shell, and the heat preservation cavity is formed in the groove.

[0020] In this design, the middle plate shell is provided with a groove to form an L-shaped cross section, which facilitates the installation of the middle plate shell and the lower plate shell.

[0021] Preferably, the cross-section of the inner circumferential port of the preheating channel gradually narrows towards the inner circumferential side.

[0022] In this scheme, since the cross-section of the inner circumferential port of the preheating channel gradually narrows towards the inner circumferential side to form a nozzle structure, it is beneficial for the gas on the outer circumferential side of the energy-concentrating ring to be introduced into the inner circumferential side of the energy-concentrating ring through the preheating channel.

[0023] Preferably, the width of the port on the outer periphery of the preheating channel is greater than the width of the port on the inner periphery of the preheating channel.

[0024] In this design, the preheating channel is designed with a large inlet and a small outlet, which facilitates the introduction of gas from the outer periphery of the energy-concentrating ring into the inner periphery of the energy-concentrating ring through the preheating channel.

[0025] A cooktop that includes a pot support as described above.

[0026] The positive and progressive effects of this utility model are as follows: the pot support has a preheating channel, the cold air on the outer periphery of the energy-concentrating ring enters the inner periphery of the energy-concentrating ring through the preheating channel, and is preheated by the heat preservation cavity below the preheating channel when passing through the preheating channel. The preheated high-temperature flue gas participates in combustion again, which increases the temperature of the secondary air, thereby improving the thermal efficiency of the burner on the inner periphery of the pot support.

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and by way of embodiments, but the present invention is not limited to the scope of the embodiments thereon.

[0034] like Figure 1-5 As shown, this embodiment provides a pot support 100, which includes a hollow energy-concentrating ring 120 and corner pieces 110.

[0035] In this embodiment, the corner piece 110 is sheet-shaped and inserted into the energy-concentrating coil 120. However, the present invention is not limited to this, and the corner piece 110 can also be other existing structures, such as a columnar structure welded to the energy-concentrating coil 120.

[0036] The energy-concentrating ring 120 is provided with a preheating channel 125 and a heat-insulating cavity 127. The preheating channel 125 is connected to the inner and outer circumferences of the energy-concentrating ring 120 respectively, and the preheating channel 125 is located above the heat-insulating cavity 127.

[0037] The boiler support 100 has a preheating channel 125. Cold air from the outer periphery of the energy-concentrating ring 120 enters the inner periphery of the energy-concentrating ring 120 through the preheating channel 125. When passing through the preheating channel 125, it is preheated by the heat preservation cavity 127 below the preheating channel 125. The preheated high-temperature flue gas participates in combustion again, which increases the temperature of the secondary air and thus improves the thermal efficiency of the burner on the inner periphery of the boiler support 100.

[0038] The heat-insulating cavity 127 of the energy-concentrating ring 120 will be filled with high-temperature air after the burner on the inner circumference side of the pot support 100 has been burning for a period of time, thus having a preheating effect on the preheating channel 125.

[0039] In this embodiment, the insulation cavity 127 is hollow and without filling material, but the present invention is not limited to this. In other embodiments, the insulation cavity 127 may also be filled with high-temperature resistant insulation material.

[0040] In this embodiment, the energy-concentrating ring 120 is disc-shaped, so that the high-temperature gas on the inner periphery of the energy-concentrating ring 120 can flow along the upper surface of the energy-concentrating ring 120 due to the wall effect, collide and merge with the cold air in a specific area, preheat the cold air, and the preheated high-temperature flue gas participates in combustion again, increasing the temperature of the secondary air.

[0041] The disc-like shape here refers to the fact that the energy-concentrating ring 120 has a flat overall shape.

[0042] Alternatively, the energy-concentrating ring 120 can also be other existing shapes.

[0043] The upper surface of the energy-concentrating ring 120 has a streamlined cross-sectional shape. Because the upper surface of the energy-concentrating ring 120 has a streamlined cross-sectional shape, it is easier for the high-temperature gas on the inner circumference of the energy-concentrating ring 120 to flow along the upper surface of the energy-concentrating ring 120 to the outer circumference of the energy-concentrating ring 120.

[0044] The cross-sectional shape of the preheating channel 125 is the same as that of the upper surface of the energy-concentrating ring 120. Since the cross-sectional shape of the preheating channel 125 is the same as that of the upper surface of the energy-concentrating ring 120, the high-temperature gas on the inner circumference of the energy-concentrating ring 120 overflows from the inner circumference to the outer circumference and then flows from the outer circumference to the inner circumference through the preheating channel 125 with the same cross-sectional shape.

[0045] The energy-concentrating ring 120 includes an upper shell 121, a middle shell 122, and a lower shell 123 arranged sequentially from top to bottom; a preheating channel 125 is formed between the upper shell 121 and the middle shell 122. At least a portion of an insulation cavity 127 is formed between the middle shell 122 and the lower shell 123.

[0046] "Plate shell" refers to a plate-shaped shell.

[0047] The middle plate shell 122 includes an inclined plate and a groove located on the outer periphery of the inclined plate, the groove being recessed downwards; a preheating channel 125 is formed between the inclined plate and the upper plate shell 121, and a heat preservation cavity 127 is formed in the groove.

[0048] The middle plate shell 122 is provided with a groove to form an L-shaped cross section, which facilitates the installation of the middle plate shell 122 and the lower plate shell 123.

[0049] The cross-section of the inner circumferential port portion 1253 of the preheating channel 125 gradually narrows towards the inner circumference. This gradual narrowing of the cross-section of the inner circumferential port portion 1253 of the preheating channel 125 forms a nozzle structure, which facilitates the introduction of gas from the outer circumference of the energy-concentrating ring 120 into the inner circumference of the energy-concentrating ring 120 through the preheating channel 125. The interior of the inner circumferential port portion 1253 of the preheating channel 125 is also formed in a shape that gradually narrows towards the inner circumference, thereby allowing gas to be ejected from the inner circumferential port.

[0050] The width of the outer peripheral port 1252 of the preheating channel 125 is greater than the width of the inner peripheral port 1251 of the preheating channel 125. The preheating channel 125 is formed with a large inlet and a small outlet, which is conducive to the gas on the outer peripheral side of the energy-concentrating ring 120 being introduced into the inner peripheral side of the energy-concentrating ring 120 through the preheating channel 125.

[0051] See Figure 5 This further illustrates the energy-concentrating effect of the pot support 100.

[0052] exist Figure 5 In the diagram, red arrows represent high-temperature flue gas, blue arrows represent cold air, and yellow arrows represent a mixture of cold air and high-temperature flue gas. High-temperature flue gas from the inner circumference of the energy-concentrating ring 120 of the boiler support 100 rises along the upper surface of the energy-concentrating ring 120, i.e., the upper surface of the upper shell 121. Due to the wall adhesion effect, the high-temperature flue gas flows along the upper surface of the upper shell 121 to the outer circumference of the energy-concentrating ring 120. At the outer circumference of the energy-concentrating ring 120, it enters the preheating channel 125 through the outer circumferential port 1252. Simultaneously, because the air on the inner circumference of the energy-concentrating ring 120 is consumed by the burner on the inner circumference of the energy-concentrating ring 120, a negative pressure is formed on the inner circumference of the energy-concentrating ring 120, causing a mixture of cold air and high-temperature flue gas to form in the preheating channel 125. The outer periphery draws air towards the inner periphery. Therefore, the high-temperature flue gas flowing along the upper surface of the upper shell 121 to the outer periphery of the energy-concentrating ring 120 is drawn into the preheating channel 125. At the same time, cold air is also drawn from the outer periphery of the energy-concentrating ring 120 into the preheating channel 125. Thus, the mixed gas formed by the high-temperature flue gas and cold air is supplied to the inner periphery of the energy-concentrating ring 120 along the preheating channel 125. Meanwhile, the heat insulation cavity 127 of the preheating channel 125 has a preheating and heat insulation effect, preventing the mixed gas in the preheating channel 125 from directly contacting the cold air at the bottom of the energy-concentrating ring 120.

[0053] Meanwhile, the preheating channel 125 is positioned above the insulation cavity 127 instead of below it, further improving the preheating effect. Positioning the preheating channel 125 above, closer to the flame, results in a higher preheating temperature. Additionally, the hot air in the insulation cavity 127 below the preheating channel 125 will also be closer to the top (high-temperature air rises), further contributing to a higher preheating temperature.

[0054] This embodiment also provides a cooktop, which includes the pot support 100 as described above.
