A pot rack and gas stove

Abstract

This invention relates to the field of gas appliance technology, and more particularly to a pot rack and a gas stove. The pot rack includes an upper plate and a lower plate, which together form a first cavity. The inner and outer ring ends of the first cavity are respectively provided with a first channel and a second channel communicating with the outside. By providing the first cavity, heat transfer and loss from the upper part of the pot rack to the lower part is reduced, improving the heat retention effect of the pot rack and preventing the temperature of the placement panel below the pot rack from becoming too high, which would lead to a poor user experience. The first and second channels ensure that the first cavity is connected to the outside, extending the service life of the pot rack and reducing the impact on secondary air supply.

Description

Technical Field

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

[0002] Gas stoves are essential kitchen cooking appliances in daily life. A gas stove typically includes a burner and a pot rack for placing cookware. To improve the thermal efficiency of gas stove combustion, traditional pot racks are usually equipped with an energy-concentrating plate. During use, the energy-concentrating plate can separate the secondary air required for combustion from the high-temperature flue gas, so that the high-temperature flue gas is concentrated in the energy-concentrating plate, enhancing the heat exchange between the high-temperature flue gas and the bottom of the pot.

[0003] However, in the existing pot rack, the heat above the energy-concentrating plate tends to transfer downwards during use, resulting in rapid heat loss. This also causes the placement panel below the gas stove to get quite hot, affecting the user's operation and reducing the user's comfort. Summary of the Invention

[0004] The first objective of this invention is to provide a pot rack with good heat preservation and insulation effects, so as to alleviate the technical problems in the prior art where heat above the energy-concentrating plate is easily transferred downwards, resulting in rapid heat loss and high temperature of the placement panel below the gas stove.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pot rack for mounting on the periphery of a burner includes an upper plate and a lower plate, which together form a first cavity. The inner and outer ring ends of the first cavity are respectively provided with a first channel and a second channel communicating with the outside.

[0007] Furthermore, the inner ring end of the upper plate and the inner ring end of the lower plate form the first channel;

[0008] The outer ring ends of the upper plate and the outer ring ends of the lower plate form the second channel.

[0009] Furthermore, the upper plate body includes an upper plate and a lower plate, the edges of the upper plate and the lower plate are connected, and a sealed second cavity is formed between the upper plate and the lower plate.

[0010] Furthermore, the end of the first cavity that connects to the second channel has a constricted structure.

[0011] Furthermore, the first cavity includes a first cavity and a second cavity that are connected. The first cavity is connected to the second channel, and the second cavity is connected to the first channel. The end of the first cavity connected to the second channel has a constricted structure.

[0012] Furthermore, the cross-sectional area of ​​the first cavity gradually increases from the end connected to the second channel to the opposite end; and / or,

[0013] The cross-sectional area of ​​the second cavity is the same everywhere from the end connected to the first cavity to the end connected to the first channel.

[0014] Furthermore, the lower plate body includes an inclined wall, a vertical wall, a straight wall, and an arc-shaped wall that are connected sequentially from the inner ring end to the outer ring end of the lower plate body;

[0015] The inclined wall and the upper plate form the first channel; the vertical wall, the straight wall, and the upper plate form the second cavity; the arc-shaped wall and the upper plate form the first cavity and the second channel.

[0016] Furthermore, the pot rack is used to place a pot on top, and there is an exhaust port between the pot rack and the pot for gas to escape;

[0017] The second channel is positioned so that the end furthest from the first cavity faces the exhaust port.

[0018] Furthermore, the cross-sectional area of ​​the second channel gradually increases from the end connected to the first cavity to the end connected to the outside.

[0019] Furthermore, the outer periphery of the upper plate is provided with a baffle, and the baffle is located above the end of the second channel away from the first cavity.

[0020] Furthermore, the cross-sectional area of ​​the first channel is smaller than the longitudinal area of ​​the connection end between the first cavity and the second channel.

[0021] Furthermore, a number of support blocks are provided between the upper plate and the lower plate;

[0022] The upper and lower ends of the support block abut against the lower end face of the upper plate and the upper end face of the lower plate, respectively.

[0023] Furthermore, the inner ring end of the upper plate is provided with a first inclined surface, and the outer periphery of the burner is provided with a second inclined surface, and an air intake channel is formed between the first inclined surface and the second inclined surface;

[0024] The first inclined plane and the second inclined plane are arranged in parallel, and the first inclined plane and the second inclined plane are inclined upward in a direction closer to the center of the burner.

[0025] Furthermore, the inner ring end of the lower plate is provided with an inclined wall, and the inclined wall and the upper plate form the first channel;

[0026] The inclined wall is arranged parallel to the first inclined plane and the second inclined plane.

[0027] The second objective of this invention is to provide a gas stove that alleviates the technical problems existing in the prior art, such as the heat above the energy-concentrating plate easily transferring downwards, resulting in rapid heat loss and high temperature of the placement panel below the gas stove.

[0028] To achieve the above objectives, the present invention adopts the following technical solution:

[0029] A gas stove, including the pot rack as described above.

[0030] Furthermore, the gas stove also includes a burner and a water collection tray disposed below the burner and the pot rack;

[0031] A fixed support foot is provided below the lower plate body, and the lower end of the fixed support foot is inserted into the mounting groove on the water receiving plate.

[0032] The beneficial effects of this invention are:

[0033] This invention provides a pot rack and a gas stove. The pot rack is used to be installed around the burner. The pot rack includes an upper plate and a lower plate, which together form a first cavity. The inner and outer ring ends of the first cavity are respectively provided with a first channel and a second channel communicating with the outside.

[0034] This embodiment forms a heat insulation barrier by setting a first cavity, which reduces the heat transfer and loss from the upper part of the pot rack to the lower part. On the one hand, it can reduce heat loss and improve the heat preservation effect of the pot rack, so that the combustion is more complete. On the other hand, it can also improve the heat insulation effect of the pot rack, so as to avoid the temperature of the placement panel below the pot rack being too high, resulting in a poor user experience.

[0035] By setting up a first channel and a second channel, on the one hand, the first cavity is connected to the outside, which improves the service life of the pot rack. After the pot rack is used, the first cavity can quickly exchange heat with the outside, improving the cooling effect. On the other hand, during the use of the pot rack, most of the hot air is discharged from the top of the pot rack, but a small amount of hot air still diffuses downward from the gap between the pot rack and the gas stove (i.e., the air intake channel), which affects the secondary air supply. In this embodiment, the downward diffused hot air can be discharged along the first channel, the first cavity, and the second channel, mitigating the impact of the downward diffusion of hot air on the secondary air supply.

[0054] Example 1

[0055] Reference Figure 1 This invention provides a pot frame for placement around a burner 1, comprising an upper plate 21 and a lower plate 22, which together form a first cavity 23. The inner and outer ring ends of the first cavity 23 are respectively provided with a first channel 24 and a second channel 25 communicating with the outside.

[0056] In this embodiment, by setting the first cavity 23, a heat insulation barrier is formed, which reduces the heat transfer and loss from the upper part of the pot rack to the lower part. On the one hand, it can reduce heat loss and improve the heat preservation effect of the pot rack, so that the combustion is more complete; on the other hand, it can also improve the heat insulation effect of the pot rack, so as to avoid the temperature of the placement panel 7 under the pot rack being too high, resulting in a poor user experience.

[0057] The gap between the pot frame and the burner 1 forms an air intake channel 5 for secondary air supply. In this embodiment, by setting the first channel 24 and the second channel 25, on the one hand, the first cavity 23 is in a state of communication with the outside, which improves the service life of the pot frame, and after the pot frame is used, the first cavity 23 can exchange heat with the outside, improving the cooling effect; on the other hand, during the use of the pot frame, most of the hot air is discharged from the top of the pot frame, but a small amount of hot air still diffuses downward from the gap between the pot frame and the burner 1 (i.e., the air intake channel 5), thus affecting the secondary air supply. In this embodiment, the downward diffused hot air can be discharged along the first channel 24, the first cavity 23 and the second channel 25, mitigating the impact of the downward diffusion of hot air on the secondary air supply.

[0058] In this embodiment, the inner ring end of the upper plate 21 and the inner ring end of the lower plate 22 form a first channel 24, and the outer ring end of the upper plate 21 and the outer ring end of the lower plate 22 form a second channel 25. There is no need to process the first channel 24 and the second channel 25 separately, which reduces production costs.

[0059] Furthermore, a plurality of support blocks 27 are provided between the upper plate 21 and the lower plate 22, with the upper and lower ends of the support blocks 27 respectively abutting against the lower end face of the upper plate 21 and the upper end face of the lower plate 22. The support blocks 27 separate the upper plate 21 and the lower plate 22, forming a first cavity 23. Optionally, the support blocks 27 can be fixed to the upper plate 21 or the lower plate 22. The provision of support blocks 27 reduces the contact area between the upper plate 21 and the lower plate 22, thereby reducing heat transfer.

[0060] Reference Figure 1 and Figure 2 The upper plate 21 includes an upper plate 211 and a lower plate 212. The edges of the upper plate 211 and the lower plate 212 are connected, and a sealed second cavity 26 is formed between the upper plate 211 and the lower plate 212. In this embodiment, by setting the second cavity 26, a second heat insulation barrier is formed, which further reduces heat loss and improves energy efficiency.

[0061] Reference Figure 3 and Figure 4 The end where the first cavity 23 connects to the second channel 25 has a constricted structure. Specifically, the position where the first cavity 23 connects to the second channel 25 forms a constriction 233. The constricted structure can prevent hot air inside the first cavity 23 from flowing out of the second channel 25, and at the same time, it can also prevent outside air from entering the first cavity 23, reducing heat loss caused by air convection and achieving the purpose of improving energy efficiency.

[0062] In this embodiment, the first cavity 23 includes a first cavity 231 and a second cavity 232 that are connected. The first cavity 231 is connected to the second channel 25, and the second cavity 232 is connected to the first channel 24. The end of the first cavity 231 connected to the second channel 25 is a constricted structure, and the position where the first cavity 231 and the second channel 25 are connected forms a constriction 233.

[0063] Figure 4 The image shows a structural diagram of the cross-section of the first cavity 231. (Refer to...) Figure 4 The cross-sectional area of ​​the longitudinal section of the first cavity 231 gradually increases from the end connected to the second channel 25 to the opposite end; and / or, the cross-sectional area of ​​the longitudinal section of the second cavity 232 is equal everywhere from the end connected to the first cavity 231 to the end connected to the first channel 24.

[0064] Furthermore, the pot rack is used to place the pot 3 above it, and there is an exhaust port 4 between the pot rack and the pot 3 for gas to escape. The end of the second channel 25 away from the first cavity 23 is set towards the exhaust port 4. During use, the high-temperature exhaust gas generated between the pot 3 and the pot rack is discharged from the exhaust port 4, making the temperature at the outlet of the second channel 25 relatively high. Moreover, due to the obstruction of exhaust gas discharge, the hot air in the first cavity 23 is not easily lost due to air convection, further reducing the heat loss in the first cavity 23. After use, since the exhaust port 4 no longer emits exhaust gas, the hot air in the first cavity 23 can exchange heat with the outside environment to cool down quickly.

[0065] Based on the above structure, the cross-sectional area of ​​the second channel 25 gradually increases from the end connected to the first cavity 23 to the end connected to the outside, that is, a flared structure is formed at the end near the exhaust port 4. The purpose is to reduce the air pressure at the outlet of the second channel 25, weaken the generation of the wind wall, reduce the interference to the exhaust of the exhaust port 4, and ensure that CO in the exhaust gas can be discharged normally.

[0066] Optionally, a baffle 213 is provided on the outer periphery of the upper plate 21, and the baffle 213 is located above the end of the second channel 25 away from the first cavity 23. The purpose of providing the baffle 213 is to further reduce the interference of the exhaust of the second channel 25 on the exhaust of the exhaust port 4.

[0067] Furthermore, the cross-sectional area of ​​the first channel 24 is smaller than the longitudinal area of ​​the connection end between the first cavity 23 and the second channel 25. In this embodiment, the first channel 24 adopts a slender slit structure, and its cross-sectional area is much smaller than the longitudinal area of ​​the constriction 233, thereby blocking the hot air in the first cavity 23 from being discharged from the first channel 24 as much as possible, which has the effect of improving energy efficiency; at the same time, it avoids interfering with the secondary air supply and affecting the stability of combustion.

[0068] Optionally, one end of the first channel 24 is connected to the first cavity 23, and the other end faces the burner 1 and is inclined upward. This arrangement makes it difficult for air from the air intake channel 5 to enter the first channel 24, further improving the effect of secondary air supply and reducing heat loss caused by air convection in the first cavity 23.

[0069] In this embodiment, the second cavity 26 mainly serves to improve energy efficiency, while the first cavity 23 mainly serves to reduce the downward transfer of heat and reduce heat loss. By setting the sealed second cavity 26, heat is concentrated in the upper part of the upper plate 21, thereby improving the thermal efficiency of combustion. By setting the first cavity 23 below the second cavity 26 and communicating with the outside, the second cavity 26 and the placement panel 7 are separated, preventing heat from being transferred downward and causing heat loss and excessive temperature of the placement panel 7. Furthermore, the hot air in the first cavity 23 has a heat preservation effect on the second cavity 26.

[0070] Reference Figure 4 In this embodiment, when the pot rack is in use, outside air enters the upper part of the pot rack through the air intake channel 5 to provide timely secondary air supply. Most of the exhaust gas between the pot 3 and the pot rack support is discharged from the exhaust port 4, and a small portion diffuses downward along the gap between the pot rack and the burner 1 (i.e., the air intake channel 5), and is discharged sequentially from the first channel 24, the first cavity 23, and the second channel 25, mitigating the impact of the downwardly diffused hot air on the secondary air supply. Both outlets of the first cavity 23 adopt a constricted structure, thereby reducing the outflow of hot air in the first cavity 23, reducing heat loss caused by air convection, and achieving the purpose of improving energy efficiency. The outlet of the second channel 25 faces the exhaust port 4, and the high-temperature exhaust gas discharged from the exhaust port 4 can block the convection between the outside room temperature air and the hot air in the first cavity 23, thus preventing heat loss. The outlet of the second channel 25 adopts a flared structure, which can reduce the air pressure at the outlet of the second channel 25, thereby reducing interference with the exhaust of the exhaust port 4.

[0071] Reference Figure 5 The lower plate 22 includes an inclined wall 221, a vertical wall 222, a straight wall 223, and an arc-shaped wall 224 connected sequentially from the inner ring end to the outer ring end of the lower plate 22; the inclined wall 221 and the upper plate 21 form a first channel 24; the vertical wall 222, the straight wall 223, and the upper plate 21 form a second cavity 232; the arc-shaped wall 224 and the upper plate 21 form a first cavity 231 and a second channel 25.

[0072] In this embodiment, the support block 27 is disposed at the flat wall 223 to improve the stability of the connection between the upper plate 21 and the lower plate 22.

[0073] Reference Figure 6The upper plate 21 has a first inclined surface 214 at its inner ring end, and a second inclined surface 11 is provided on the outer periphery of the burner 1. An air intake channel 5 is formed between the first inclined surface 214 and the second inclined surface 11. The first inclined surface 214 and the second inclined surface 11 are arranged in parallel and are inclined upward towards the center of the burner 1. Because the first inclined surface 214 and the second inclined surface 11 are arranged in parallel, the air intake channel 5 has no dead corners, which facilitates the flow of air and ensures the supply of secondary air, thereby improving combustion efficiency. In addition, in the prior art, the inner ring surface of the energy-concentrating plate and the outer wall of the burner usually form an annular inlet for air to flow in. This straight-up and down annular inlet structure makes it easy for the high-temperature flue gas above the energy-concentrating plate to flow downward from the annular inlet, resulting in heat loss. However, in this application, the air intake channel 5 is inclined upward towards the center of the burner 1, which makes it difficult for the high-temperature flue gas above the upper plate 21 to flow downward from the air intake channel 5, thereby improving energy efficiency.

[0074] Furthermore, an inclined wall 221 is provided at the inner ring end of the lower plate 22, and the inclined wall 221 and the upper plate 21 form a first channel 24; the inclined wall 221 is arranged parallel to the first inclined surface 214 and the second inclined surface 11 to facilitate the flow of air.
