[0002] Gas stoves are common kitchen appliances used in daily family cooking. With the continuous development of society, high combustion thermal efficiency has become one of the development directions of gas stoves. In order to pursue higher thermal efficiency, some manufacturers have developed gas stoves with energy-gathering disk pot stands. Among them, the structural patterns of the energy-gathering disk pot stands include single-layer, double-layer and multi-layer, so that the high-temperature flue gas generated by combustion is gathered in the energy-gathering disk, enhancing the heat exchange intensity between the high-temperature flue gas and the bottom of the pot, thereby improving the combustion thermal efficiency.

[0003] However, due to the unreasonable structural setting of the existing energy-gathering disk pot stand, the flow rate of the high-temperature flue gas generated by combustion in the energy-gathering disk is relatively too large, which is not conducive to the gathering of combustion heat energy, resulting in insufficient impact strength of the high-temperature flue gas on the bottom of the pot, poor heat exchange effect with the bottom of the pot, and low utilization rate of combustion heat energy, thus resulting in the problem of low overall combustion thermal efficiency.

[0004] Therefore, it is urgent to design an energy-gathering disk pot stand and a gas stove to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an energy-gathering disk pot stand, which can enhance the heat exchange effect between the high-temperature flue gas and the bottom of the pot and improve the combustion thermal efficiency.

[0007] An energy-gathering disk pot stand, comprising:

[0008] An energy-gathering disk body, which is a concave annular disk body, and is provided with an avoidance through hole for avoiding a burner;

[0009] A bracket for supporting a pot, the bracket is arranged on the energy-gathering disk body, and an L-shaped high-temperature flue gas diversion channel is jointly formed between the bottom of the bracket and the inner side wall of the energy-gathering disk body and between the outer side wall of the bracket and the inner side wall of the energy-gathering disk body.

[0010] As a preferred technical solution of the above-mentioned energy-gathering disk pot stand, the energy-gathering disk body includes a chassis part, a support part and a surrounding part which are connected in sequence along the radial direction. The avoidance through-hole is arranged at the center of the chassis part. The surrounding part is arranged in the vertical direction. The bracket is arranged on the support part and inside the surrounding part. There is a first gap between the bracket and the support part, and a second gap between the bracket and the surrounding part. The first gap and the second gap communicate with each other and jointly form the high-temperature flue gas diversion channel.

[0011] As a preferred technical solution of the above-mentioned energy-gathering disk pot stand, the bracket includes a bottom ring and a plurality of support members. The plurality of support members are arranged on the bottom ring along the circumferential direction. The support members are in contact with the bottom of the cookware for supporting the cookware. The bottom ring is spaced from the support part to form the first gap, and the bottom ring is spaced from the surrounding part to form the second gap.

[0012] As a preferred technical solution of the above-mentioned energy-gathering disk pot stand, the lower end surface of the support member is lower than the lower surface of the bottom ring. The outer diameter of the support member is larger than the outer diameter of the bottom ring and not larger than the inner diameter of the surrounding part.

[0013] As a preferred technical solution of the above-mentioned energy-gathering disk pot stand, the outer diameter of the support member is smaller than the inner diameter of the surrounding part.

[0019] To achieve this purpose, the present utility model also adopts the following technical solutions:

[0020] A gas stove includes the above-mentioned energy-gathering disk pot stand.

[0021] The energy - gathering disk pot stand disclosed by the utility model includes an energy - gathering disk body and a bracket. The energy - gathering disk body is a concave annular disk body, and an avoidance through - hole is formed thereon. The avoidance through - hole is used to avoid the burner. The bracket is used to support the cookware. The bracket is arranged on the energy - gathering disk body. An L - shaped high - temperature flue gas diversion channel is jointly formed between the bottom of the bracket and the inner side wall of the energy - gathering disk body and between the outer side wall of the bracket and the inner side wall of the energy - gathering disk body.

[0037] This embodiment provides a heat - concentrating disk pot rack, which has a flow - guiding structure, prolongs the residence time of the high - temperature combustion flue gas in the heat - concentrating disk pot rack, and thus improves the combustion thermal efficiency of the gas stove.

[0038] As Figure 1 and Figure 2 shown, the heat - concentrating disk pot rack includes a heat - concentrating disk body 1 and a bracket 2. Among them, an avoidance through - hole 11 is formed on the heat - concentrating disk body 1. The avoidance through - hole 11 is used to avoid the burner 100, so that the heat - concentrating disk body 1 is sleeved on the outer periphery of the burner 100. The inner diameter of the avoidance through - hole 11 is larger than the outer diameter of the burner 100, ensuring sufficient assembly clearance and also ensuring the entry and supply of the required secondary air during combustion, making the combustion more complete and improving the overall combustion effect.

[0039] The heat - concentrating disk body 1 is a concave annular disk, and its outer edge is relatively higher than the inner edge. This structural setting is conducive to the gathering of the high - temperature combustion flue gas, strengthening the heat - exchange intensity with the bottom of the pot, reducing the loss of heat radiation of the high - temperature combustion flue gas to the surrounding, effectively improving the thermal energy utilization rate, and thus improving the combustion thermal efficiency.

[0040] The bracket 2 is disposed on the heat - concentrating disk body 1, and the bracket 2 is used to support the cookware. A high - temperature flue gas flow - guiding channel in an L - shape is jointly formed between the bottom of the bracket 2 and the inner side wall of the heat - concentrating disk body 1 and between the outer side wall of the bracket 2 and the inner side wall of the heat - concentrating disk body 1.

[0041] The L-shaped high-temperature flue gas diversion channel can conduct layered diversion of the combustion high-temperature flue gas in the energy-gathering disc body 1. A part of the high-temperature flue gas flows from the upper end of the bracket 2, and another part of the high-temperature flue gas flows from the lower end of the bracket 2 and flows from horizontal to vertically upward along the L-shaped high-temperature flue gas diversion channel, while impacting the high-temperature flue gas flowing at the upper end of the bracket 2, disturbing it to form a turbulent flow, thereby delaying the flow rate of the high-temperature flue gas in the energy-gathering disc pot rack, extending the heat exchange time between the high-temperature flue gas and the bottom of the pot, being conducive to the gathering of combustion heat energy, and at the same time playing a role in diverting upward to the bottom of the pot, increasing the impact intensity of the high-temperature flue gas on the bottom of the pot, enhancing the heat exchange effect with the bottom of the pot, thereby improving the utilization rate of combustion heat energy and the combustion thermal efficiency of the gas stove.

[0042] Combined Figure 3 As shown, the energy-gathering disc body 1 includes a chassis part 10, a support part 12, and a surrounding part 13 that are sequentially connected along the radial direction. The above-mentioned avoidance through-hole 11 is provided at the center of the chassis part 10. The surrounding part 13 is arranged in the vertical direction. The bracket 2 is arranged on the support part 12 and is located inside the surrounding part 13. The support part 12 and the surrounding part 13 are used to place and radially limit the bracket 2. There is a first gap between the bracket 2 and the support part 12, and a second gap between the bracket 2 and the surrounding part 13. The first gap and the second gap are connected and jointly form the above-mentioned L-shaped high-temperature flue gas diversion channel. The support part 12 can be, but is not limited to, an annular step structure, and the surrounding part 13 can be, but is not limited to, a vertically arranged surrounding ring structure.

[0043] Specifically, the bracket 2 includes a bottom ring 21 and a plurality of support members 22. The bottom ring 21 is annular as a whole. The plurality of support members 22 are arranged on the bottom ring 21 along the circumferential direction. The support members 22 are in contact with the bottom of the cookware for supporting the cookware. The cookware is placed on the plurality of support members 22, which is stable and reliable. The bottom ring 21 is spaced from the support part 12 to form a first gap, and the bottom ring 21 is spaced from the surrounding part 13 to form a second gap. The existence of the first gap and the second gap makes the bottom ring 21 not in direct contact with the support part 12 and the surrounding part 13, reducing the heat conduction loss.

[0044] The above structural arrangement enables the support 2 to divide the high-temperature combustion flue gas in the energy-gathering disc body 1 into upper and lower parts for diversion. That is to say, when the high-temperature flue gas generated during the combustion of the burner 100 flows in the energy-gathering disc body 1, the bottom ring 21 conducts stratified diversion on it. One part flows from the upper end of the bottom ring 21, and the other part flows from the lower end of the bottom ring 21. The high-temperature flue gas flowing from the lower end of the bottom ring 21 flows from horizontal to vertically upward along the L-shaped high-temperature flue gas diversion channel, and at the same time impacts the high-temperature flue gas flowing at the upper end of the bottom ring 21, generating turbulence on it, thereby retarding and delaying the flow velocity of the high-temperature flue gas at the upper end of the bottom ring 21, prolonging the residence time of the high-temperature combustion flue gas in the energy-gathering disc body 1, that is, prolonging the heat exchange time between the high-temperature flue gas and the bottom of the pot. At the same time, it also plays a role in diverting upward to the bottom of the pot, increasing the impact intensity of the high-temperature combustion flue gas on the bottom of the pot, greatly enhancing the heat exchange effect between the high-temperature combustion flue gas and the bottom of the pot, and also contributing to the re-combustion of the high-temperature flue gas, making the combustion more complete, thereby improving the combustion thermal efficiency of the gas stove.

[0045] To achieve the above structure, the upper end face of the support member 22 is higher than the upper surface of the bottom ring 21, the lower end face of the support member 22 is lower than the lower surface of the bottom ring 21, and the outer diameter of the support member 22 is greater than the outer diameter of the bottom ring 21 and not greater than the inner diameter of the enclosure portion 13. This structure enables the bottom ring 21 not to be in direct contact with the support portion 12 or the enclosure portion 13, greatly reducing the contact area between the support 2 and the energy-gathering disc body 1, thereby reducing the heat conduction loss.

[0046] In this embodiment, the outer diameter of the support member 22 is smaller than the inner diameter of the enclosure portion 13. Under this structure, there is an appropriate assembly gap between the support 2 and the inner side wall of the enclosure portion 13, which plays a role in facilitating the taking and placing of the support 2 and radial positioning. Such a structural arrangement not only ensures the relatively stable placement of the support 2 but also avoids the direct contact between the support 2 and the outside air, reducing the outward overflow of heat energy, enabling more of the combustion heat energy absorbed by the support 2 to be conducted to the bottom of the pot, reducing the heat energy loss, and improving the heat energy utilization rate.

[0047] The upper end face of the support member 22 is higher than the upper end face of the enclosure portion 13. This structure can ensure the reasonable discharge of flue gas, achieve the balance of the combustion condition, and improve the overall combustion effect.

[0048] In order to make the diversion of the high-temperature combustion flue gas, namely the L-shaped high-temperature flue gas diversion channel, more effective, to enhance the turbulence and impact intensity formed by the high-temperature combustion flue gas at the bottom of the pot, and at the same time delay the flow rate of the high-temperature flue gas, that is, extend the residence time of the high-temperature flue gas at the bottom of the pot, further strengthen the heat exchange effect between the high-temperature combustion flue gas and the bottom of the pot, improve the thermal energy utilization rate, and also to contribute to the re-combustion of the high-temperature flue gas to make the combustion more complete, thereby improving the combustion thermal efficiency. In this embodiment, the radial width of the bottom ring 21 ranges from 8 mm to 17 mm. For example, it can be 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm or 17 mm, and it can be selected according to the actual situation.

[0049] The value range of the first gap between the bottom ring 21 and the support part 12 is 5 mm to 8 mm. For example, it can be 5 mm, 6 mm, 7 mm or 8 mm, and it can be selected according to the actual situation.

[0050] The value range of the second gap between the bottom ring 21 and the enclosure part 13 is 3 mm to 4.5 mm. For example, it can be 3 mm, 3.5 mm, 4 mm or 4.5 mm, and it can be selected according to the actual situation.

[0051] In addition, the upper end face of the bottom ring 21 is flush with or slightly lower than the upper end of the enclosure part 13, and the value range of the height difference is 0 mm to 2 mm. For example, it can be 0 mm, 1 mm or 2 mm. Such a setting can play a certain role in blocking and diverting the high-temperature combustion flue gas and delay the flow rate of the high-temperature flue gas. The inner diameter of the bottom ring 21 is smaller than the inner diameter of the support part 12. Ensure the relatively stable placement of the bracket 2, reduce the contact area between the bottom ring 21 and the support part 12, and reduce the heat conduction loss.

[0052] In this embodiment, there are at least three support members 22. The support members 22 and the bottom ring 21 are of welded combination structure. Of course, they can also be of integral casting structure. At least three support members 22 are evenly arranged at equal intervals in the circumferential direction for supporting the cooking pot.

[0053] The energy-gathering disk pot stand can be arranged in a single-layer, double-layer or multi-layer structure above double-layer. The energy-gathering disk pot stand in this embodiment is a double-layer structure, that is, the energy-gathering disk pot stand further includes a bottom cover shell connected to the energy-gathering disk body 1, and a heat insulation and heat preservation cavity 200 is formed between the bottom cover shell and the energy-gathering disk body 1. The bottom cover shell is integrally in a ring-shaped deep concave disk shape, and a through hole is opened in the middle thereof. The inner diameter of the through hole is larger than the outer diameter of the burner 100, and the outer edge end of the bottom cover shell is higher than the inner hole edge end. The energy-gathering disk body 1 is located above the bottom cover shell. The inner hole edge of the energy-gathering disk body 1 is attached to the inner hole edge of the bottom cover shell, and the outer edge of the energy-gathering disk body 1 is also attached to the outer edge of the bottom cover shell. The above-mentioned attachment parts can adopt a welding process, and the rest are all arranged in an air-insulated manner. In this way, a heat insulation and heat preservation cavity 200 is formed between the bottom cover shell and the energy-gathering disk body 1. There is air in the heat insulation and heat preservation cavity 200. By using the characteristic that the heat conduction performance of air is poor, the heat insulation and heat preservation cavity 200 can play a very good heat insulation and heat preservation effect, reduce heat loss and improve the utilization rate of heat energy. The energy-gathering disk body 1 is close to the combustion flame, and its temperature rises faster, realizing that the heat energy of the high-temperature combustion flue gas gathered in the energy-gathering disk body 1 is higher, thereby enhancing the heat exchange effect between the high-temperature combustion flue gas and the bottom of the pot and improving the combustion heat efficiency.

[0054] The energy-gathering disk pot stand in this embodiment is circular, and can also be square, square-round, oval, polygon, etc., and can be specifically set according to actual situations.

[0055] The energy-gathering disk body 1 and the bracket 2 in this embodiment are set in a detachable connection form, which is convenient for cleaning. At the same time, the generalization and scale of the energy-gathering disk body 1 can be realized, and the production efficiency can be improved to reduce costs. The bracket 2 can be set in a variety of styles to meet the needs of different consumers.

[0056] At least three feet 3 are provided on the bottom surface of the energy-gathering disk body 1. By providing the feet 3, a secondary air inlet channel is formed between the bottom surface of the energy-gathering disk body 1 and the cooker panel, so as to ensure the supply of secondary air required for combustion to achieve more complete combustion.

[0057] In order to reduce the occurrence of adverse phenomena such as heat loss and abrasion caused by the direct contact between the feet 3 and the cooker panel or the liquid receiving tray, optionally, a non-metallic pad is provided at the bottom of the feet 3. The non-metallic pad can be made of temperature-resistant silicone rubber, fluororubber, polytetrafluoroethylene and other materials, which can play a role in reducing heat conduction loss and buffering, and at the same time avoid the occurrence of adverse phenomena of abrasion.

[0058] The energy-gathering disc pot stand provided by this embodiment realizes the effective gathering of high-temperature combustion flue gas, reduces the loss of heat radiation from the high-temperature combustion flue gas to the surroundings, and improves the utilization rate of combustion heat energy. On the one hand, it effectively delays the flow rate of the high-temperature flue gas, prolongs the residence time of the high-temperature flue gas at the bottom of the pot, that is, extends the heat energy exchange time between the high-temperature flue gas and the bottom of the pot, and enhances the heat exchange intensity between the high-temperature flue gas and the bottom of the pot; on the other hand, it realizes the enhancement of the turbulence and impact intensity formed by the high-temperature combustion flue gas at the bottom of the pot, further strengthens the heat exchange effect between the high-temperature combustion flue gas and the bottom of the pot, thereby improving the combustion thermal efficiency; on the other hand, it also helps the re-combustion of the high-temperature flue gas, makes the combustion more complete, and reduces the generation of waste gases such as CO.

[0059] This embodiment also provides a gas stove, which includes the aforementioned energy-gathering disc pot stand. Since this gas stove includes the aforementioned energy-gathering disc pot stand, thus, the technical advantages and effects that this gas stove can achieve also include the technical advantages and effects that the energy-gathering disc pot stand can achieve, which will not be elaborated here.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments here, and various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments only. Without departing from the concept of the present invention, it can also include more other equivalent embodiments, and the scope of the present invention is determined by the scope of the appended claims.
