Description

Technical Field

[0002] Gas stoves are a staple of everyday household cooking. With the continuous development of society, high combustion thermal efficiency has become a key development trend for gas stoves. To achieve even higher thermal efficiency, some manufacturers have developed gas stoves with energy-concentrating pan supports. These pan supports come in single-layer, double-layer, and multi-layer configurations. These pan supports separate the secondary air required for combustion from the high-temperature flue gases generated by combustion, trapping them within the pan. This enhances heat exchange between the flue gases and the pan bottom, reduces radiative and convective heat loss, and effectively concentrates heat energy, improving combustion efficiency.

[0003] However, the existing energy-gathering pan rack has the following main problems: since its structural design focuses too much on the gathering of high-temperature flue gas, and does not fully utilize the combustion heat energy to preheat the secondary air required for combustion, the utilization rate of the combustion heat energy is not high, resulting in low overall combustion thermal efficiency.

[0004] Therefore, it is urgent to design a kind of energy-gathering plate pot rack and gas cooker to solve the above-mentioned technical problems. Utility Model Content

[0037] Example 1

[0038] This embodiment provides a gas cooker, which includes a burner 100 and an energy-gathering pan support. The energy-gathering pan support is arranged around the outer circumference of the burner 100 and can support the cookware above the burner 100.

[0039] like Figure 1 and Figure 2As shown, the energy-gathering pan stand comprises an energy-gathering pan stand body and a support member 3. The energy-gathering pan body has a central through-hole, which is used to accommodate the burner 100. The upper end of the burner 100 is located within the central through-hole. The support member 3 is positioned on the upper surface of the energy-gathering pan body to support the pot. The highest point of the support member 3 is higher than the highest point of the upper surface of the energy-gathering pan body. When the pot is placed on the support member 3, an air passage and an exhaust channel are formed between the bottom of the pot and the upper surface of the energy-gathering pan body. The air passage allows high-temperature flue gas to flow, effectively exchanging heat with the bottom of the pot. The exhaust channel allows the high-temperature flue gas to be discharged, ensuring a negative pressure in the inner area of ​​the energy-gathering pan body and the area between the energy-gathering pan body and the burner 100, thereby ensuring a continuous supply of secondary air to the flame hole of the burner 100. Multiple support members 3 are provided to collectively support the pot. The multiple support members 3 are evenly spaced along the circumference of the energy-gathering pan body to ensure stable pot placement. In this embodiment, the number of the supporting members 3 is four, thereby ensuring stable support for the cookware. In other embodiments, the number of the supporting members 3 may also be three, five or more, which is not specifically limited here.

[0040] like Figure 1 and Figure 2 As shown, the inner diameter of the central through-hole is larger than the outer diameter of the burner 100. This ensures sufficient assembly clearance and allows for a secondary air inlet to form between the energy concentrating disc body and the burner 100 when assembled, ensuring more complete combustion and improving overall combustion performance. A secondary air preheating cavity 200 is formed within the energy concentrating disc body, surrounding the central through-hole. The secondary air preheating cavity 200 communicates with the secondary air inlet. A secondary air inlet 21 is provided on the energy concentrating disc body, communicating with the secondary air preheating cavity 200 and connecting the secondary air inlet 21 to the external environment. The upper surface of the energy concentrating disc body is made of glass with a melting point higher than the combustion temperature of the gas cooker. The secondary air preheating cavity 200 communicates with the external environment through the secondary air inlet 21, allowing air from the external environment to enter the burner 100 through the secondary air preheating cavity 200 and participate in combustion. Secondary air enters the secondary air preheating chamber 200 through the secondary air inlet. After being preheated, the secondary air is promptly supplied to the periphery of the burner 100 through the secondary air supply inlet. The fully preheated secondary air participates in the combustion, which can effectively enhance the temperature field of the high-temperature flue gas, strengthen the heat exchange effect with the bottom of the pot, and improve the thermal efficiency.

[0041] When light enters glass, it exhibits three properties: transmission, absorption, and reflection. Therefore, glass exhibits excellent light transmittance, or "transmission." Light generated by the combustion flame can transmit through the upper surface of the energy concentrating disk body, heating the air in the secondary air preheating chamber 200, which contains the secondary air required for combustion. Furthermore, because the upper surface of the energy concentrating disk body is close to the burner 100 flame, the temperature of the secondary air in the secondary air preheating chamber 200 is increased more rapidly, resulting in a higher and more complete preheating of the secondary air. This preheated secondary air participates in combustion, raising the temperature of the combustion flame and improving combustion thermal efficiency. Glass also exhibits "absorption" properties. This absorption function maintains a high temperature on the upper surface of the energy concentrating disk body and within the disk, effectively enhancing the combustion temperature field and improving combustion efficiency. In addition, the glass also has "reflective" properties, which can reflect the light generated by the burning flame to the bottom of the pot. This light can be used to heat the bottom of the pot, reduce heat energy loss, improve the utilization rate of combustion heat energy, further enhance combustion energy efficiency, and achieve an overall improvement in combustion thermal efficiency.

[0042] The glass can be transparent, translucent or colored, as long as its light transmittance reaches the set value and can withstand the combustion temperature of the gas stove.

[0043] In this embodiment, the energy concentrating disk body comprises an upper disk 1 and a lower disk 2, both of which are provided with coaxial inner holes to form the aforementioned central through hole. The upper disk 1 and the lower disk 2 enclose a secondary air preheating chamber 200. The upper disk 1 is made of glass having a melting point higher than the combustion temperature. A secondary air inlet 21 is provided on the lower disk 2. A vertical spacing is provided between the inner hole edges of the upper disk 1 and the inner hole edges of the lower disk 2 to form an open annular gap 22 circumferentially distributed along the burner 100. The open annular gap 22 serves as the aforementioned secondary air supply inlet. The open annular gap 22 connects the secondary air preheating chamber 200 with the burner 100, while the secondary air inlet 21 connects the secondary air preheating chamber 200 with the external environment. Thus, secondary air required for combustion enters the secondary air preheating chamber 200 through the secondary air inlet 21, is fully preheated, and then flows through the open annular gap 22 to the burner 100 to participate in combustion. The open annular seam 22 ensures a more even and sufficient supply of secondary air to the combustion process, achieving optimal combustion conditions. In this embodiment, the upper and lower pans 1 and 2 are designed as separate units, making them easy to disassemble and clean. Furthermore, since spills and oil droplets may drip onto the upper pan 1 during cooking, the removable glass upper pan 1 facilitates cleaning.

[0044] The upper disk 1 is a ring-shaped disk with a concave arc surface and an inner hole in the middle. The inner hole edge is low and the outer edge is high, forming an energy gathering area. This structure is conducive to the gathering of combustion heat energy air masses and can slow down the flow rate of high-temperature flue gas, thereby prolonging the heat exchange time with the bottom of the pot, and can enhance the heat exchange intensity between the combustion heat energy and the bottom of the pot, reduce the loss of combustion heat energy, improve the utilization rate of combustion heat energy, and improve the combustion thermal efficiency.

[0045] In this embodiment, a plurality of secondary air inlets 21 are provided, and the plurality of secondary air inlets 21 are evenly distributed on the outer wall of the lower disk 2 at equal intervals along the circumferential direction to ensure uniform secondary air intake.

[0046] The lower disk 2 includes an annular concave cavity, an annular inclined surface and an annular platform from the inside to the outside in the radial direction. A secondary air preheating cavity 200 is formed between the annular concave cavity and the upper disk 1. The secondary air inlet 21 is arranged on the outer wall of the annular concave cavity. The annular inclined surface is inclined upward from the inside to the outside. The outer edge bottom of the upper disk 1 is fitted with the annular inclined surface, that is, this place is in a relatively sealed state, which prevents the heat energy in the secondary air preheating cavity 200 from flowing out from this place and causing heat loss problems.

[0047] Multiple support members 3 are evenly spaced along the circumference of the energy concentrating disk body and distributed on the annular platform. To facilitate assembly and disassembly, the outer diameter of the upper disk 1 is smaller than the inner diameter of the support members 3. To enhance structural integrity and aesthetics, the outer diameter of the support members 3 is no larger than that of the annular platform. In this embodiment, the outer diameter of the support members 3 is equal to that of the annular platform, ensuring a smooth and flush outer wall.

[0048] The upper surface (i.e., inner surface) of the lower tray 2 is provided with a reflective layer for reflecting heat. The reflective layer may be, but is not limited to, a light-colored, glossy surface or a reflective coating, which reflects heat upward. This structure further enhances the heating effect on the air in the secondary air preheating chamber 200, resulting in a higher and more complete secondary air preheating temperature in the secondary air preheating chamber 200. This further improves the utilization rate of combustion heat energy, further enhances combustion energy efficiency, and thus further improves combustion thermal efficiency.

[0049] An insulation pad 23 is provided at the bottom of the lower pan 2. This pad prevents heat transfer from the energy-gathering pan support to the liquid pan or cooktop, providing insulation and a relatively sealed contact surface. This prevents heat loss from entering the pan from relatively cool air or from escaping internal heat. The insulation pad 23 can be made of a rubber material, such as silicone rubber, and can be in the form of a circular bottom ring. It is secured to the bottom of the lower pan 2 by adhesive or screws.

[0050] The overall shape of the energy-gathering pan stand in this embodiment is circular. Of course, it can also be square, square-round, elliptical or other polygonal shapes, etc., and can be set according to actual conditions.

[0051] Since the gas cooker provided in this embodiment includes the aforementioned energy-gathering pan rack, the technical advantages and effects that can be achieved by the gas cooker also include the technical advantages and effects that can be achieved by the aforementioned energy-gathering pan rack, which will not be repeated here.

[0052] Example 2

[0053] This embodiment provides an energy-gathering pan rack and a gas cooker having the same, the structure of which is basically the same as that of the above-mentioned embodiment 1, except that: Figure 3 As shown, the energy concentrating disk body also has a heat-insulating cavity 300 distributed around the central through hole.

[0054] Specifically, the energy-gathering plate pot rack also includes at least one middle partition layer 4, which is located in the secondary air preheating cavity 200 and divides the secondary air preheating cavity 200 into a double-cavity structure with an upper and lower layout. The upper part of the middle partition layer 4 is the secondary air preheating cavity 200, and the lower part of the middle partition layer 4 is the thermal insulation cavity 300, which is a closed cavity.

[0055] The middle partition layer 4 is located between the upper disk 1 and the lower disk 2, and the middle partition layer 4 is connected to the inner wall of the lower disk 2, and the middle partition layer 4 is spaced apart from the upper disk 1 and the lower disk 2. That is, the middle partition layer 4 separates the secondary air preheating cavity 200, and such separation forms a double-cavity structure with an upper and lower layout, that is, the secondary air preheating cavity 200 is between the middle partition layer 4 and the upper disk 1, and the thermal insulation cavity 300 is between the middle partition layer 4 and the lower disk 2. Among them, the secondary air preheating chamber 200 connects the burner 100 with the external environment, and the thermal insulation chamber 300 is relatively closed and located below the secondary air preheating chamber 200. The thermal insulation chamber 300 has an insulation function for the secondary air preheating chamber 200, ensuring that the secondary air flowing into the secondary air preheating chamber 200 maintains a relatively high-temperature preheating state, so as to enhance the preheating effect, increase the combustion flame temperature, effectively improve the combustion thermal efficiency, and at the same time play an insulating role for the liquid tray or gas stove panel.

[0056] The provision of the middle partition layer 4 makes the height of the secondary air preheating chamber 200 relatively shorter. At the same time, the secondary air preheating chamber 200 is close to the flame of the burner 100, which makes the secondary air in the secondary air preheating chamber 200 easier to heat and accelerates its flow rate, thereby accelerating the heat exchange rate. Therefore, the heating temperature of the secondary air in the secondary air preheating chamber 200 rises faster, making the secondary air preheating temperature in the secondary air preheating chamber 200 higher and more sufficient. In this way, the preheated secondary air participates in combustion, which can make the temperature of the combustion flame higher, thereby further improving the combustion thermal efficiency.

[0057] The upper surface (i.e., inner surface) of the intermediate layer 4 is provided with a reflective layer for reflecting heat. The reflective layer may be, but is not limited to, a light-colored, glossy surface or a reflective coating, which reflects heat upward. This structure further enhances the heating effect on the air in the secondary air preheating chamber 200, resulting in a higher and more complete secondary air preheating temperature in the secondary air preheating chamber 200. This further improves the utilization rate of combustion heat energy, further enhances combustion energy efficiency, and thus further improves combustion thermal efficiency.

[0058] Note that the above are only preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are possible for those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
