Implementation mode one
The embodiment provides a gas stove which comprises a gas stove table top, a burner arranged on the gas stove table top, and a gas stove pot rack, wherein the gas stove pot rack is erected on the gas stove table top and is located right above the burner and used for placing a pot.
As shown in fig. 1 to 3, the gas stove wok stand in the present embodiment includes an infrared radiation net 1, a support 2 and a base 3, wherein the base 3 is supported on a table top of the gas stove, the support 2 is installed on the base 3, the infrared radiation net 1 is installed on the support 2, the infrared radiation net 1 is located right above a burner, and the infrared radiation net 1 is a mesh structure.
The gas stove pot frame provided by the embodiment has a simple structure, can be directly applied to the existing atmospheric gas stove, can convert part of flame heat into infrared radiation of the infrared radiation net 1 by utilizing high-temperature gas energy far away from the pot bottom, increases the energy proportion of the infrared radiation received by the pot, optimizes the energy transfer mode, improves the utilization rate of the flame energy, and obviously improves the heat efficiency of the gas stove.
Alternatively, the gas stove pot rack may comprise one or more layers of infrared radiation nets 1, and when the plurality of layers of infrared radiation nets 1 are provided, two adjacent layers of infrared radiation nets 1 are installed on the bracket 2 at intervals along the height direction. The thermal efficiency of the gas stove can be further improved by increasing the number of layers of the infrared radiation net 1.
Preferably, a plurality of supports 2 are provided, and the plurality of supports 2 are uniformly arranged along the circumferential direction of the infrared radiation net 1 so as to uniformly and stably support the infrared radiation net 1.
In the present embodiment, the shape of the infrared radiation net 1 may be, but not limited to, a circle, and may be a polygon, for example, a quadrangle, a hexagon, or the like, and may be selected according to actual circumstances.
The shape of the base 3 in this embodiment may be, but not limited to, a quadrilateral, a circle or other polygons, and may be selected according to actual situations. Preferably, the base 3 is square, and further preferably, the side length of the base 3 is approximately the same as the diameter of the infrared radiation net 1, so that the appearance is more attractive and the whole structure is more compact.
Optionally, the through holes are distributed on the infrared radiation net 1 and are uniformly distributed, so that flame of the gas stove can uniformly penetrate through the infrared radiation net 1 to heat the bottom of the pan, and the heating effect is better.
Preferably, the through-holes are uniformly distributed in ranks or uniformly distributed along the circumferential direction on the infrared radiation net 1, which arrangement mode is specifically adopted, and the selection can be carried out according to the actual situation, and the mode of uniform distribution in ranks is preferably selected by the embodiment. Of course, in other embodiments, the through holes on the infrared radiation net 1 may be non-uniformly distributed, and the same functional function can be achieved.
The cross-sectional shape of the through-holes on the infrared radiation screen 1 is circular or polygonal, such as square. The larger the size of the through hole is, the smaller the effective area of the infrared radiation net 1 is, and the heat efficiency improvement effect is not obvious; the smaller the size of the through hole is, the larger the gas flow resistance is, and the amount of primary air and secondary air can be reduced, so that the CO in the flue gas is excessive. Therefore, the diameter or the side length of the through hole preferably ranges from 2mm to 4mm, and the specific value may be selected according to actual conditions, which is not specifically limited in this embodiment.
In this embodiment, the material of the infrared radiation net 1 may be a metal net, such as an iron-chromium-aluminum metal net, or other non-metal materials with infrared emission capability.
Further, the surface of the infrared radiation net 1 is provided with a catalyst coating. When the burning flue gas passes through the infrared radiation net 1, harmful gases such as CO, NOx and the like in the flue gas react and decompose with the catalyst on the surface of the flue gas, thereby reducing the emission of pollutants and improving the environmental protection performance.
When the gas stove pot frame in the embodiment is used, the pot frame is placed on the table top of the gas stove, and the infrared radiation net 1 is positioned at a certain height right above the burner. The flame of the gas stove penetrates through the infrared radiation net 1 to heat the bottom of the pan, and meanwhile, part of heat of the flame is absorbed by the infrared radiation net 1, so that the temperature of the flame is increased to generate infrared radiation to heat the pan. The energy transfer mode of the flame heating pot of the atmospheric gas cooker comprises a radiation mode and a convection mode, wherein the heat convection energy transfer rate is limited, the heat of high-temperature flue gas is difficult to be completely absorbed by the pot, particularly, the heat of the high-temperature flue gas at a position far away from the pot bottom is less utilized, the flue gas discharged from the heating surface of the pot bottom still has high temperature, and partial energy waste can be caused. After the pot frame is adopted, the energy of high-temperature gas far away from the bottom of the pot is further utilized, and meanwhile, the energy of the flame for heating the pot comprises the heat radiation of the flame, the heat convection of high-temperature flue gas and the heat radiation of high-temperature solids (the infrared radiation net 1), so that the proportion of the heat radiation is greatly increased. The infrared radiation penetrability is strong, and the heating effect is direct, and heating efficiency is high, therefore flame heat transfer mode obtains improving, the utilization ratio improves, and the gas-cooker thermal efficiency is showing and is promoting.
Second embodiment
The embodiment provides a gas stove wok stand, which has basically the same structure as the gas stove wok stand in the first embodiment, and the difference is that:
as shown in fig. 4 to 6, the infrared radiation net 1 in the present embodiment is a ring-shaped structure, and a center hole through which flames pass is provided at the center thereof. When the pot frame is used, the pot frame is placed on the table top of the gas stove, the infrared radiation net 1 is located at a certain height right above the burner, so that flame of the gas stove penetrates through a center hole of the infrared radiation net 1 to burn, and outer flame burns on the lower side of the infrared radiation net 1. The structure of the central hole ensures that the flame of the inner ring can not be in direct contact with the infrared radiation net 1, thereby avoiding the temperature reduction and insufficient oxygen supply of the flame of the inner ring and ensuring that excessive incomplete combustion products CO can not be generated in the flue gas. The infrared radiation net 1 is heated by the upper inner ring flame and the lower outer ring flame, and atoms in the material are excited to generate infrared radiation to directly heat the pot bottom. The infrared ray has extremely strong penetrating power and thermal effect, and the heating efficiency is superior to the convection heat exchange of flame high-temperature gas. Therefore, the heat transfer mode is optimized by converting the flame heat into the infrared radiation of the infrared radiation net 1, so that the heating effect of the pot bottom is improved. In addition, due to the fluctuant surface shape of the infrared radiation net 1 and the different fluid flow velocities of the upper side and the lower side of the infrared radiation net, the flow of high-temperature flue gas is disturbed to generate small vortex, the heat convection coefficient of the flue gas and the bottom of the pot is increased, and the utilization rate of the heat of the flue gas is increased. The superposition of the two effects obviously increases the infrared radiation proportion and enhances the convection heat exchange effect, and the heat efficiency of the gas stove is obviously improved.
The shape of the central hole can be, but not limited to, circular, and can also be polygonal, such as quadrilateral, hexagon, and the like, which is selected according to the actual situation.
The larger the diameter of the central hole is, the smaller the area of the infrared radiation net 1 is, and the improvement of the thermal efficiency is not obvious; the smaller the diameter of the central hole, the greater the resistance to gas flow, the higher the volume fraction of CO in the flue gas. Preferably, the aperture of the central hole ranges from 50mm to 80mm, and the specific value is selected according to the actual situation, which is not specifically limited in this embodiment.
Note that the above description is only for the preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments illustrated herein, but is capable of various obvious modifications, rearrangements and substitutions without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
