Energy gathering ring for gas stove

Technical Field

The utility model relates to an gather and encircle for gas-cooker belongs to domestic gas-cooker technical field.

Background

At present, a gas stove is important kitchen equipment, along with the increasing of the attention degree on energy saving, the improvement of the heat efficiency is generally realized in the industry by considering the structure of a combustor so as to achieve the aim of energy saving. However, the method for actively improving the thermal efficiency is difficult to break through the bottleneck of the current technology, and the improvement range of the thermal efficiency is limited. At present, in order to improve the thermal efficiency of gas combustion, some manufacturers add an energy-gathering ring on a liquid-containing plate of a gas stove, wherein the energy-gathering ring is made of an energy-gathering annular plate, so that a burner is surrounded by the energy-gathering ring, and the heat flowing into air can be reduced when the gas is combusted, thereby improving the thermal efficiency of combustion. Chinese patents with publication numbers CN106152202A and CN 304002332S, CN207179747U provide various forms of energy-gathering rings, but most of the existing energy-gathering rings are made of iron-based metal materials, so that the heat-insulating property is poor, and the energy-saving effect is not ideal. In chinese patent No. CN208907645U, the applicant proposed using heat-insulating cotton in the energy-gathering ring to reduce heat loss, but the structure is complex and the heat-insulating effect is limited. In addition, because the energy gathering ring is arranged below the combustor, the temperature is high when the energy gathering ring is used, the iron-based metal material is easy to oxidize at high temperature, and the surface is easy to peel off and burn.

In summary, how to design the energy collecting ring to improve the thermal efficiency of the gas stove is a problem to be solved urgently in the field.
