Description
Technical Field
The invention belongs to the field of stoves, and particularly relates to a boiler stand capable of preheating and supporting combustion.
Background
Along with the continuous improvement of the scientific and technical level, the high efficiency, energy conservation and low carbon and environmental protection are one of the important requirements of users on the gas cooker. On the premise of the same heat load, the burner of the gas stove can not release more heat during combustion of gas, and how to make heat exchange between the burner and the pan bottom becomes an effective way for improving the heat efficiency of the burner for various manufacturers.
At present, the double-layer pot support is the most technical scheme adopted by the existing high-efficiency gas cooker, but a certain distance is reserved between a pot and a burner due to the existence of the pot support, and besides being used for heating, a considerable part of heat energy generated by gas combustion is diffused into the surrounding environment.
At present, the improvement of a double-layer pot support mainly focuses on forming a secondary preheating air channel between the bottom of the pot support and a liquid containing disc, so that the combustion of fuel gas is promoted, and the utilization rate of the fuel gas is improved. In such improvements, the upper panel of the pot rack is in close connection with the lower bottom plate of the pot rack, and air between the upper panel of the pot rack and the lower bottom plate of the pot rack is not circulated, so that heat transfer from the upper panel of the pot rack to the lower bottom plate of the pot rack is blocked, but the lower bottom plate of the pot rack is generally placed on a gas stove panel or a liquid containing plate, so that the problem of temperature rise of the panel is easily caused in the combustion process, and heat accumulated by the upper panel of the pot rack cannot be fully utilized.
Therefore, the double-layer pot support is improved, the energy consumption of the product is reduced, and the heat efficiency is improved.
