AI Technical Summary

Technical Problem

In the design of the exhaust channel of existing gas stoves, there are problems such as the exhaust channel being too large, resulting in a short contact time between the smoke and the bottom of the pot and reducing thermal efficiency, and the exhaust channel being too small, resulting in incomplete combustion of the flame and the generation of harmful gases.

Method used

The smoke baffle is made of shape memory alloy. When the temperature is low, it is in a first set shape to increase the flow area of ​​the exhaust channel. When the temperature is high, it deforms into a second set shape to reduce the flow area of ​​the exhaust channel. Combined with the pot rack assembly design, it optimizes smoke exhaust and heat exchange.

Benefits of technology

At low temperatures, the smoke is quickly discharged to reduce the generation of harmful gases. At high temperatures, the heat exchange time between the smoke and the bottom of the pot is increased, thereby improving the thermal efficiency of the gas stove.

Abstract

The utility model discloses a pot rack assembly and a gas stove, and belongs to the field of kitchen wares, the pot rack assembly is used for supporting a pot, the pot rack assembly comprises a pot rack body and a smoke blocking ring, and the pot rack body is provided with an exhaust channel; the smoke blocking ring is arranged on the pot rack body and located on an exhaust path of the exhaust channel, at least part of the smoke blocking ring is made of shape memory alloy, when the temperature is smaller than the deformation temperature, the smoke blocking ring is in a first set shape, and when the temperature is larger than or equal to the deformation temperature, the smoke blocking ring is in a second set shape so as to reduce the circulation area of the exhaust channel. The gas stove comprises the pot rack assembly. When the temperature is low, the smoke blocking ring is in the first set shape, the circulation area of the exhaust channel is large, smoke can be exhausted rapidly, and generation of harmful gas is reduced; along with gradual increase of the temperature, when the temperature reaches the deformation temperature, the smoke blocking ring piece deforms to be in the second set shape, the circulation area of the exhaust channel is reduced, the heat exchange time of high-temperature smoke and the pan bottom is prolonged, and the heat efficiency is improved.
