Energy gathering cover for stove and gas stove applying energy gathering cover for stove

Abstract

The invention relates to an energy gathering cover for a stove and a gas stove applying the energy gathering cover for the stove. The energy gathering cover comprises an annular and discal cover body,wherein an internal enclosed opening for allowing secondary air to enter the cover body is formed at the inner side edge of the cover body, and the energy gathering cover is characterized by furthercomprising an adjusting part which is arranged on the inner side edge of the cover body and can stretch and retract relative to the inner part and outer part of the opening, an actuating part which isrotatably arranged on the lower surface of the bottom of the cover body and is used for driving an adjusting ring to stretch and retract relative to the inner part and outer part of the opening, andan elastic part which is acted on the adjusting ring and enables the adjusting ring to have a tendency to stretch externally. Compared with the prior art, the energy gathering cover and the gas stoveapplying the energy gathering cover for the stove have the advantages that the actuating part at the bottom of the cover body can drive the adjusting part to stretch and retract relative to the innerpart and outer part of the internal enclosed opening in the cover body so as to change the air amount of the secondary air entering the internal enclosed opening in the cover body, the effect of adjusting the air supplementing amount of the secondary air according to actual using requirement can be achieved, the problem that the smoke discharge is large due to the fact that an energy gathering cover is lowered is solved, and a combustor is in a stable and good combustion state.

Description

technical field [0001] The invention belongs to the technical field of gas stoves, and relates to an energy-collecting cover for stoves and a gas stove with the energy-collecting cover for stoves applied thereto. Background technique [0002] In the actual use of existing gas stoves, since the pot is placed on the pot support for heating, there is a certain space between the pot and the burner. A part escapes into the surrounding environment, causing energy waste; in order to solve the above problems, some heat collection and energy gathering have occurred in China in recent years, such as the "energy gathering ring for gas stove and gas stove with it" disclosed in Chinese patent CN203404823U , and as disclosed in the Chinese patent CN204042984U "a kind of energy-gathering gas stove", the gas stove also has an energy-gathering pot support, the above-mentioned energy-gathering ring structure can reduce the consumption of heat energy to a certain extent, improve The thermal e...

Problems solved by technology

[0002] In the actual use of existing gas stoves, since the pot is placed on the pot support for heating, there is a certain space between the pot and the burner. A part escapes into the surrounding environment, causing energy waste; in order to solve the above problems, some heat collection and energy gathering have occurred in China in recent years, such as the "energy gathering ring for gas stove and gas stove with it" disclosed in Chinese patent CN203404823U , and as disclosed in the Chinese patent CN204042984U "a kind of energy-gathering gas stove", the gas stove also has an energy-gathering pot support, the above-mentioned energy-gathering ring structure can reduce the consumption of heat energy to a certain extent, improve The thermal efficiency of the burner can also separate the flue gas from the secondary air supply channel. For this reason, the above-mentioned energy gathering rings generally have a secondary air supply channel for supplementing the secondary air, such as Chinese patent ZL201320460471.1 The disclosed "energy gathering ring for gas stove and gas stove with it" includes a first reflective ring and a second reflective ring that effectively increase the reflective energy gathering area of ​​the entire energy gathering ring, and the first reflective ring An air replenishment channel is provided between the upper end and the lower end of the second reflection ring. By setting the air replenishment channel, the problem of insufficient air replenishment during gas combustion can be solved. In order to reduce CO emissions, the secondary air replenishment should be as sufficient as possible, and It is often excess, and excess secondary air replenishment will take away a large part of the heat energy generated by gas combustion; in addition to achieving the energy-gathering effect by adding energy-gathering hoods, it can also reduce the way of smoke exhaust (smoke exhaust The mouth height refers to the distance from the highest plane on the edge of the energy-gathering hood to the bottom of the pot, that is, the effective height at which the smoke can be discharged). There is a lot of gas and heat. If the height of the exhaust port is reduced to 6mm, the smoke cannot be discharged smoothly, and the exhausted smoke will be correspondingly reduced, causing the smoke to gather in the inner space from the bottom of the pot to the energy-concentrating hood. , so that the secondary air supplementary channel increases the secondary air resistance, the supplementary air cannot be supplemented, the combustion is incomplete, the thermal efficiency decreases, and toxic and harmful gases such as carbon monoxide will be produced at the same time; but the secondary air supplementary channel is too large, and the secondary air is The amount of entrainment is large, and the heat taken away by the exhaust smoke increases, resulting in low thermal efficiency; the secondary air supply channel is too small, and the secondary air supply is insufficient, which will inevitably lead to incomplete gas, and the smoke emission exceeds the standard
