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. A cover body is in an annular disc shape, at least one opening allowing secondary air to be fed is formed in the bottom of the cover body, and the bottom of the cover body is provided with an adjusting piece capable of moving in the circumferential direction relative to the bottom of the cover body so that the partial sectional area of the opening can be changed at least. Compared with the prior art, the energy gathering cover for the stove has the advantages that the opening allowing the secondary air to be fed is directly formedin the energy gathering cover, then the air outlet amount of a secondary air supplementing channel can be effectively adjusted by changing the sectional area of the opening, so that the effect of adjusting the air supplementing amount of the secondary air according to actual use needs is achieved, the problem that the smoke exhaust is small due to the fact that the energy gathering cover reducesthe height of a smoke discharging port 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
