Gas stove with combustion efficiency adjusting function

Abstract

The invention relates to a gas stove with a combustion efficiency adjusting function. The gas stove comprises a combustor, the combustor comprises a base and an outer ring fire cover, an outer ring gas mixing chamber is formed between the outer ring fire cover and the base, and the outer wall surface of the outer ring gas mixing chamber is provided with fire outlet holes along the circumferentialdirection; and the gas stove is characterized by further comprising an adjusting piece, the adjusting piece is provided with an annular body, a central hole allowing the top of the combustor to penetrate out is defined by the edge of the inner side of the body, the top of the body is connected with an adjusting ring, and the adjusting ring can at least partially shield the fire outlet hole area ofthe outer ring gas mixing chamber along with movement of the adjusting piece. Compared with the prior art, the gas stove has the advantages that the adjusting structure capable of being matched withthe combustor is provided, the central hole of the adjusting piece of the adjusting structure is used for allowing the top of the combustor to penetrate out and then is installed, the adjusting ring of the adjusting piece can at least partially shield the fire outlet holes of the combustor, and therefore the speed of spraying mixed gas from the fire outlet holes of the combustor is adjusted.

Description

technical field [0001] The invention relates to the field of gas stoves, in particular to a gas stove with adjustable combustion efficiency. Background technique [0002] The primary air coefficient of existing atmospheric stove burners is generally 0.4-0.7, and the premixed air cannot reach the air volume required for complete combustion. In addition to various factors, a certain amount of secondary air is required, and in order to reduce CO emission, secondary air supplement should be as sufficient as possible. At present, there are various ways of replenishing air for stove burners. Generally, there are side air intake and bottom air intake. The air inlet is supplemented with secondary air, and the way of lower air intake is to open the lower air inlet at the base base, and the air under the cooker is supplemented with secondary air through the lower air inlet. Among them, although the way of side air intake has the advantages of small air intake resistance and large ai...

Problems solved by technology

However, it is difficult to meet the diversity of user needs through flow control. For example, a Chinese utility model patent "A New Type of Gas Stove Flame Cover" with the patent number ZL201620432553.9 (authorized announcement number is CN205783145U), the patent includes the block body , the middle part of the block body contains two hinged parts, the two hinged parts are block one and block two respectively, block one and block two respectively contain fire holes, when block one and block two do not rotate for circular structure

The direction of the fire hole is adjusted by rotating the first block relative to the second block. Its main function is to facilitate concentrated firepower for cooking. It can be seen that the adjustment method is relatively simple, and the firepower adjustment is relatively limited.
