Blast burners and gas stoves

Abstract

The invention provides a blowing burner and a gas stove. The blowing burner comprises a burner assembly and a blower assembly, wherein the burner assembly comprises burner heads and gas distribution discs, the gas distribution discs are located above the burner heads and connected with the burner heads, each gas distribution disc is provided with multiple gas distribution channels, the cross sectional areas of at least two gas distribution channels of the multiple gas distribution channels are not the same, and the blower assembly is connected with the burner heads and used for leading air into the burner heads. According to the technical scheme, the gas flow of all the channels can be the same by changing the cross sectional areas of the channels on the gas distribution discs, therefore, gas can be fully burnt, and even heating can be achieved; meanwhile, air doors are arranged between the blower assembly and the burner heads, and the air which enters the burner heads can be accurately controlled, so that the proportion of the gas amount and the air amount of the burner heads can be moderate, and the sufficient burning of the gas can be guaranteed; in addition, the air amount in a blower can be controlled by using a stepless speed regulation device, and therefore the air amount can be changed continuously and evenly.

Description

technical field [0001] The invention relates to the field of household gas stoves, and more specifically, to a blast burner and a gas stove. Background technique [0002] With the increasing promotion of the concept of energy saving and environmental protection and the imminent implementation of new energy efficiency standards for cookers, the research on high-power and high-efficiency burners will be the future development trend. Although fan technology is widely used in gas water heaters, how to apply it to gas stoves is still in the research and development stage. The main reason is that technical problems such as flame uniformity and ignition problems have not been resolved. At present, when ordinary gas stoves on the market increase their firepower, yellow flames and backfires will occur due to insufficient air volume when the gas is burned. In order to solve the above problems, a fan is usually added to the gas stove to force the air, but because the air volume contro...

AI Technical Summary

Problems solved by technology

In order to solve the above problems, a fan is usually added to the gas stove to force the air, but because the air volume control accuracy cannot meet the requirements, the phenomenon of flame separation will occur in the cold state or when the gas pressure is too high, which affects the normal operation of the user. use

In addition, for ordinary gas stoves, the air flow of the gas distribution plate on the burner is not the same, resulting in uneven flames, which in turn makes the flames in the entire burner area uneven, and the parts with long flames appear due to incomplete combustion. The phenomenon of CO content exceeding the standard and yellow flame

It not only wastes fuel, but also pollutes the environment and damages the health of users
