Description

Household gas stove with auxiliary air inlet fan Technical Field The utility model relates to the technical field of gas cookers, in particular to a household gas cooker with an auxiliary air inlet fan, aiming at improving combustion efficiency and thermal efficiency. Background The household gas stove is used as a main heating device for kitchen cooking and is widely applied to the fields of resident families, catering industry and the like. The traditional household gas stove mostly adopts an atmospheric burner structure, gas is sprayed out at high speed through a natural gas or liquefied gas nozzle, negative pressure is formed in an injection pipe to suck air with a certain proportion, primary mixing is realized, and then ignition combustion is carried out at the head part of the burner. The advantages of such a structure are simple structure, low cost, mature manufacturing process, but also significant drawbacks. First, the natural injection air intake is limited. As the introduction of primary air depends on the negative pressure suction formed by the high-speed jet flow of the fuel gas, once the jet flow speed is reduced, or the fuel gas pressure is unstable and the air duct is blocked, the air inlet is insufficient, the phenomenon of red fire appears, which indicates incomplete combustion and causes energy waste and pollution emission. Secondly, in a closed or unsmooth kitchen environment, the oxygen concentration in the space where the burner is positioned is insufficient, and the air exchange is slow, so that the condition of incomplete combustion is further aggravated. This not only reduces the thermal efficiency, but also causes a large amount of harmful products such as carbon monoxide, carbon black, etc., which are harmful to the health of users and the safety of the environment. Aiming at the defects, part of products in the industry begin to introduce a fan combustion-supporting technology, and air is actively fed into a combustion area by utilizing an electric fan so as to improve the mixing efficiency of the air and the fuel gas. However, the products are mostly used for commercial high-power stoves in the market at present, and the fans are large in structure and complex in circuit and are not suitable for small stoves in household scenes. Disclosure of utility model The utility model aims at overcoming the defects and shortcomings of the prior art, and provides a household gas stove with an auxiliary air inlet fan, which can improve the air inlet quantity of the household gas stove, has the advantages of sufficient combustion air supply, stable flame and more sufficient combustion, has a simple structure, is convenient to install and reform, and is suitable for daily use in families. In order to achieve the purpose, the burner adopts the following technical scheme that the burner comprises a burner body base 1 and a burner 2, and further comprises an air inlet fan 3, wherein the burner 2 and the air inlet fan 3 are arranged on the burner body base 1, an air outlet of the air inlet fan 3 is provided with two air outlet pipes 31, and the two air outlet pipes 31 are respectively inserted into a main air inlet 21 and a side air inlet 22 of the burner 2. The air outlet pipe 31 is inserted in the main air inlet 21 and the side air inlet 22 in a suspended manner, and the main air inlet 21 and the side air inlet 22 are both in a non-sealing manner. The air outlet pipe 31 is directly inserted into the main air inlet 21 and the side air inlet 22, the main air inlet 21 and the side air inlet 22 are both in a non-sealing mode, and the main air inlet 21 and the side air inlet 22 can still work in a natural air inlet mode in a normal state. The air inlet fan 3 is a blower fan driven by a direct current motor. The adoption direct current motor can guarantee the low pressure operation of fan motor, can guarantee the long-time operation of fan, also can guarantee the stability and the safety of long-time operation, because the fan motor that sets up at the combustor annex can work in the abominable environment of high temperature for a long time. The air outlet pipe 31 is an elastic hose, the air outlet of the air inlet fan 3 is provided with two plug-in pipes 32, and the air outlet pipe 31 is plugged on the plug-in pipes 32.
