Outdoor oxygen taking pipe assembly of gas stove

Abstract

The invention relates to an outdoor oxygen taking pipe assembly of a gas stove. The outdoor oxygen taking pipe assembly is characterized by comprising a pipe connector and an oxygen taking pipe, one end of the pipe connector is used for being connected with a connecting hole in a gas stove shell, the other end of the pipe connector is connected with the oxygen taking pipe, and the other end of theoxygen taking pipe is used for communicating with the outdoor space; the circumferential wall of the end, away from the oxygen taking pipe, of the pipe connector is provided with a positioning step,and an inserting and connecting part is formed by a part between the end portion of the pipe connector and the positioning step; an annular groove is formed in the outer wall of the inserting and connecting part, and the distance between the annular groove and the positioning step is matched with the wall thickness of the part, around the connecting hole, of the gas stove shell; and an opening ring is embedded in the annular groove, and when the opening ring is not subjected to external force, the outer diameter is larger than the inner diameter of the connecting hole. The outdoor oxygen taking pipe assembly is used for achieving outdoor oxygen taking of the gas stove, sufficient gas combustion is achieved, and indoor oxygen consumption is reduced.

Description

technical field [0001] The invention relates to an accessory part of a gas cooker, in particular to an outdoor oxygen-taking pipe assembly applied to an outdoor oxygen-taking gas cooker, and belongs to the technical field of gas cooker design. Background technique [0002] With the continuous improvement of people's material living standards, the application of gas stoves is very common, almost an indispensable part of household appliances, reflecting the importance of gas stoves in life. However, gas stoves are also one of the main appliances that cause harm. The main reasons are as follows: [0003] Existing gas stoves basically use gas injection and air to mix into combustible gas. Since gas stoves are usually placed indoors, the flame is assisted by indoor oxygen during use, which will inevitably consume a large amount of oxygen in the room, causing the oxygen content in the home reduce. Although officials and gas suppliers will give safety warnings that "gas stoves sh...

AI Technical Summary

Problems solved by technology

When the cabinet door is closed, it will block the air inflow and affect the combustion.

The airtightness of the cabinet directly affects the gas-air mixing ratio. The better the airtightness, the lower the air ratio, the lower the fire temperature, and the lower the thermal efficiency.

Sometimes it is necessary to open the cabinet door to use, which is unreasonable and not applicable

Opening and closing the cabinet door during combustion will cause the air pressure in the cabinet to rise suddenly, the proportion of air in the mixed gas will increase, the flow speed will increase, and the flame will be extinguished; It is easy to cause the flame to go out instantly, and the unburned mixture spreads in the air, which is unsafe and prone to accidents

Some gas stoves adopt upward air intake, but there are holes and seams running through the bottom of the gas stove casing, which still cannot solve the above problems

In addition, there is no combustion-supporting structure at the stove head of the existing gas stove. When the valve of the gas assembly is opened relatively large, the problem of insufficient combustion of gas is prone to occur.

[0005] In summary, the air intake and combustion-supporting design of a gas stove are important factors related to its safety, rationality, and health, but the existing gas stoves cannot solve the above problems
