Description

A natural gas stove

technical field

The invention belongs to the technical field of gas stoves, and in particular relates to a natural gas kang stove which uses natural gas for cooking and kang heating.

Background technique

In northern my country, there are still a large number of bungalow households in the suburbs and rural areas of small and medium-sized cities in most areas. Each of these bungalow households has stoves and kangs. , not only delays in work and trouble, but also pollutes the environment and wastes resources. There are now many bungalow households in many cities that have been connected to natural gas. However, the natural gas stoves on the market can only cook but not kang, and the firepower is small, which cannot meet people's requirements. The exhaust gas after burning will affect people's health. Especially in summer, the strong heat radiation makes the kitchen extremely hot. Therefore, these bungalow residents connected to natural gas urgently hope to have a kind of gas equipment that can not only cook, but also use waste heat to burn kang, with sufficient firepower, no exhaust gas pollution, no heat in the kitchen, energy saving, environmental protection, cost saving and practical gas equipment to satisfy them demand.

Wherein: the fire power distributor is a flat plate, and through holes with different radii are distributed on the flat plate. When the fire power distribution of the natural gas burning plate is uneven, the natural gas of the present invention can be adjusted by adjusting the size and position of the through holes in the fire power distributor. The heat of the Kang stove is balanced.

The wind rotator is a device with a closed top and a plurality of evenly distributed slanted pieces underneath. When the wind from the fan enters the wind rotator, the wind direction changes from vertical to horizontal, and then the wind direction is deflected by the slanted pieces. , and then meet the furnace wall to make it rotate to achieve the purpose of uniform blowing.

The natural gas burning disk is ring-shaped, and a groove is opened in the middle of the ring shape, and small holes are opened in the groove. When the natural gas enters the groove, it will spray out evenly from many small holes.

The natural gas kang stove of the present invention is installed in the stove in the family, and it can be directly used for cooking after opening, and the excess heat can be directly transferred to the kang through the channel between the stove and the kang, which satisfies people's need to burn the kang. It can also be directly used for burning kang, and the waste gas is discharged outside through the chimney, which has no waste gas pollution, and is energy-saving and environmentally friendly.
