It is possible that your exhaust is not in the right direction, and the wind outside the house is just blowing against the window. You'd better install a large hollow tube 300mm in diameter on the stove, so that the smoke is discharged from the tube.
At present, the rural areas are using the stove pit fire pot cooking way, does not apply to any of the existing hood, in cooking will produce a lot of oil, smoke, gas, these oil, smoke, gas in the harmful substances in the human body will cause great harm, in order to minimize the harm can only rely on the opening of the door. Open the window to realize the purpose of cooking exhaust fumes, northern winter open windows and doors exhaust fumes will appear cold wind icing fumes full of house phenomenon, bringing a lot of inconvenience to people's lives. In the northern countryside heating is mainly stove pit burning kang to heating, room temperature is very low only kang is hot, burning kang cooking will cause the room smoke can not be discharged and the low temperature inside the room problem, to people's lives bring hidden trouble and inconvenience. The utility model relates to a kind of exhaust hot air kanglian cooker, including cooker countertop, ring-shaped suction channel, combustion chamber, smoke outlet, pot body and pot cover; the lower part of the cooker is equipped with a combustion chamber, which is connected to the smoke outlet, and the upper part of the combustion chamber of the cooker is mounted with a pot and a pot cover; the pot body is mounted on the bottom of cooker countertop, and the characteristics are as follows: there is a ring-shaped suction channel mounted on the outer wall of the combustion chamber under the cooker countertop, and there is a ring-shaped suction opening on the inner side of the ring-shaped suction channel, and there is a ring-shaped suction opening on the inner side of the ring-shaped suction channel. Suction port, ring-shaped suction port fixed connected to the filter, ring-shaped suction channel on the outside of a fan port connected to a micro-centrifugal fan; ring-shaped suction channel and combustion chamber combustion chamber wall outside the hot air heating channel with a ring-shaped cavity sandwich, hot air heating channel for the ring-shaped cavity sandwich, sandwich at the upper end of the outer wall there is an outlet, sandwich at the lower end of the air inlet, the air inlet is installed on the fan. The exhaust effect is very obvious; the fan on the mezzanine of the hot air heating channel device will blow the heat source out of the mezzanine for direct heating, simple operation, easy to use, easy to disassemble and install. Prospect analysis of the field of application of the technology: the three northeastern provinces, for example, rural townships, every family with the kang connected to the kettle, the existing range hood The purpose of this utility model is to provide an exhaust hot air kang connected to the stove, which is installed under the cooker countertop suction device, can be better smoke out of the outdoors, to solve the indoor pollution and the inconvenience of the opening of the windows and doors; suction device under the combustion chamber with the outside of the ring of the hot air heating channel device The heat from the wall of the combustion chamber can be directly supplied to the room through the fan to warm the room, solving the problem of low indoor temperature. Benefit analysis: annual production of 50,000-100,000 units, each wholesale profit of 400 yuan, the rural world blank, rural domestic blank, no competitive products, the development of new trends, hit the market to earn ten million dollars a year. Products in bulk head to put the Northeast market, product performance is superior, beautiful and practical, is the construction of new rural areas, rural kitchens preferred home appliances.
