Description

Combustion smoke independent exhaust device for household integrated stove

technical field

The utility model relates to a household gas cooker, in particular to a combustion smoke independent discharge device of a household integrated cooker.

Background technique

Three meals a day are indispensable in people's life, and three meals a day are inseparable from cooking and cooking. As we all know, Chinese people's cooking habits are mainly frying, frying, and frying. Ordinary daily stoves are usually equipped with a range hood on the top. To absorb the cooking fume and combustion fume, because there is a distance of 70cm-90cm between the range hood and the cooking pot, the fumes tend to spread during the rising process, affected by the wind and people's cooking actions , so the suction effect is poor, and if the space above the stove is too low, cooking is inconvenient. Therefore, the industry has developed and launched the integrated stove with lower row of ring suction and the integrated stove with lower row of side suction. This kind of integrated cooker sets the suction port of the range hood on the side of the wall above the cooker and on the periphery of the cooker slightly higher than the edge of the pot, so as to be as close as possible to the source of oil fume and basically eliminate airflow and cooking. Actions interfere and affect the flow of oil fume, and the effect of absorbing oil fume in the same negative pressure state is greatly improved, but it is the suction port of the smoke that is very close to the stove, and the strong suction when sucking oil fume also produces a strong suction on the combustion gas under the frying pan. It has a great drainage effect, which accelerates the flow rate of various gases around the burner, resulting in a decrease in the heat accumulation effect and a large loss of heat energy. As a result, the thermal efficiency of the gas cooker is greatly reduced. After testing by the superior authoritative department, the thermal efficiency of the integrated stove is only about 40% when the range hood fan is turned on! At present, the thermal efficiency test method adopts the regulations of "Household Gas Cookers" GB/16410-2007, that is, the surrounding wind speed is less than 0.3 m/s when testing the thermal efficiency, so the range hood fan cannot be turned on when the integrated cooker is tested. The domestic authoritative department has started to draft the national standard of "Integrated Stoves". At that time, the integrated stoves currently on the market will not be able to be listed because they cannot meet the thermal efficiency indicators.

For this reason, how to reduce the thermal efficiency loss of the integrated stove when the range hood is turned on so that it can meet the requirements of energy saving and high efficiency is the key to the future survival of the integrated stove.

Utility model content

The purpose of the utility model is to provide an independent discharge device for combustion flue gas of a household gas integrated stove that can improve the thermal efficiency of the integrated stove.

The specific way to realize the technical solution of the purpose of this utility model is: design a kind of device that comprises the gas-gathering bin of burning flue gas and the exhaust conduit that is communicated with it, set the gas-gathering bin of burning flue gas into ring shape, in The combustion flue gas conduction hole is opened on the side wall facing the stove to inhale the flue gas. The gas collection bin ring of the combustion flue gas is placed around the burner of the gas integrated stove. After the wok is put on it, an isolated independent space can be formed , so that the combustion flue gas can only flow into the gas collection bin of the combustion flue gas from the flue gas conduction hole; "shaped, the inner edge of the upper part is set to form a line or surface seal with the bottom of the frying pan; in addition, in order to utilize the waste heat of the combustion flue gas, the exhaust duct can also be connected with an air-water heat exchanger. Then discharge.

The combustion smoke independent exhaust device of the household integrated cooker of the utility model is provided with an independent combustion smoke exhaust device inside the ring-shaped gas-collecting chamber of the lower row smoke exhaust device part of the ordinary integrated cooker, so that the combustion smoke is isolated In the space formed by the lower bottom of the pot and the annular combustion flue gas collection bin, the combustion flue gas enters the gas collection bin from the combustion flue conduction hole on the side wall of the annular combustion flue gas collection bin and then passes through the special combustion flue gas Connect the tube to discharge. It overcomes the mixed discharge of combustion fumes and cooking fumes of ordinary integrated stoves. Due to the high suction strength of exhaust fumes, the airflow speed near the burner flame of the cooker is accelerated, the temperature accumulation effect in the local area of the bottom of the pot is poor, the heat loss is large, and the thermal efficiency of the cooker is reduced. defect. And it has the advantages of simple structure, easy implementation and safe use.
