Internal circulation type integrated cooker

Abstract

The invention discloses an internal circulation type integrated cooker which comprises a cooker body, an air suction opening, an air exhaust opening, an air suction channel, an air exhaust channel, a fan device and a purification device, the air suction opening, the air suction channel, the fan device, the air exhaust channel and the air exhaust opening are sequentially connected, the purification device is arranged in the air suction channel or the air exhaust channel, and the purification device is arranged in the air exhaust channel or the air exhaust channel. The cooker body comprises a shell, a cooking bench surface and a stove, the cooking bench surface is arranged on the shell, a sunken stove cavity is formed in the cooking bench surface, the stove is arranged in the stove cavity, the top of the stove is lower than the cooking bench surface, and the air suction opening and the air exhaust opening are formed in the stove cavity up and down. The air suction opening and the air exhaust opening are formed in the stove cavity, so that purified gas enters the same channel again along with polluted gas for re-purification treatment, the purification treatment capacity is improved, indoor air can be kept clean for a long time, and zero outdoor emission is achieved.

Description

technical field [0001] The invention relates to an integrated cooker, in particular to an internal circulation integrated cooker for indoor use. Background technique [0002] In my country's social catering and home catering, external exhaust range hoods are generally used, and the cooking habits of stir-frying, frying, and frying Chinese food will produce a lot of polluting gases such as oily fumes and toxic odors. These polluting gases are often directly discharged externally through external pipes. Even if the purification equipment is installed in the external pipeline, because it is discharged externally, the purification effect of the purification equipment is only to reduce pollution, not to eliminate pollution, and users have no motivation to maintain the purification equipment regularly. Therefore, the pollution discharge of social catering and home catering It will cause great damage and influence to the atmospheric environment. [0003] For this reason, people have...

Problems solved by technology

[0002] In my country's social catering and home catering, external exhaust range hoods are generally used, and the cooking habits of stir-frying, frying, and frying Chinese food will produce a lot of polluting gases such as oily fumes and toxic odors. These polluting gases are often directly discharged externally through external pipes. Even if the purification equipment is installed in the external pipeline, because it is discharged externally, the purification effect of the purification equipment is only to reduce pollution, not to eliminate pollution, and users have no motivation to maintain the purification equipment regularly. Therefore, the pollution discharge of social catering and home catering Will cause great damage and impact on the atmospheric environment

[0003] For this reason, people have invented the internal circulation oil fume purification technology, but the existing internal circulation oil fume purification technology, whether it is a single purification method or a composite purification method, has problems and defects: the polluted gas generated by cooking is purified. Afterwards, it directly returns to the indoor space, but due to the saturation of the purification material, the purification efficiency will decrease gradually, or due to the technical limitations of the purification material itself, the actual purification effect may be far from the theoretical purification effect, and it is impossible to achieve long-term indoor purification. clean
