Home kitchen fresh air system

Abstract

The invention discloses a home kitchen fresh air system. The home kitchen fresh air system is composed of a filtering device (1), an air supplement fan (2), a sensible heat exchanger (3), a purification device (4), a smoke exhaust ventilator (5), a check valve (6), a cooking bench air port (7), a refrigerating chamber inner unit (8), a refrigerating chamber outer unit (9), an air supplement duct (10), a control module (11), pipelines and valves. Fresh air fed by the fresh air system enters a kitchen through air ports formed in the periphery of a table top of a cooking bench and works with the smoke exhaust ventilator coordinately, organized air feeding and exhausting are formed in the cooking range area, thus, the purpose that outdoor particulate pollutants are kept out is achieved while discharging of home kitchen pollutants is accelerated, and the suitability degree of the indoor temperature of the kitchen is increased in an energy-saving mode.

Description

technical field [0001] The invention relates to a fresh air system. More specifically, it relates to a family kitchen fresh air system. Background technique [0002] Family kitchens, especially Chinese-style kitchens, are used to frying and frying, which will produce a lot of high-temperature oily fumes and steam. In order to eliminate these oily fumes and steam, range hoods are generally installed. At present, the air volume of the exhaust fume fan is 900m3 / h, and some even reach 1200m3 / h. Although the rated air volume of the range hood is large, there is no effective supplementary air source in the closed kitchen, resulting in the effective air volume of the range hood being greatly reduced, and the effect of exhausting oil fume is greatly reduced. Opening windows for ventilation can solve the problem of supplementary air in the kitchen, but the outdoor temperature varies greatly with the seasons, and most of the time it cannot meet the indoor comfort requirements.

Problems solved by technology

[0007] In addition, there are currently some kitchen fresh air supply devices, but they are all based on the fact that the fresh air outlet can send outdoor fresh air to the breathing area of ​​the cooking staff, so that the cooking staff can breathe smoothly, but it is difficult to achieve a good oil fume exhaust effect
