Abstract

The invention discloses a range hood, relates to the technical field of range hoods, and aims to solve the problem of easy shortening of the service life of a fan due to need of an outdoor unit to exchange heat and direct contact of sucked lampblack and steam with the fan in a traditional range hood. The range hood comprises a shell; a smoke inlet and a smoke outlet are formed in the shell; the smoke inlet is communicated indoors; the smoke outlet is communicated outdoors through a smoke discharge pipe; a flue is formed in the shell; and a fan is arranged in the flue. The range hood further comprises a lampblack condensation module; the lampblack condensation module includes a condenser shell connected to the external of the shell; a condenser is arranged in the condenser shell, and is connected with an evaporator; the evaporator is arranged in the smoke inlet; an intake port and an exhaust port are formed in the condenser shell; the intake port is communicated indoors; the exhaust port is connected with a heat exchange pipe; and the heat exchange pipe and a smoke discharge pipe are both communicated with a venturi pipe. The range hood can be used for treating kitchen lampblack.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a range hood. Background technique [0002] Along with the raising of people's living standard, the improvement of living conditions, the range hood becomes the necessary household appliance in the kitchen. The function of the range hood is to extract the heat, oily fume and steam from the kitchen to the outside. However, when the range hood is working, the smoke must pass through the centrifugal fan. The high-temperature oil fume and water vapor will have a certain impact on the service life of the centrifugal fan impact, and it is difficult to maintain the centrifugal fan. In addition, the oil fume discharged outside will cause certain pollution to the atmospheric environment. At present, the focus of the development of the range hood industry is more on how to discharge the kitchen fume, but there are deficiencies in the purification of the fume. [0003] An existing ra...
