Abstract

The invention discloses a range hood, which comprises a smoke collecting hood, a fan frame arranged above the smoke collecting hood and a fan system arranged in the fan frame, the fan system includes a volute, and the smoke collecting hood includes a left side wall and a fan frame. On the right side wall, the range hood also includes an anti-smoke device installed in the fume collecting hood and fan frame. The anti-smoke device includes a first conduit, a first latex, a second conduit and a second latex. One end of the first conduit is It is in fluid communication with the volute, and the other end extends to the left side wall. One end of the second conduit is in fluid communication with the volute, and the other end extends to the right side wall. The left side wall is open at the corresponding end of the first conduit, and the right side The wall is open at a place corresponding to the end of the second conduit, the first latex is arranged in the end of the first conduit close to the left side wall, and the second latex is arranged in the end of the second conduit close to the right side wall, the first latex and the second latex Each has an initial state of being accommodated in a corresponding duct, and an expanded state of protruding to the outside of the fume collecting hood under the action of pressure in the corresponding duct.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. The range hood uses the principle of fluid dynamics to work, sucks and exhausts the range hood through a centrifugal fan installed inside the range hood, and uses a filter to filter some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the oil fume under the range hood is sucked into the fan, and after being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] Before the installation of household range hoods, the cabinets are generally designed and installed according to the dimensions of the range hoods, the installation s...
